Hi everyone! It would be nice to have an approval testing <http://approvaltests.com/> plugin for pytest, but it seems there's no perfect solution at the moment. A quick google search gave me this <https://github.com/approvals/ApprovalTests.Python> and this <https://gist.github.com/npryce/9c4dc2e0ea7eaf6e27fc>, but that's kind of far from ideal.
What I would like to have is the ability to mark a test as approval test and then the framework would compare the return value of the test function to the approved output, produce error diffs, allow approving new output, etc. It would also play nice with fixtures, parametrization and other pytest features so that a separate approved result would be generated for each test item, stored in a file with some useful name and all of this would be transparent for the developer. A diffing tool for approving the outputs could be specified via configuration parameter or an environment variable. Does this sounds like something that you have seen? If not, I will probably try to build it (most likely from scratch, since not much of the functionality of ApprovalTest.Python would be useful here and I feel like I would struggle against their approval naming code) and would appreciate any advice. Cheers, Vasily
