Parameterization in Selenium: In the most cases you will come across the scenario where the business logic requires a hugely varying number of test cases. Basically parameterized tests allow to developer to run the same over and over again using different values.
Test NG lets you pass parameters
directly to your test method in two different ways:
- With testng.xml
- With Data Provider
We define the simple parameters in the testng.xml file. When you need to pass complex parameters or parameters that need to be created from java (complex object ,object read from the properties file or database etc.) in such cases parameters can be pass using Data Providet.
