Further items of note for using Visual Studio Code (vscode) and C#
Install the compatible .NET SDK as per the section above.
Also install the vscode extensions (Ctrl-Shift-X) for C# and NuGet.
Follow the instruction here
to create and run the “Hello World” console project using C#.
You may also create a NUnit starter project using the command line dotnet new NUnit.
Make sure the file %appdata%\NuGet\nuget.config is configured properly as some developers reported that it will be empty due to some issues.
If nuget.config is empty, or not configured properly, then .NET builds will fail for Selenium Projects.
Add the following section to the file nuget.config if it is empty:
For more info about nuget.configclick here.
You may have to customize nuget.config to meet you needs.
Now, go back to vscode, press Ctrl-Shift-P, and type “NuGet Add Package”, and enter the required Selenium packages such as Selenium.WebDriver.
Press Enter and select the version.
Now you can use the examples in the documentation related to C# with vscode.
You can see the minimum required version of Ruby for any given Selenium version
on rubygems.org
Selenium Manager helps you to get a working environment to run Selenium out of the box. Beta 1
of Selenium Manager will configure the drivers for Chrome, Firefox, and Edge if they are not
found on the PATH. No extra configuration is needed. Future releases of Selenium Manager
will eventually even download browsers if necessary.
To see what directories are already on PATH, open a Command Prompt and execute:
echo %PATH%
If the location to your driver is not already in a directory listed,
you can add a new directory to PATH:
setx PATH "%PATH%;C:\WebDriver\bin"
ドライバを起動することで、正しく追加されているかどうかをテストできます。
chromedriver.exe
If your PATH is configured correctly,
PATH が正しく構成されている場合、ドライバーの起動に関連する出力が表示されます。

Synchronizing the code with the current state of the browser is one of the biggest challenges
with Selenium, and doing it well is an advanced topic.
Essentially you want to make sure that the element is on the page before you attempt to locate it
and the element is in an interactable state before you attempt to interact with it.
An implicit wait is rarely the best solution, but it’s the easiest to demonstrate here, so
we’ll use it as a placeholder.
If you are using Selenium for testing,
you will want to execute your Selenium code using test runner tools.

These are capabilities and features specific to Microsoft Internet Explorer browsers.
As of June 2022, Selenium officially no longer supports standalone Internet Explorer.
The Internet Explorer driver still supports running Microsoft Edge in “IE Compatibility Mode.”
Special considerations
The IE Driver is the only driver maintained by the Selenium Project directly.
While binaries for both the 32-bit and 64-bit
versions of Internet Explorer are available, there are some
known limitations
with the 64-bit driver. As such it is recommended to use the 32-bit driver.
Additional information about using Internet Explorer can be found on the
IE Driver Server page
Options
Starting a Microsoft Edge browser in Internet Explorer Compatibility mode with basic defined options looks like this:
If IE is not present on the system (default in Windows 11), you do not need to
use the two parameters above. IE Driver will use Edge and will automatically locate it.
If IE and Edge are both present on the system, you only need to set attaching to Edge,
IE Driver will automatically locate Edge on your system.
As of Internet Explorer Driver v4.7.0:
No longer need to set Ignore Zoom Level for Edge in IE Mode
Here are a few common use cases with different capabilities:

These are capabilities and features specific to Apple Safari browsers.
Unlike Chromium and Firefox drivers, the safaridriver is installed with the Operating System.
To enable automation on Safari, run the following command from the terminal:
safaridriver --enable

The file upload dialog could be handled using Selenium,
when the input element is of type file.
An example of it, could be found on this
web page- https://the-internet.herokuapp.com/upload
We will require to have a file available with us,
which we need to upload.
The code to upload the file for different programming
languages will be as follows -
importjava.util.concurrent.TimeUnit;importorg.openqa.selenium.By;importorg.openqa.selenium.WebDriver;importorg.openqa.selenium.chrome.ChromeDriver;importio.github.bonigarcia.wdm.WebDriverManager;classfileUploadDoc{publicstaticvoidmain(String[]args){WebDriverManager.chromedriver().setup();WebDriverdriver=newChromeDriver();driver.manage().timeouts().implicitlyWait(10,TimeUnit.SECONDS);driver.get("https://the-internet.herokuapp.com/upload");//we want to import selenium-snapshot file.
driver.findElement(By.id("file-upload")).sendKeys("selenium-snapshot.jpg");driver.findElement(By.id("file-submit")).submit();if(driver.getPageSource().contains("File Uploaded!")){System.out.println("file uploaded");}else{System.out.println("file not uploaded");}driver.quit();}}
fromseleniumimportwebdriverfromwebdriver_manager.chromeimportChromeDriverManagerdriver=webdriver.Chrome(ChromeDriverManager().install())driver.implicitly_wait(10)driver.get("https://the-internet.herokuapp.com/upload");driver.find_element(By.ID,"file-upload").send_keys("selenium-snapshot.jpg")driver.find_element(By.ID,"file-submit").submit()if(driver.page_source.find("File Uploaded!")):print("file upload success")else:print("file upload not successful")driver.quit()

require'selenium-webdriver'driver=Selenium::WebDriver.for:chromedriver.get("https://the-internet.herokuapp.com/upload")driver.find_element(:id,"file-upload").send_keys("selenium-snapshot.jpg")driver.find_element(:id,"file-submit").submit()ifdriver.page_source().include?"File Uploaded!"puts"file upload success"elseputs"file upload not successful"end
import{Builder,By}from"selenium-webdriver"letdriver=awaitnewBuilder().forBrowser('chrome').build()awaitdriver.get("https://the-internet.herokuapp.com/upload");awaitdriver.findElement(By.id("file-upload")).sendKeys("selenium-snapshot.jpg")awaitdriver.findElement(By.id("file-submit")).submit()driver.getPageSource().then(result=>{if(result.indexOf("File Uploaded!")){console.log("file upload success")}else{console.log("file upload not successful")}})

So the above example code helps to understand
how we can upload a file using Selenium.
To work on a web element using Selenium, we need to first locate it on the web page.
Selenium provides us above mentioned ways, using which we can locate element on the
page. To understand and create locator we will use the following HTML snippet.
<html><body><style>.information{background-color:white;color:black;padding:10px;}</style><h2>Contact Selenium</h2><formaction="/action_page.php"><inputtype="radio"name="gender"value="m"/>Male <inputtype="radio"name="gender"value="f"/>Female <br><br><labelfor="fname">First name:</label><br><inputclass="information"type="text"id="fname"name="fname"value="Jane"><br><br><labelfor="lname">Last name:</label><br><inputclass="information"type="text"id="lname"name="lname"value="Doe"><br><br><labelfor="newsletter">Newsletter:</label><inputtype="checkbox"name="newsletter"value="1"/><br><br><inputtype="submit"value="Submit"></form><p>To know more about Selenium, visit the official page
<ahref ="www.selenium.dev">Selenium Official Page</a></p></body></html>
class name
The HTML page web element can have attribute class. We can see an example in the
above shown HTML snippet. We can identify these elements using the class name locator
available in Selenium.
CSS is the language used to style HTML pages. We can use css selector locator strategy
to identify the element on the page. If the element has an id, we create the locator
as css = #id. Otherwise the format we follow is css =[attribute=value] .
Let us see an example from above HTML snippet. We will create locator for First Name
textbox, using css.
We can use the ID attribute available with element in a web page to locate it.
Generally the ID property should be unique for a element on the web page.
We will identify the Last Name field using it.
We can use the NAME attribute available with element in a web page to locate it.
Generally the NAME property should be unique for a element on the web page.
We will identify the Newsletter checkbox using it.
If the element we want to locate is a link, we can use the link text locator
to identify it on the web page. The link text is the text displayed of the link.
In the HTML snippet shared, we have a link available, lets see how will we locate it.
WebDriverdriver=newChromeDriver();driver.findElement(By.linkText("Selenium Official Page"));
driver=webdriver.Chrome()driver.find_element(By.LINK_TEXT,"Selenium Official Page")
vardriver=newChromeDriver();driver.FindElement(By.LinkText("Selenium Official Page"));
driver=Selenium::WebDriver.for:chromedriver.find_element(link_text:'Selenium Official Page')
letdriver=awaitnewBuilder().forBrowser('chrome').build();constloc=awaitdriver.findElement(By.linkText('Selenium Official Page'));
valdriver=ChromeDriver()valloc:WebElement=driver.findElement(By.linkText("Selenium Official Page"))
partial link text
If the element we want to locate is a link, we can use the partial link text locator
to identify it on the web page. The link text is the text displayed of the link.
We can pass partial text as value.
In the HTML snippet shared, we have a link available, lets see how will we locate it.
We can use the HTML TAG itself as a locator to identify the web element on the page.
From the above HTML snippet shared, lets identify the link, using its html tag “a”.
A HTML document can be considered as a XML document, and then we can use xpath
which will be the path traversed to reach the element of interest to locate the element.
The XPath could be absolute xpath, which is created from the root of the document.
Example - /html/form/input[1]. This will return the male radio button.
Or the xpath could be relative. Example- //input[@name=‘fname’]. This will return the
first name text box. Let us create locator for female radio button using xpath.
Selenium 4 introduces Relative Locators (previously
called as Friendly Locators). These locators are helpful when it is not easy to construct a locator for
the desired element, but easy to describe spatially where the element is in relation to an element that does have
an easily constructed locator.
How it works
Selenium uses the JavaScript function
getBoundingClientRect()
to determine the size and position of elements on the page, and can use this information to locate neighboring elements.
find the relative elements.
Relative locator methods can take as the argument for the point of origin, either a previously located element reference,
or another locator. In these examples we’ll be using locators only, but you could swap the locator in the final method with
an element object and it will work the same.
Let us consider the below example for understanding the relative locators.
Available relative locators
Above
If the email text field element is not easily identifiable for some reason, but the password text field element is,
we can locate the text field element using the fact that it is an “input” element “above” the password element.
If the password text field element is not easily identifiable for some reason, but the email text field element is,
we can locate the text field element using the fact that it is an “input” element “below” the email element.
If the cancel button is not easily identifiable for some reason, but the submit button element is,
we can locate the cancel button element using the fact that it is a “button” element to the “left of” the submit element.
If the submit button is not easily identifiable for some reason, but the cancel button element is,
we can locate the submit button element using the fact that it is a “button” element “to the right of” the cancel element.
If the relative positioning is not obvious, or it varies based on window size, you can use the near method to
identify an element that is at most 50px away from the provided locator.
One great use case for this is to work with a form element that doesn’t have an easily constructed locator,
but its associated input label element does.
You can also chain locators if needed. Sometimes the element is most easily identified as being both above/below one element and right/left of another.
These methods are designed to closely emulate a user’s experience, so,
unlike the Actions API, it attempts to perform two things
before attempting the specified action.
If it determines the element is outside the viewport, it
scrolls the element into view, specifically
it will align the bottom of the element with the bottom of the viewport.
It ensures the element is interactable
before taking the action. This could mean that the scrolling was unsuccessful, or that the
element is not otherwise displayed. Determining if an element is displayed on a page was too difficult to
define directly in the webdriver specification,
so Selenium sends an execute command with a JavaScript atom that checks for things that would keep
the element from being displayed. If it determines an element is not in the viewport, not displayed, not
keyboard-interactable, or not
pointer-interactable,
it returns an element not interactable error.
The element send keys command
types the provided keys into an editable element.
Typically, this means an element is an input element of a form with a text type or an element
with a content-editable attribute. If it is not editable,
an invalid element state error is returned.
Here is the list of
possible keystrokes that WebDriver Supports.

Clear
The element clear command resets the content of an element.
This requires an element to be editable,
and resettable. Typically,
this means an element is an input element of a form with a text type or an element
with acontent-editable attribute. If these conditions are not met,
an invalid element state error is returned.

This method is used to check if the connected Element is
displayed on a webpage. Returns a Boolean value,
True if the connected element is displayed in the current
browsing context else returns false.
This functionality is mentioned in, but not defined by
the w3c specification due to the
impossibility of covering all potential conditions.
As such, Selenium cannot expect drivers to implement
this functionality directly, and now relies on
executing a large JavaScript function directly.
This function makes many approximations about an element’s
nature and relationship in the tree to return a value.

Web applications can enable a public key-based authentication mechanism known as Web Authentication to authenticate users in a passwordless manner.
Web Authentication defines APIs that allows a user to create a public-key credential and register it with an authenticator.
An authenticator can be a hardware device or a software entity that stores user’s public-key credentials and retrieves them on request.
As the name suggests, Virtual Authenticator emulates such authenticators for testing.
Virtual Authenticator Options
A Virtual Authenticatior has a set of properties.
These properties are mapped as VirtualAuthenticatorOptions in the Selenium bindings.
A low-level interface for providing virtualized device input actions to the web browser.
In addition to the high-level element interactions,
the Actions API provides granular control over
exactly what designated input devices can do. Selenium provides an interface for 3 kinds of input sources:
a key input for keyboard devices, a pointer input for a mouse, pen or touch devices,
and wheel inputs for scroll wheel devices (introduced in Selenium 4.2).
Selenium allows you to construct individual action commands assigned to specific
inputs and chain them together and call the associated perform method to execute them all at once.
Action Builder
In the move from the legacy JSON Wire Protocol to the new W3C WebDriver Protocol,
the low level building blocks of actions became especially detailed. It is extremely
powerful, but each input device has a number of ways to use it and if you need to
manage more than one device, you are responsible for ensuring proper synchronization between them.
Thankfully, you likely do not need to learn how to use the low level commands directly, since
almost everything you might want to do has been given a convenience method that combines the
lower level commands for you. These are all documented in
keyboard, mouse, pen, and wheel pages.
Pause
Pointer movements and Wheel scrolling allow the user to set a duration for the action, but sometimes you just need
to wait a beat between actions for things to work correctly.
An important thing to note is that the driver remembers the state of all the input
items throughout a session. Even if you create a new instance of an actions class, the depressed keys and
the location of the pointer will be in whatever state a previously performed action left them.
There is a special method to release all currently depressed keys and pointer buttons.
This method is implemented differently in each of the languages because
it does not get executed with the perform method.
A representation of any key input device for interacting with a web page.
There are only 2 actions that can be accomplished with a keyboard:
pressing down on a key, and releasing a pressed key.
In addition to supporting ASCII characters, each keyboard key has
a representation that can be pressed or released in designated sequences.
Keys
In addition to the keys represented by regular unicode,
unicode values have been assigned to other keyboard keys for use with Selenium.
Each language has its own way to reference these keys; the full list can be found
here.
This is a convenience method in the Actions API that combines keyDown and keyUp commands in one action.
Executing this command differs slightly from using the element method, but
primarily this gets used when needing to type multiple characters in the middle of other actions.
Here’s an example of using all of the above methods to conduct a copy / paste action.
Note that the key to use for this operation will be different depending on if it is a Mac OS or not.
This code will end up with the text: SeleniumSelenium!
A representation of any pointer device for interacting with a web page.
There are only 3 actions that can be accomplished with a mouse:
pressing down on a button, releasing a pressed button, and moving the mouse.
Selenium provides convenience methods that combine these actions in the most common ways.
Click and hold
This method combines moving the mouse to the center of an element with pressing the left mouse button.
This is useful for focusing a specific element:
There are a total of 5 defined buttons for a Mouse:
0 — Left Button (the default)
1 — Middle Button (currently unsupported)
2 — Right Button
3 — X1 (Back) Button
4 — X2 (Forward) Button
Context Click
This method combines moving to the center of an element with pressing and releasing the right mouse button (button 2).
This is otherwise known as “right-clicking”:
This method moves the mouse to the in-view center point of the element.
This is otherwise known as “hovering.”
Note that the element must be in the viewport or else the command will error.
These methods first move the mouse to the designated origin and then
by the number of pixels in the provided offset.
Note that the position of the mouse must be in the viewport or else the command will error.
Offset from Element
This method moves the mouse to the in-view center point of the element,
then moves by the provided offset.
This method moves the mouse from its current position by the offset provided by the user.
If the mouse has not previously been moved, the position will be in the upper left
corner of the viewport.
Note that the pointer position does not change when the page is scrolled.
Note that the first argument X specifies to move right when positive, while the second argument
Y specifies to move down when positive. So moveByOffset(30, -10) moves right 30 and up 10 from
the current mouse position.
A Pen is a type of pointer input that has most of the same behavior as a mouse, but can
also have event properties unique to a stylus. Additionally, while a mouse
has 5 buttons, a pen has 3 equivalent button states:
0 — Touch Contact (the default; equivalent to a left click)
2 — Barrel Button (equivalent to a right click)
5 — Eraser Button (currently unsupported by drivers)
This is the most common scenario. Unlike traditional click and send keys methods,
the actions class does not automatically scroll the target element into view,
so this method will need to be used if elements are not already inside the viewport.
This method takes a web element as the sole argument.
Regardless of whether the element is above or below the current viewscreen,
the viewport will be scrolled so the bottom of the element is at the bottom of the screen.
This is the second most common scenario for scrolling. Pass in an delta x and a delta y value for how much to scroll
in the right and down directions. Negative values represent left and up, respectively.
This scenario is effectively a combination of the above two methods.
To execute this use the “Scroll From” method, which takes 3 arguments.
The first represents the origination point, which we designate as the element,
and the second two are the delta x and delta y values.
If the element is out of the viewport,
it will be scrolled to the bottom of the screen, then the page will be scrolled by the provided
delta x and delta y values.
This scenario is used when you need to scroll only a portion of the screen, and it is outside the viewport.
Or is inside the viewport and the portion of the screen that must be scrolled
is a known offset away from a specific element.
This uses the “Scroll From” method again, and in addition to specifying the element,
an offset is specified to indicate the origin point of the scroll. The offset is
calculated from the center of the provided element.
If the element is out of the viewport,
it first will be scrolled to the bottom of the screen, then the origin of the scroll will be determined
by adding the offset to the coordinates of the center of the element, and finally
the page will be scrolled by the provided delta x and delta y values.
Note that if the offset from the center of the element falls outside of the viewport,
it will result in an exception.
Scroll from a offset of origin (element) by given amount
The final scenario is used when you need to scroll only a portion of the screen,
and it is already inside the viewport.
This uses the “Scroll From” method again, but the viewport is designated instead
of an element. An offset is specified from the upper left corner of the
current viewport. After the origin point is determined,
the page will be scrolled by the provided delta x and delta y values.
Note that if the offset from the upper left corner of the viewport falls outside of the screen,
it will result in an exception.

Selenium is working with browser vendors to create the
WebDriver BiDirectional Protocol
as a means to provide a stable, cross-browser API that uses the bidirectional
functionality useful for both browser automation generally and testing specifically.
Before now, users seeking this functionality have had to rely on
with all of its frustrations and limitations.
The traditional WebDriver model of strict request/response commands will be supplemented
with the ability to stream events from the user agent to the controlling software via WebSockets,
better matching the evented nature of the browser DOM.
As it is not a good idea to tie your tests to a specific version of any browser, the
Selenium project recommends using WebDriver BiDi wherever possible.
However, until the specification is complete there are many useful things that
CDP (Chrome DevTools Protocol) offers. To help keep your tests independent
and portable, Selenium offers some useful helper classes as well. At the
moment, they use the CDP, but soon it could be done using WebDriver BiDi.

Register Basic Auth
Some applications make use of browser authentication to secure pages.
With Selenium, you can automate the input of basic auth credentials whenever they arise.

While Selenium 4 provides direct access to the Chrome DevTools Protocol (CDP), it is
highly encouraged that you use the WebDriver Bidi APIs instead.
Many browsers provide “DevTools” – a set of tools that are integrated with the browser that
developers can use to debug web apps and explore the performance of their pages. Google Chrome’s
DevTools make use of a protocol called the Chrome DevTools Protocol (or “CDP” for short).
As the name suggests, this is not designed for testing, nor to have a stable API, so functionality
is highly dependent on the version of the browser.
WebDriver Bidi is the next generation of the W3C WebDriver protocol and aims to provide a stable API
implemented by all browsers, but it’s not yet complete. Until it is, Selenium provides access to
the CDP for those browsers that implement it (such as Google Chrome, or Microsoft Edge, and
Firefox), allowing you to enhance your tests in interesting ways. Some examples of what you can
do with it are given below.
Emulate Geo Location
Some applications have different features and functionalities across different
locations. Automating such applications is difficult because it is hard to emulate
the geo-locations in the browser using Selenium. But with the help of Devtools,
we can easily emulate them. Below code snippet demonstrates that.

Support classes provide optional higher level features.
The core libraries of Selenium try to be low level and non-opinionated.
The Support classes in each language provide opinionated wrappers for common interactions
that may be used to simplify some behaviors.
The Select object will now give you a series of commands
that allow you to interact with a <select> element.
If you are using Java or .NET make sure that you’ve properly required the support package
in your code. See the full code from GitHub in any of the examples below.
Note that this class only works for HTML elements select and option.
It is possible to design drop-downs with JavaScript overlays using div or li,
and this class will not work for those.
Types
Select methods may behave differently depending on which type of <select> element is being worked with.
Single select
This is the standard drop-down object where one and only one option may be selected.
<selectname="selectomatic"><optionselected="selected"id="non_multi_option"value="one">One</option><optionvalue="two">Two</option><optionvalue="four">Four</option><optionvalue="still learning how to count, apparently">Still learning how to count, apparently</option></select>
Multiple select
This select list allows selecting and deselecting more than one option at a time.
This only applies to <select> elements with the multiple attribute.
First locate a <select> element, then use it to initialize a Select object.
Note that as of Selenium 4.5, you can’t create a Select object if the <select> element is disabled.
Get a list of selected options in the <select> element. For a standard select list
this will only be a list with one element, for a multiple select list it can contain
zero or many elements.
The Select class provides three ways to select an option.
Note that for multiple select type Select lists, you can repeat these methods
for each element you want to select.

It is not always obvious the root cause of errors in Selenium.
The most common Selenium-related error is a result of poor synchronization.
Read about Waiting Strategies. If you aren’t sure if it
is a synchronization strategy you can try temporarily hard coding a large sleep
where you see the issue, and you’ll know if adding an explicit wait can help.
Note that many errors that get reported to the project are actually caused by
issues in the underlying drivers that Selenium sends the commands to. You can rule
out a driver problem by executing the command in multiple browsers.

for ways get assistance.

10.1 - Understanding Common Errors
How to get deal with various problems in your Selenium code.
Invalid Selector Exception
CSS and XPath Selectors are sometimes difficult to get correct.
Likely Cause
The CSS or XPath selector you are trying to use has invalid characters or an invalid query.
An element goes stale when it was previously located, but can not be currently accessed.
Elements do not get relocated automatically; the driver creates a reference ID for the element and
has a particular place it expects to find it in the DOM. If it can not find the element
in the current DOM, any action using that element will result in this exception.
Common Causes
This can happen when:
You have refreshed the page, or the DOM of the page has dynamically changed.
You have navigated to a different page.
You have switched to another window or into or out of a frame or iframe.
Common Solutions
The DOM has changed
When the page is refreshed or items on the page have moved around, there is still
an element with the desired locator on the page, it is just no longer accessible
by the element object being used, and the element must be relocated before it can be used again.
This is often done in one of two ways:
Always relocate the element every time you go to use it. The likelihood of
the element going stale in the microseconds between locating and using the element
is small, though possible. The downside is that this is not the most efficient approach,
especially when running on a remote grid.
Wrap the Web Element with another object that stores the locator, and caches the
located Selenium element. When taking actions with this wrapped object, you can
attempt to use the cached object if previously located, and if it is stale, exception
can be caught, the element relocated with the stored locator, and the method re-tried.
This is more efficient, but it can cause problems if the locator you’re using
references a different element (and not the one you want) after the page has changed.
The Context has changed
Element objects are stored for a given context, so if you move to a different context —
like a different window or a different frame or iframe — the element reference will
still be valid, but will be temporarily inaccessible. In this scenario, it won’t
help to relocate the element, because it doesn’t exist in the current context.
To fix this, you need to make sure to switch back to the correct context before using the element.
The Page has changed
This scenario is when you haven’t just changed contexts, you have navigated to another page
and have destroyed the context in which the element was located.
You can’t just relocate it from the current context,
and you can’t switch back to an active context where it is valid. If this is the reason
for your error, you must both navigate back to the correct location and relocate it.
10.2 - Logging Selenium commands
Getting information about Selenium execution.
Each language adopts a distinctly different approach to logging information about the activity
of the program.
Ruby
Ruby uses a custom implementation of the default Logger class with some interesting additional features.
Logger output
By default, logs are sent to the console in stdout.
if you want to store the logs in a file, add this to your code:
The basic levels for the Ruby logger are: :debug, :info, :warn, :error, :fatal
Selenium uses :info and :debug similar to “verbose” and “very verbose”, so the default
is :warn.
To change the level of the logger:
Selenium::WebDriver.logger.level=:fatal
WARN
Warnings include everything we want users to be aware of by default. This is mostly used
for deprecations. For various reasons, Selenium project does not follow standard Semantic Versioning practices.
Our policy is to mark things as deprecated for 3 releases and then remove them.
As such, Ruby logs deprecations as warnings, specifying what is changing, what needs to be
used instead. It may include additional messages, and always includes an ID.
For example:
2022-12-24 16:07:09 WARN Selenium [DEPRECATION] [:jwp_caps] `Capabilities#version=` is deprecated. Use `Capabilities#browser_version=` instead.
Because these items can get annoying, we’ve provided an easy way to turn them off.
To turn off a specific warning, set the ID to ignore:
This is where the most useful information gets logged. Selenium logs the endpoints and payloads
sent to and received from the driver or server. This is a great way to see what Selenium is actually
doing under the hood, and can be used to determine if it is Selenium code or driver code that
is causing a problem. (Unfortunately, we can’t blame the driver if Selenium is sending incorrect syntax).
DEBUG
This is less useful information where we log things about the servers and the sockets, and header information, etc.
Debug mode is set if either $DEBUG is true or ENV['DEBUG'] has a value.
