pytest-expect code now in a github repo

I’ve made a few changes to the pytest-expect fixture plugin.

  1. I’ve put the plugin code on github,
  2. It is re-arranged to be a plugin installable with pip. Although I don’t have it in pypi yet.
  3. I’ve modified the code to use pytest 2.7.0 @pytest.mark.hookwrapper.
  4. I incorporated Bruno’s feedback from the last post to allow both assert failures and expect failures to be reported in the same test.
  5. There’s a tests directory to test the plugin.

There’s still lots to do. But this is a decent start.

Instead of listing any code here, go check out the pytest-expect repository on github

Also, I’ve set up a pytest-expect page. Not much there yet, but I plan on hosting the documentation for this thing there.

pytest expect fixture plugin, iteration 1

This is the first iteration that implements ‘expect’ as a fixture.

This is really the third attempt at an ‘expect()’ implementation that allows multiple failures per test.

  1. First attempt was a general solution that works with any test framework, but with a slightly clunky API. The main problem with it was that it required the test to call a final ‘assert_expectations()’ from the test code. If you forgot to call that function, the failures weren’t reported.
  2. Second attempt was a pytest plugin implementation that eliminated the need for the ‘assert_expectations()’ call in the test because it was called automatically. I wasn’t thrilled with this solution. But it works.
  3. In the solution I’m presenting in this post, I’m moving all of the code into one file and implementing ‘expect’ as a pytest fixture.

pytest fixtures nuts and bolts

I’d like to wrap up this recent series of pytest fixture posts by presenting my version of some sort of reference.
Since this post is running a bit long, here are some links to the content buried in here.
