When we see test runner in "commands" section of tox, we substitute it with our test runners so user may benefit from test trees. We also pass "offset" because test runners must use it as "parent node". Set "_jb_do_not_patch_test_runners" to disable this substitution (cherry picked from commit c7d469e1fed52f2d7fe3aec6d96b665c4aa80a4e) GitOrigin-RevId: b9eec43a6d26fecb72270b733266ef31989fec2c
