A quick guide on how to data seed via parameterized API requests. Parameterization is very important for automation testing. It helps you to iterate on input data with multiple data sets that make your scripts reusable and maintainable. In few scenarios, you can still manage with hard coded request but the same approach will not work out where sheer count of combinations is to be validated. By implementing the right solution, you can keep your code base and test data size at ideal range and still savor the benefits of optimal coverage.
