I think I know what's going on there. When drilling down into tests and subtests, only those matching the filter are shown. Clearing the filter things look a bit different in the directories you mentioned: https://wpt.fyi/results/ambient-light?label=master&label=experimental&product=chrome%5Btaskcluster%5D&product=firefox%5Btaskcluster%5D&product=safari%5Bazure%5D&aligned https://wpt.fyi/results/bluetooth?label=master&label=experimental&product=chrome%5Btaskcluster%5D&product=firefox%5Btaskcluster%5D&product=safari%5Bazure%5D&aligned
In particular for idlharness.js tests some subtests will pass because they're preconditions for the real tests. There will also be tests that check that something doesn't work, which will pass even if the feature is entirely unsupported if "not working" results in the same thing, e.g. throwing an exception. Sometimes tests can be tweaked to fail if the feature is unsupported. Drilling down into a directory somewhat at random and clearing filters, it does look like this is legit: https://wpt.fyi/results/fetch/api/cors?label=master&label=experimental&product=chrome%5Btaskcluster%5D&product=firefox%5Btaskcluster%5D&product=safari%5Bazure%5D&aligned On Mon, Feb 25, 2019 at 8:31 PM Maciej Stachowiak <m...@apple.com> wrote: > > Neat. > > I see some obvious areas for focus, where Safari fails lots of tests that > the other browser don’t. > > For context, I tried looking at this view, which shows all tests that > Safari and Firefox pass with Safari results regardless of result: > > https://wpt.fyi/results/?label=master&label=experimental&product=chrome%5Btaskcluster%5D&product=firefox%5Btaskcluster%5D&product=safari%5Bazure%5D&aligned&q=%28chrome%3Apass%7Cchrome%3Aok%29+%28firefox%3Apass%7Cfirefox%3Aok%29 > <https://wpt.fyi/results/?label=master&label=experimental&product=chrome[taskcluster]&product=firefox[taskcluster]&product=safari[azure]&aligned&q=(chrome:pass%7Cchrome:ok)+(firefox:pass%7Cfirefox:ok)> > > I noticed some puzzling results there: Safari passes all the ambient-light > and bluetooth tests that Chrome and Firefox do, despite not supporting > these standards at all.
