Fix pipeline tests
# What does this PR do?

Changes in #18392 broke tests in the pipelines, this PR fixes them.
> Why weren't these ran on the original PR ?

Cause the common test files used not only have the tester for each pipeline, not tests of its own, so is not triggered by the `tests_fetcher`. Will fix in this PR as well.<|||||>_The documentation is not available anymore as the PR was closed or merged._
