Allow HTML summary to only show failed tests.

[cvanelteren]

The docs state

Summary reports can also be produced when generating baseline images and hash libraries. The summaries will be written to the results directory. When generating a HTML summary, the --mpl-results-always option is automatically applied. Therefore images for passing tests will also be shown.

However, I believe it would be beneficial to extend the option to only show failed tests. Is this already possible or could this be added to the pytest-mpl?

Hi @cvanelteren, the results can be filtered to only failing tests within the HTML page itself. You should also be able to access the filtered page directly with a query string in the URL, e.g, https://pytest-mpl.readthedocs.io/en/stable/sample/test_html_images_only/fig_comparison.html?f=overall-failed

Is that sufficient for your use case?
