# selenium-webdriver Selenium is a browser automation library. Most often used for testing web-applications, Selenium may be used for any task that requires automating interaction with the browser. ## Installation Selenium may be installed via npm with npm install selenium-webdriver You will need to download additional components to work with each of the major browsers. The drivers for Chrome, Firefox, and Microsoft's IE and Edge web browsers are all standalone executables that should be placed on your system [PATH]. Apple's safaridriver (v10 and above) can be found at the following path – /usr/bin/safaridriver. To enable automation on safari, you need to run command `safaridriver --enable`. | Browser | Component | | :---------------- | :------------------------------- | | Chrome | [chromedriver(.exe)][chrome] | | Internet Explorer | [IEDriverServer.exe][release] | | Edge | [MicrosoftWebDriver.msi][edge] | | Firefox | [geckodriver(.exe)][geckodriver] | | Opera | [operadriver(.exe)][operadriver] | | Safari | [safaridriver] | ## Usage The sample below and others are included in the `example` directory. You may also find the tests for selenium-webdriver informative. ```javascript const { Builder, Browser, By, Key, until } = require('selenium-webdriver') ;(async function example() { let driver = await new Builder().forBrowser(Browser.FIREFOX).build() try { await driver.get('https://www.google.com/ncr') await driver.findElement(By.name('q')).sendKeys('webdriver', Key.RETURN) await driver.wait(until.titleIs('webdriver - Google Search'), 1000) } finally { await driver.quit() } })() ``` ### Using the Builder API The `Builder` class is your one-stop shop for configuring new WebDriver instances. Rather than clutter your code with branches for the various browsers, the builder lets you set all options in one flow. When you call `Builder#build()`, all options irrelevant to the selected browser are dropped: ```javascript const webdriver = require('selenium-webdriver') const chrome = require('selenium-webdriver/chrome') const firefox = require('selenium-webdriver/firefox') let driver = new webdriver.Builder() .forBrowser(webdriver.Browser.FIREFOX) .setChromeOptions(/* ... */) .setFirefoxOptions(/* ... */) .build() ``` Why would you want to configure options irrelevant to the target browser? The `Builder`'s API defines your _default_ configuration. You can change the target browser at runtime through the `SELENIUM_BROWSER` environment variable. For example, the `example/google_search.js` script is configured to run against Firefox. You can run the example against other browsers just by changing the runtime environment # cd node_modules/selenium-webdriver node example/google_search SELENIUM_BROWSER=chrome node example/google_search SELENIUM_BROWSER=safari node example/google_search ### The Standalone Selenium Server The standalone Selenium Server acts as a proxy between your script and the browser-specific drivers. The server may be used when running locally, but it's not recommend as it introduces an extra hop for each request and will slow things down. The server is required, however, to use a browser on a remote host (most browser drivers, like the IEDriverServer, do not accept remote connections). To use the Selenium Server, you will need to install the [JDK](http://www.oracle.com/technetwork/java/javase/downloads/index.html) and download the latest server from [Selenium][release]. Once downloaded, run the server with java -jar selenium-server-4.27.0.jar standalone You may configure your tests to run against a remote server through the Builder API: ```javascript let driver = new webdriver.Builder() .forBrowser(webdriver.Browser.FIREFOX) .usingServer('http://localhost:4444/wd/hub') .build() ``` Or change the Builder's configuration at runtime with the `SELENIUM_REMOTE_URL` environment variable: SELENIUM_REMOTE_URL="http://localhost:4444/wd/hub" node script.js You can experiment with these options using the `example/google_search.js` script provided with `selenium-webdriver`. ## Documentation API documentation is available online from the [Selenium project][api]. Additional resources include - the #selenium channel on freenode IRC - the [selenium-users@googlegroups.com][users] list - [SeleniumHQ](https://selenium.dev/documentation/) documentation ## Contributing Contributions are accepted either through [GitHub][gh] pull requests or patches via the [Selenium issue tracker][issues]. ## Node Support Policy Each version of selenium-webdriver will support the latest _semver-minor_ version of the [LTS] and stable Node releases. All _semver-major_ & _semver-minor_ versions between the LTS and stable release will have "best effort" support. Following a Selenium release, any _semver-minor_ Node releases will 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. For example, suppose the current LTS and stable releases are v22.13.0 and v23.6.0, respectively. Then a Selenium release would have the following support levels: | Version | Support | | :--------: | :-----------: | | <= 16.20.2 | _unsupported_ | | 16.20.2 | supported | | 18.8.0 | supported | | >= 22.13.0 | best effort | | v.Next | _unsupported_ | ### Support Level Definitions - _supported:_ A selenium-webdriver release will be API compatible with the platform API, without the use of runtime flags. - _best effort:_ Bugs will be investigated as time permits. API compatibility is only guaranteed where required by a _supported_ release. This effectively means the adoption of new JS features, such as ES2015 modules, will depend on what is supported in Node's LTS. - _unsupported:_ Bug submissions will be closed as will-not-fix and API compatibility is not guaranteed. ### Projected Support Schedule If Node releases a new [LTS] each October and a new major version every 6 months, the support window for selenium-webdriver will be roughly: | Release | Status | END-OF-LIFE | | :-----: | :-------------: | :---------: | | v18.x | Maintenance LTS | 2025-04-30 | | v19.x | End-of-Life | 2023-06-01 | | v20.x | Maintenance LTS | 2026-04-30 | | v21.x | End-of-Life | 2024-06-01 | | V22.x | Active LTS | 2027-04-30 | | V23.x | Current | 2025-06-01 | ## Issues Please report any issues using the [Selenium issue tracker][issues]. When using the issue tracker - **Do** include a detailed description of the problem. - **Do** include a link to a [gist](http://gist.github.com/) with any interesting stack traces/logs (you may also attach these directly to the bug report). - **Do** include a [reduced test case][reduction]. Reporting "unable to find element on the page" is _not_ a valid report - there's nothing for us to look into. Expect your bug report to be closed if you do not provide enough information for us to investigate. - **Do not** use the issue tracker to submit basic help requests. All help inquiries should be directed to the [user forum][users] or #selenium IRC channel. - **Do not** post empty "I see this too" or "Any updates?" comments. These provide no additional information and clutter the log. - **Do not** report regressions on closed bugs as they are not actively monitored for updates (especially bugs that are >6 months old). Please open a new issue and reference the original bug in your report. ## License Licensed to the Software Freedom Conservancy (SFC) under one or more contributor license agreements.
