TestNG for Parameterized Testing in Java

TestNG is a popular and powerful testing framework for Java, widely used for automated testing in various applications. One of its notable features is support for parameterized testing, which allows you to run the same test method with different sets of input data.

Parameterized testing is useful when you want to test your code with multiple inputs or test cases, saving you time and effort. It helps ensure that your code works correctly under different scenarios.

TestNG provides the @DataProvider annotation to specify the data source for parameterized testing. The data source can be an array, a collection, or a method that returns an iterator or an iterable object.

Here is an example of parameterized testing using TestNG:

Step 1: Prepare Test Data

First, you need to define the test data. This can be done by creating a method that returns a two-dimensional array or a collection of objects representing different test cases.

Step 2: Define Test Method

Next, you need to write the test method that accepts parameters for input data. In the test method, you can perform assertions based on the input data.

Step 3: Use DataProvider Annotation

Finally, annotate the test method with the @DataProvider annotation, specifying the name of the method that provides the test data.

With TestNG, you can easily perform parameterized testing in Java and ensure your code is thoroughly tested with various inputs. It is a free and open source software, publicly available for testing.
