Description

• Added multiple test classes for parallel browser instance testing.

  • MultipleInstanceParallelTest tests background color changes using multiple browser instances.
  • SingleInstanceCookieParallelTest tests background color changes using a single browser instance with user context.

Tests

MultipleInstanceParallelTest.java Add tests for multiple browser instance parallel testing  examples/java/src/test/java/dev/selenium/bidirectional/webdriver_bidi/user_context/MultipleInstanceParallelTest.java Added tests for background color changes using multiple browser instances. Utilized FirefoxDriver with private browsing mode. Verified color changes to blue, green, and default white. Included setup and cleanup methods for WebDriver lifecycle management. +92/-0    SingleInstanceCookieParallelTest.java Add tests for single browser instance with user context    examples/java/src/test/java/dev/selenium/bidirectional/webdriver_bidi/user_context/SingleInstanceCookieParallelTest.java Added tests for background color changes using a single browser instance. Demonstrated user context creation and browsing context management. Verified color changes to blue, green, and default white. Used WebDriver BiDi API for advanced interactions. +124/-0  SingleInstanceCookieParallelGridTest.java Add Selenium Grid tests for single browser instance            examples/java/src/test/java/dev/selenium/bidirectional/webdriver_bidi/user_context/SingleInstanceCookieParallelGridTest.java Added tests for background color changes on Selenium Grid. Demonstrated user context and browsing context creation on a remote WebDriver. Verified color changes to blue, green, and default white. Included @Ignore annotations for tests, likely for future enablement. +139/-0

⏱️ Estimated effort to review: 2 🔵🔵⚪⚪⚪

🧪 PR contains tests

🔒 No security concerns identified

⚡ Recommended focus areas for review Ignored Tests All test methods in this class are annotated with @ignore but the class itself is not. Consider adding a comment explaining why these tests are ignored or remove the annotation if they should be executed. @Ignore @Test void canSwitchToBlue() { context.navigate("https://www.selenium.dev/selenium/web/cookie-background.html", ReadinessState.COMPLETE); RemoteValue value = context.locateNode(Locator.xpath("/html/body/button[1]")); Input inputModule = new Input(driver); Actions actions = new Actions(driver); RemoteWebElement element = new RemoteWebElement(); element.setId(value.getSharedId().get()); actions.moveToElement(element).click(); inputModule.perform(context.getId(), actions.getSequences()); value = context.locateNode(Locator.xpath("/html/body")); NodeProperties properties = (NodeProperties) value.getValue().get(); String bgColor = properties.getAttributes().get().get("style"); Assertions.assertEquals(bgColor, "background-color: lightblue;"); System.out.println( Thread.currentThread().getName() + " " + Thread.currentThread().getStackTrace()[1] .getMethodName() + " => executed successfully"); } @Ignore @Test void canSwitchToGreen() { context.navigate("https://www.selenium.dev/selenium/web/cookie-background.html", ReadinessState.COMPLETE); RemoteValue value = context.locateNode(Locator.xpath("/html/body")); NodeProperties properties = (NodeProperties) value.getValue().get(); String bgColor = properties.getAttributes().get().get("style"); Assertions.assertEquals(bgColor, "background-color: white;"); value = context.locateNode(Locator.xpath("/html/body/button[2]")); Input inputModule = new Input(driver); Actions actions = new Actions(driver); RemoteWebElement element = new RemoteWebElement(); element.setId(value.getSharedId().get()); actions.moveToElement(element).click(); inputModule.perform(context.getId(), actions.getSequences()); value = context.locateNode(Locator.xpath("/html/body")); properties = (NodeProperties) value.getValue().get(); bgColor = properties.getAttributes().get().get("style"); Assertions.assertEquals(bgColor, "background-color: lightgreen;"); System.out.println( Thread.currentThread().getName() + " " + Thread.currentThread().getStackTrace()[1] .getMethodName() + " => executed successfully"); } @Ignore @Test void canHaveTheDefaultBackgroundColor() { context.navigate("https://www.selenium.dev/selenium/web/cookie-background.html", ReadinessState.COMPLETE); RemoteValue value = context.locateNode(Locator.xpath("/html/body")); NodeProperties properties = (NodeProperties) value.getValue().get(); String bgColor = properties.getAttributes().get().get("style"); Assertions.assertEquals(bgColor, "background-color: white;"); System.out.println( Thread.currentThread().getName() + " " + Thread.currentThread().getStackTrace()[1] .getMethodName() + " => executed successfully"); } Hardcoded URL The test uses a hardcoded URL for the Selenium Grid (http://localhost:4444). Consider making this configurable through a property or environment variable to improve flexibility. new RemoteWebDriver( new URL("http://localhost:4444"), options, false);

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
General	Use non-deprecated BiDi enablement Replace the deprecated setCapability("webSocketUrl", true) with options.enableBiDi() which is the recommended way to enable BiDi protocol support in Selenium 4. examples/java/src/test/java/dev/selenium/bidirectional/webdriver_bidi/user_context/MultipleInstanceParallelTest.java [19-21] FirefoxOptions options = new FirefoxOptions(); -options.setCapability("webSocketUrl", true); +options.enableBiDi(); options.addArguments("-private"); Apply this suggestion Suggestion importance[1-10]: 8 __ Why: The suggestion correctly identifies the use of a deprecated method setCapability("webSocketUrl", true) and proposes replacing it with the recommended options.enableBiDi() method. This is an important improvement for code maintainability and future compatibility with Selenium 4.	Medium
