Hi, I've been following this thread for a while.
I'm trying to bring in a test strategy in my team to test a number of data pipelines before production. I have watched Lars' presentation and find it great. However I'm debating whether unit tests are worth the effort if there are good job-level and pipeline-level tests. Does anybody have any experiences benefitting from unit-tests in such a case?
