Question

I am writing tests and I have heard some people saying to use self.assertFalse rather than assert False. Why is this and are there any advantages to be had?

Answer 1

assert False throws an exception without useful logging information. The test had an error.

self.assertFalse() throws a test failure exception with test failure information like a message and a test name.

There’s a difference between an error — test could not even run — and a failure — test code worked but produced the wrong answer.

Errors are a serious problem with your code.

Failures are just failures that need to be fixed.
