TestNG is a testing framework for Java that supports various annotations to define test methods and their behavior.

• TestNG is used for unit, functional, and integration testing

• Annotations like @Test, @BeforeTest, @AfterTest, etc. are used to define test methods and their behavior

• TestNG allows grouping of test methods and prioritizing their execution

• TestNG also supports data-driven testing and parallel test execution

• Exam...read more

TestNg.xml file is important for configuring and executing TestNG tests.

• TestNg.xml file allows us to configure test suites, test cases, and test data.

• It helps in grouping and prioritizing tests, setting up dependencies, and parallel execution.

• We can also specify test parameters, listeners, and reporting options in the TestNg.xml file.

• Example:

• Example:

• Example:

Implicit wait is a global wait applied to all elements, while explicit wait is a wait applied to a specific element.

• Implicit wait is set once and applied to all elements in the script

• Explicit wait is set for a specific element and waits for a certain condition to be met

• Implicit wait is set using the 'driver.manage().timeouts().implicitlyWait()' method

• Explicit wait is set using the 'WebDriverWait' class and 'ExpectedCon...read more

Screenshots can be captured using built-in tools or third-party software.
