TaskTestBase should handle this I think.

Added a docstring -- this is used specifically to hydrate the run_before_task_types and run_after_task_types in self.invoke_tasks().

Should have addressed the comments above, and finally managed to get a green CI run! |

The run_before and run_after tasks look very important for correct usage of this class, but it's not clear to me what they would do (without reading the implementation of this class).

Added lots more documentation (and removed the previous docstrings)!

This helper method doesn't seem like it is specific to this class. You could probably pass in the dist_specs as a map, and return the created targets (which you could then pass to invoke_tasks). That would allow the method to move up to TestBase, and make it useful in more places.
The rest of the Task manipulation stuff could probably stay here.

| The values of `target_map` should themselves be a flat dict, which contains keyword arguments | ||
| fed into `self.make_target()`, along with a few special keys. Special keys are: | ||
| - 'key' (required -- used to index into the returned dict). |

Could this be an address, or address string?

It could default to that, actually -- the idea was to decouple accessing the target from within testing from its specific address so you could use a test class-specific shorthand.

It now defaults to the target address string!

Problem
We want to do #7128, which involves adding some more C/C++ unit testing. We would love to use some of the declarative task specification stuff we've added to the
python_dist()testing to do that.Solution
BuildLocalPythonDistributionsTestBaseintoDeclarativeTaskTestMixinintask_test_base.py.Result
A new interface for task unit testing (which can be extended to more than just v1 tasks) is available to other testing.
