Parameterization

What is parameterization

• To pass external test data to the testcases.

Why do we need to use it?

• To test the same functionality with different set of data or for running the same test with different configurations.

How to do parametrization?

• Using TestNg annotation based on the type of data

Types of Parameterization:

There are two ways by which we can achieve parameterization in TestNG

• Static Parameterization
• Dynamic Parameterization

1. Static parameterization:

• To pass the data through xml file
• Can be achieved through @Parameters annotation in testmethod
• Syntax:

  @Parameters({"url", "username","Password")}

2. Dynamic parameterization

What is Dynamic parameterization?

• To pass external test data to the testcases.

Why do we need to use it?

• To test the same functionality with different set of data or for running the same test with different configurations.

How to do parametrization?

• Using TestNg annotation based on the type of data

Steps to achieve dynamic parametrization

• Step:1 Create a normal method with return type of String[][]
• Step:2 Declare and assign the value to the 2D Dimensional array
• Step:3 Add @DataProvider annotation on top of the method
• Step:4 Add dataProvider attribute the @Test Method
• Step:5 Add arguments to @test method to pass data from the DataProvider Method
