Was this taken from the Crowdstrike repo?
Was there even tests?
Yup, and they're run on an estimated 8.5 million test machines
Testing in prod is a power move honestly. Rock star-level
Yeah, but I think apparently the tests that "could" have caught it relied on mocks which basically rendered it useless in those cases.
Ah yes. The unintended consequences of mandated code coverage without reviewing the tests. If you can mock the shit out of the test conditions to always give you exactly the answer you want, what's the point of the test?
It's like being allowed to write your own final exam, and all you need to pass the exam is 90% correct on the questions you wrote for yourself.
Unit tests, yes, but you don't only do unit tests. Integration and e2e tests still exist.
And this is why mocks are bad…
