How do I use DataProvider TestNG?

How To Use DataProvider In TestNG?

  1. Note: You need to import the DataProvider in TestNG by adding the line import org.
  2. Note: Unlike parameters in TestNG, the dataproviders can be run directly through the test case file.
  3. Import Required: import java.lang.reflect.Method;

Can we pass parameters to DataProvider in TestNG?

However, TestNG parameters enable us to pass the values only once per execution cycle. To overcome this, we can use DataProvider in TestNG that allows us to pass multiple parameters to a single test in a single execution. Using DataProviders, we can easily pass multiple values to a test in just one execution cycle.

What is DataProvider annotation in TestNG and why you use it?

@DataProvider annotation helps us write data-driven test cases. The @DataProvider annotation enables us to run a test method multiple times by passing different data-sets. The name of this data provider.

What is mocking in Java testing?

Mocking is a technique of unit testing a class, where we mock an external dependency in order to test our classes and methods. When unit tests are written well with mocks, they would not have any external dependencies and will not fail when external stuff changes.

What is Mockito mock?

Mockito is a mocking framework, JAVA-based library that is used for effective unit testing of JAVA applications. Mockito is used to mock interfaces so that a dummy functionality can be added to a mock interface that can be used in unit testing.

How is DataProvider useful for your framework?

DataProvider helps with data-driven test cases that carry the same methods but can be run multiple times with different data sets. It also helps in providing complex parameters to the test methods.

How do I retrieve data from DataProvider?

What is the difference between DataProvider and parameter in TestNG?
