TestTemplateInvocationContext should allow to set a testSourceUri

[ThomasReinhardt]

Overview

Align TestTemplateInvocationContext with the capabilities of DynamicTest to allow for a custom testSourceUri. Right now DynamicTests created by a @TestFactory do not participate in the normal lifecycle with @BeforeEach etc.

A good solution often is to use @TestTemplate, but that misses the custom testSourceUri.

The change would be minimal and mostly consists of carrying the URI (or rather a TestSource instance) through a couple of contexts and descriptors. I can provide a working pull request if so desired.

Deliverables

• new method in TestTemplateInvocationContext: default Optional<URI> getTestSourceUri()

@ThomasReinhardt Im interested in working on this issue!

I'm not the one to decide. If I understand correctly we are asked to wait for comments from the core junit team.

Notes for team discussion:

• URI sources for dynamic tests were introduced in 54f11a2 as part of DynamicTest should be able to provide tags and source information to TestDescriptor #1178 and the same rationale would apply here.

• First and foremost, both TestTag and TestSource reside in the junit-platform-engine artifact and are therefore not visible from the JUnit Jupiter programming model.
  by @sbrannen in #1178_

So a @Nullable URI testSourceUri would be prefered.

@mpkorstanje That's fine with me. So I @RafaelMagalhaes22407372 is good to go?

[RafaelMagalhaes22407372]

@ThomasReinhardt Im good to go!! Already working on it.

@RafaelMagalhaes22407372 you have everything you need? Because I basically have all the classes available that need to be touched...

[RafaelMagalhaes22407372]

@ThomasReinhardt Im exploring and looking. I think im headed in the right way. I'll keep in touch.
