Flunk Your ExUnit Tests ❌

Today I got to use the flunk/1 function in an ExUnit test. I like everything about this function, from its name to its signature.

Here’s how we used it:

case result do
  "bad" ->
    flunk("Your result is bad, and you should feel bad.")

  "good" ->
    assert result_passes_other_tests(result)
end

It fit well into a helper function that should fail if my result ever comes back a certain way.
