Subject: [PATCH] tests: add helper function to autodetect CI environments
|
|
|
|
Sadly there is no standarized way to check if we're running in some
|
|
CI environment. So let's try to gather the heuristics in one helper
|
|
function.
|
|
|
|
Loosely cherry-picked from 4eb0c875f8825199a829ddc597874915fbee0a84.
