First, you need to import the python module where your test is defined.
Eg, if you have two files: `tc/tests_a.py` and `tc/tests_b.py`.  If
tests_a defines a testcase `do_foo_bar()`, you can call it in tests_b
like this:

	# tc/tests_b.py
	import tbot
	import tests_a


	@tbot.testcase
	def call_foo() -> None:
	    tests_a.do_foo_bar()

(If the testcase you want to call is in the same source file, just call
 it like a normal function)

I don't have an example repo yet, unfortunately :/ It is on my
ToDo list, I will add one soon(TM)!
