By default, jest fails if no tests were found. But when we use runner: 'groups' the process exits with status 0 which is unexpected and may lead to situations when we don't notice that something doesn't work, e.g. like https://github.com/eugene-manuilov/jest-runner-groups/issues/42 :
> test() { jest --group=$1 --verbose=false --runInBand --logHeapUsage --detectOpenHandles; }; test "unit"
