19 What does cross-browser testing verify?

20 Which Selenium Grid endpoint is commonly used to check the Grid's current status?

21 A team wants every developer and CI server to use the same Selenium and TestNG library versions. Which Maven feature most directly supports this requirement?

22 A Maven project stores TestNG tests under src/test/java. Which plugin normally discovers and runs those tests during the test phase?

23 The build reports that org.openqa.selenium.WebDriver cannot be found while compiling test classes. Selenium is absent from pom.xml. What is the appropriate correction?

24 A login test must run with five username-password combinations without duplicating the test method. Which TestNG feature is most suitable?

25 A TestNG listener needs to capture a screenshot only when a test fails. Which callback and result check should it use?

26 A TestNG suite should run test classes concurrently while methods within each class remain grouped in that class's execution. Which suite configuration is appropriate?

27 A test uses SoftAssert to verify the page title, user name, and account balance. What must be called after the checks so that collected failures affect the test result?

28 A browser must be created before every test method and closed after every test method, even if a test fails. Which annotation pair best matches this lifecycle?

29 A checkout test sometimes fails because it clicks the Pay button before the button becomes enabled. Which change best improves the test case?

30 A successful login redirects users to URLs such as /dashboard?session=abc123. Which assertion is most robust for confirming the destination?

31 A local test currently creates ChromeDriver directly. To send the same test to Selenium Grid, which WebDriver implementation should normally replace it?

32 Several session requests arrive when every matching Grid node is busy. Which Grid component holds the requests until capacity becomes available?

33 After a session is created, Grid must determine which node owns that session when later commands arrive. Which component maintains this mapping?

34 Which Selenium Grid component matches a requested browser capability with an available node slot?

35 A developer needs a complete Grid on one machine for a small test suite with minimal setup. Which startup mode is most appropriate?

36 A test method receives browser as a TestNG parameter and must create matching Grid capabilities. What is the best script design?

37 A TestNG test submitOrder depends on login, and login fails. With the dependency configured through dependsOnMethods, what is the expected result for submitOrder?

38 Parallel Chrome and Firefox tests occasionally send commands to each other's browser sessions because they share a static WebDriver field. Which change best addresses the problem?

39 A monitoring service must check whether Selenium Grid is ready to accept sessions without opening a browser. Which endpoint should it query?

40 A Grid node has eight CPU cores, but browser memory usage requires limiting it to two concurrent sessions. Which node setting should be customized?

41 A Maven Selenium project contains src/main/java, src/test/java, and src/test/resources. A TestNG suite XML file must be available only during test execution and must not be packaged in the production JAR. Where should it be placed?

42 A project directly declares Selenium version 4.18.1. Another direct dependency transitively brings Selenium version 4.15.0. Both versions occur at the same dependency depth. Which Maven rule normally determines the selected version?

43 A TestNG suite works through an IDE but mvn test reports that no tests were executed. The classes are named CheckoutFlow.java, and Surefire has no custom includes or suite XML configuration. What is the most direct explanation?

44 A TestNG test method uses @DataProvider(parallel = true) and receives 40 data rows. The test stores its WebDriver in one shared instance field. Failures show sessions navigating to pages intended for other rows. Which design best addresses the root cause?

45 A TestNG test must pass when an IllegalArgumentException is thrown only if its message starts with Invalid account:. Which annotation usage expresses both requirements through the TestNG API?

46 A testng.xml suite is configured with parallel="methods" and thread-count="4". It contains one test class whose methods share a mutable instance field. Which statement is correct?

47 A superclass defines @BeforeClass openBase() and @AfterClass closeBase(). Its subclass defines @BeforeClass openChild() and @AfterClass closeChild(). Assuming all configuration methods succeed, which order does TestNG use?

48 A test uses a TestNG SoftAssert, performs five checks, and then returns without calling assertAll(). Two checks failed. What result should be expected?

49 A checkout test fails intermittently because it clicks a button immediately after an overlay disappears visually, while the element is still not clickable. Which test design most directly models the required state?

50 A page displays currency as $1,234.50, while the service returns the numeric value 1234.5. Which assertion strategy is most robust?

51 A RemoteWebDriver request specifies browserName=chrome and platformName=LINUX. The Grid has idle Chrome nodes, but all advertise platformName=WINDOWS. What should happen under normal capability matching?

52 In a fully distributed Selenium Grid, a new WebDriver session request reaches the Router. Which interaction correctly describes how a matching execution slot is obtained?

53 After a session is created, Grid must route later commands containing that session ID to the Node hosting it. Which component maintains the session-to-Node URI mapping?

54 A distributed Grid Node starts successfully but never appears as available in the Distributor. Browser drivers are installed correctly. The Node and Distributor were configured with different Event Bus publish and subscribe addresses. What is the most likely cause?

55 A test must run against a remote Grid and request Chrome without depending on the local machine's ChromeDriver executable. Which construction is appropriate?

56 A TestNG @BeforeMethod creates a remote driver, but session creation occasionally throws an exception. The @AfterMethod calls driver.quit() without checking whether assignment succeeded, obscuring the original failure with a NullPointerException. Which teardown is most appropriate?

57 A parallel TestNG suite creates Chrome and Firefox sessions from a shared mutable MutableCapabilities object. Each thread changes browserName immediately before session creation. What is the best correction?

58 A monitoring process needs a lightweight JSON response indicating whether Selenium Grid is ready to accept sessions. Which endpoint is intended for this purpose?

59 An operations dashboard needs selected Grid data such as node details and session information without repeatedly scraping the Grid UI. Which Selenium Grid endpoint is designed for structured, field-specific queries?

60 A Node has 16 CPU cores, so its general max-sessions is configured as 16. However, a resource-intensive browser stereotype must never run more than two concurrent sessions. Which configuration approach directly enforces that browser-specific limit?
