Another common problem with unit testing is that the function being tested should actually be four different functions and the setup is so complex, it becomes more of an integration test on the wrong level.

Then the developer will say "unit testing is a pain in the ass, I rather do integration tests". But the problem is that the code being tested is calling out its problems through these tests.

i hear this often but i don’t think it’s true. sometimes a good integration test will do you more favour than a dozen of unit tests. also unit tests can be a pain in the ass as a bad integration test
