$ME: PR does not include changes in the 'tests' directory
|

|
|
Please write a regression test for what you're fixing. Even if it
|
|
seems trivial or obvious, try to add a test that will prevent
|
|
regressions.
|
|
|
|
If your change is minor, feel free to piggyback on already-written
|
|
tests, possibly just adding a small step to a similar existing test.
|
|
Every second counts in CI.
|
|
|
|
If your commit really, truly does not need tests, you can proceed
|
|
by asking a repo maintainer to set the '$OVERRIDE_LABEL' github label.
|
|
This will only be done when there's no reasonable alternative.
