Try to not have too many or too few tests in one file. The simplest explanation of data-driven testing is this: data that is external to your functional tests is loaded and used to extend your automated test cases. My first interest in automated testing came in the form of unit tests. In data driven framework script will be separated from Data part, it means so if any changes happen we do not have to modify all the test cases.
