On this forum, you will find various question about test parameters. Each time, the answer is to use the custom fields. In some cases, it can help. But when you have various kind of parameters, it become really difficult to handre. With what we have currently, a solution would be to create generic custom fields named parameter_1, parameter_2, parameter_3, parameter_x.
But it would pollute a lot the test cases view.
Here my proposition: add a parameters section in the test case view, beside Details, Test & Results, Defects and History. This new section will be a simple table, where each row contains a set of parameters.
API would have to be updated to handle update of this section. Test result would be associated to a parameters set.
What do you think?
