Iterating through the testing parameters

[Miroslav999]

Hello, guys! I've come up with an idea, maybe not a new one. Enter the test parameters into the tests and perform a complete iteration of the parameters when running the tests. This question concerns the design of tests, and it would be nice in the framework itself to be able to generate combinations of parameters for scenarios.

Demo project https://github.com/Miroslav999/Example_test_parameters/tree/master . We have three parameters in the class test2.my.param.MyArgumentsProvider, and when we run the test test2.my.param.MyTestClass.testWithArgumentsSource, we get all possible combinations for them. If the feature is interesting, then I could develop it, for example, creating combinations based on the pairwise principle testing or introduce rules that would determine the conditions under which the number of scenarios should be reduced.

Have you seen @CartesianTest from JUnit Pioneer? What you describe seems to be very close to that.

This has indeed been brought up several times.

Just search for "cartesian" in closed issues.

https://github.com/junit-team/junit-framework/issues?q=sort%3Aupdated-desc%20is%3Aissue%20state%3Aclosed%20cartesian

As @scordio mentioned, JUnit Pioneer offers @CartesianTest to address that need.
