Say I have

tests
  BUILD
  - A
     - BUILD
     - test_m1.py
  - B
     - BUILD
     - test_m2.py

if I want to run all tests under the

tests

directory when there's a change to a particular target in the sources, do I need to update every

python_tests

target recursively in the

tests

(or create a macro that would declare that dependency) or is there a way to do this somehow from the

tests/BUILD

only? It would have been possible to use a recursive pattern in the

python_tests

(e.g.

sources=["*/**/test_*.py"]

, but because there is a

BUILD

file in each directory, the tests are already owned.
