Selenium Webdriver

By the end of this Selenium WebDriver tutorial, you will be in a better position to know what is selenium grid, know how to run Selenium WebDriver tests on local Selenium Grid and cloud Selenium Grid.

Each version of selenium-webdriver will support the latest semver-minorversion of the LTS and stable Node releases. All semver-major &semver-minor versions between the LTS and stable release will have "besteffort" support. Following a Selenium release, any semver-minor Node releaseswill also have "best effort" support. Releases older than the latest LTS,semver-major releases, and all unstable release branches (e.g. "v.Next")are considered strictly unsupported.

The selenium.webdriver module provides all the WebDriver implementations.Currently supported WebDriver implementations are Firefox, Chrome, IE andRemote. The Keys class provide keys in the keyboard like RETURN, F1, ALT etc.The By class is used to locate elements within a document.

The Ruby bindings for Selenium/WebDriver are available as the selenium-webdriver gem. The web page explains how to install the selenium-webdriver gem. If you're looking for a slightly higher level API built on the same technology, you may want to check out watir or capybara.

Home: Docs:selenium package APIDev: PyPI: IRC:#selenium channel on LiberaChatSeveral browsers/drivers are supported (Firefox, Chrome, Internet Explorer), as well as the Remote protocol.

In this article, we will teach you how to install your own automation environment and run your own tests using Selenium/WebDriver and a testing library such as selenium-webdriver for Node. We will also look at how to integrate your local testing environment with commercial tools like the ones discussed in the previous article.

Note: It is still a good idea to follow these steps even if you previously installed selenium-webdriver and downloaded the browser drivers. You should make sure that everything is up-to-date.

Next, you need to download the relevant drivers to allow WebDriver to control the browsers you want to test. You can find details of where to get them from on the selenium-webdriver page (see the table in the first section.) Obviously, some of the browsers are OS-specific, but we're going to stick with Firefox and Chrome, as they are available across all the main OSes.

You should see an instance of Firefox automatically open up! Google should automatically be loaded in a tab, "webdriver" should be entered in the search box, and the search button will be clicked. WebDriver will then wait for 2 seconds; the document title is then accessed, and if it is "webdriver - Google Search", we will return a message to claim the test is passed. WebDriver will then close down the Firefox instance and stop.

Let's have a look at a few key features of the webdriver syntax. For more complete details, you should consult the selenium-webdriver JavaScript API reference for a detailed reference and the Selenium main documentation's Selenium WebDriver, which contain multiple examples to learn from written in different languages.

Next, you need to create a new instance of a driver, using the new webdriver.Builder() constructor. This needs to have the forBrowser() method chained onto it to specify what browser you want to test with this builder, and the build() method to actually build it (see the Builder class reference for detailed information on these features).

You can submit key presses that can't be represented by normal characters using properties of the webdriver.Key object. For example, above we used this construct to tab out of the form input before submitting it:

You should see an instance of Firefox automatically open up! Google should automatically be loaded in a tab, \"webdriver\" should be entered in the search box, and the search button will be clicked. WebDriver will then wait for 2 seconds; the document title is then accessed, and if it is \"webdriver - Google Search\", we will return a message to claim the test is passed. WebDriver will then close down the Firefox instance and stop.

The name Selenium comes from a joke made by Huggins in an email, mocking a competitor named Mercury, saying that you can cure mercury poisoning by taking selenium supplements. The others that received the email took the name and ran with it.[7]

Selenium Remote Control (RC) is a server, written in Java, that accepts commands for the browser via HTTP. RC makes it possible to write automated tests for a web application in any programming language, which allows for better integration of Selenium in existing unit test frameworks. To make writing tests easier, Selenium project currently provides client drivers for PHP, Python, Ruby, .NET, Perl and Java. The Java driver can also be used with JavaScript (via the Rhino engine). An instance of selenium RC server is needed to launch html test case - which means that the port should be different for each parallel run.[citation needed] However, for Java/PHP test case only one Selenium RC instance needs to be running continuously.[13]

Selenium RC served as the flagship testing framework of the entire project of selenium for a long-standing time. And significantly[editorializing] Selenium RC is the first and foremost automated web testing tool that enabled users to adopt their preferred programming language. [14][15]

To check if the driver is installed properly, launch a new Command Prompt window and enter the name of the webdriver. For example, if you are using ChromeDriver, type in chromedriver and press Enter.

quit() is a webdriver command which calls the driver.dispose method, which in turn closes all the browser windows and terminates the WebDriver session. If we do not use quit() at the end of the program, the WebDriver session will not be closed properly, and the files will not be cleared off memory. This may result in memory leak errors.

Optional ff_profile_dir is the path to the Firefox profile directory if you wish to overwrite the default profile Selenium uses. Notice that prior to SeleniumLibrary 3.0, the library contained its own profile that was used by default. The ff_profile_dir can also be an instance of the selenium.webdriver.FirefoxProfile . As a third option, it is possible to use FirefoxProfile methods and attributes to define the profile using methods and attributes in the same way as with options argument. Example: It is possible to use FirefoxProfile set_preference to define different profile settings. See options argument documentation in below how to handle backslash escaping.

Using alias to decide, is the new browser opened is new in SeleniumLibrary 4.0. The options and service_log_path are new in SeleniumLibrary 4.0. Support for ff_profile_dir accepting an instance of the selenium.webdriver.FirefoxProfile and support defining FirefoxProfile with methods and attributes are new in SeleniumLibrary 4.0.

Locators are a collection of factory functions for creating locator instances. Locators find DOM elements, which can be passed to functions such as $webDriver.findElement. Call them through $selenium.By.

The reason for this is that the Firefox Driver also supports runningtests written in pure Javascript. Normally, this would be an extremelydifficult thing to support: the tests are running in the context ofthe browser's Javascript security sandbox, and so may not do a rangeof things that are useful in tests, such as traveling between domainsor uploading files. The WebDriver Firefox extension, however, providesan escape hatch from the sandbox. It announces its presence by addinga webdriver property to the document element. The WebDriverJavascript API uses this as an indicator that it can add JSONserialized command objects as the value of a command property onthe document element, fire a custom webdriverCommand event andthen listen for a webdriverResponse event on the same element tobe notified that the response property has been set.

Behind the scenes, there is a DOM messenger, waiting for thewebdriverCommand this reads the serialized JSON object and callsthe execute method on the command processor. This time, thecallback is one that simply sets the response attribute on thedocument element and then fires the expected webdriverResponseevent. 59ce067264
