TestNG 面试题与答案
问题 21. Explain the use of the 'priority' attribute in the @Test annotation.
The 'priority' attribute in the @Test annotation allows you to specify the order in which test methods should be executed. Test methods with lower priority values are executed first.
问题 22. What is the purpose of the @Listeners annotation in TestNG?
The @Listeners annotation in TestNG is used to specify one or more listener classes that will be notified during the test execution. This allows you to implement custom behavior at various stages of the test lifecycle.
问题 23. Explain the use of the 'dependsOnGroups' attribute in TestNG.
The 'dependsOnGroups' attribute in TestNG allows you to specify groups that must be executed before the current test method. It establishes a dependency relationship between groups.
问题 24. What is the purpose of the 'timeOut' attribute in the @Test annotation?
The 'timeOut' attribute in the @Test annotation allows you to specify the maximum time (in milliseconds) that a test method should take to complete its execution. If the time exceeds this limit, the method is marked as a failure.
问题 25. Explain the concept of testng-failed.xml in TestNG.
The testng-failed.xml file in TestNG is automatically generated when a test run has failures. It contains only the failed test methods and can be used to rerun only the failed tests.
