Our AUT is integrated into multiple downstream applications where it uses parent application 's API to communicate and get data. It is important to test the sample API call in multiple applications. We thought it is a good candidate to automate.
Example: Downstream application will post a request to the parent about User permissions and API should respond with valid and corresponding permission details. AUT has around more than 100 types of permission which combinations come around 250+. In this case, manual testing is a hard/dull process.
Solution with Ready API: Created a test case with all the combinations in the data-driven approach and It will execute. This way automation covered all different combinations and validated every single combination.
This gives us a lot of meaning on the ROI and making a solid statement on the quality of the product. When it comes to this kind of scenarios then Automation is the best and "must-have" one.
