another day another bug: In one corner we have a beautifully crafted 500 line test which exqusitely mocks all it's dependencies.in the other corner a blatant bug on production.

I'm in the call and ask to reproduce the issue and much message-queuing and clicking begins.

I ask them to run the test, but the beautiful test doesn't reproduce the issue.

In 10 seconds I write an integration test for the specific class and reporoduce the issue and it's fixed minutes later.

the integration test features 1/10th of the code and delivers about 1000% more value*.

not only that but it's 5000% more maintainable*.

this isn't necessarily a rant about mocks (although I hate them so), but it is certainly a rant about inappropriate mocking.
