Pytest - custom output of test results

Question

I want to completely custom tests results output. In unittest I can implement my own test runner by example of unittest.TextTestRunner. How can I do the same in pytest?

Take a look at how pytest-custom-report plugin does it for inspiration. — wim

As described in "Writing plugins" section of pytest documentation, you'll need to work with pytest hooks:

pytest implements all aspects of configuration, collection, running and reporting by calling well specified hooks of the following plugins:

py.test code snippets
pycon tutorial session (it also goes through using hooks)

Seems like hooks allows to just modify information that will be represented in some standard way, but how to completely redesign results report? For example I want to write it to CSV?

Yeah, that's not like a simple task to do with pytest. Have you considered using nose?

Gill, that's certainly possible, as far as I know. For an example, look at Mozilla Web QA's pytest module, which formats reports as HTML. A lot of the logic would be the same as formatting them as CSV (though IMO using standard JUnit XML would be a lot better...) github.com/davehunt/pytest-mozwebqa/tree/master/pytest_mozwebqa
