Parameters of test methods in TestNg

TestNG is a popular testing framework for Java that allows you to define and run tests in a flexible and organized manner. Test methods in TestNG are the actual test cases that you want to run. These test methods can have various parameters and attributes that you can use to customize the test execution. Here are some of the key parameters and attributes you can use with TestNG test methods:

1. @Test annotation: You use the @Test annotation to mark a method as a test method. You can also provide various attributes to customize the behavior of the test method. Some commonly used attributes include:
   • priority: Specifies the order in which the test methods should run.
   • enabled: If set to false, the test method will be skipped.
   • dataProvider and dataProviderClass: Used for data-driven testing by specifying the data provider method and class.
   • groups: Assigns the test method to one or more groups, which can be used for test grouping and execution control.
2. Data Providers: TestNG allows you to use data providers to parameterize your test methods. You can create methods that provide test data, and then specify the data provider method using the dataProvider attribute in the @Test annotation.
3. Parameters: You can pass parameters to your test methods using the @Parameters annotation and defining these parameters in your testng.xml configuration file

DependsOnMethods: You can specify dependencies between test methods using the dependsOnMethods attribute in the @Test annotation. This ensures that one test method runs only after the specified methods have successfully executed.

ITestContext: You can use the ITestContext parameter to access information about the test context, suite, and other attributes within your test methods. This can be useful for dynamically configuring or reporting test results.

These are some of the key parameters and attributes you can use with TestNG test methods. TestNG provides a wide range of options for configuring and customizing your test cases, allowing you to create comprehensive and organized test suites.
