What is the correct order for actual and expected in pytest?

This question gives the order assertEqual(expected, actual), albeit for the unittest package.

But Pycharm, with pytest, prints out "Expected:..." and "Actual..." based on the order actual==expected.

This is confusing. What is the correct ordering for pytest? The source code and online documentation do not say.

(I note also that JUnit and TestNG disagree on this.)

Solution

  • BDFL doesn't like actual/expected terminology and the docs were specifically changed to address this.

    If your tooling is expecting arguments in a certain order, then I suppose the most correct thing to do would be to consistently do what works for your tooling.
