streams

edit

WPT coverage of the tests of streams at the revision 5602b0f210e3. The tests link to their results in the browsers on wpt.fyi. The tentative tests (experimental features) and the reftests are listed separately from the stable tests.

Group	Passing	Tests	Disabled	Pass rate
Stable	70	85	4	86%
Tentative	1	4	0	25%
Reftests	0	0	0	–
All	71	89	4	84%

Failure reasons

The tests that do not pass (failing or disabled), by kind of reason. A test with several reasons counts once per kind.

NOT IMPLEMENTED: 14
TEST RUNNER: 14
