Robust regression test execution reports show how important they are and the value they bring to the product, even more so if they are automated and run continuously. A regression plan is made up of all the tests aimed at validating the implementations and business flows continuously; as the application grows, so will the regression plan, while other plans, such as smoke, that check the main business flows will remain unchanged as long as these flows exist.
In order to have a correct process at the testing level, the corresponding tests of the functionalities at the code level must be carried out first through Unit and API tests, while the business tests (smoke, regression) will be carried out at a later stage to continue increasing the value of the tests carried out on the application.
