We're using Cypress and Cucumber. I have a lot of tests as they're going through a lot of combinations on the webpage, so I end up with about 1,600 single steps.
To be able to do a quick smoke test I have separated those tests into 40 scenarios and marked them with tags, usually just running the first important tag on deployment and the full suite only nightly.
But I noticed, after the tests of the "good" tag are done (which takes about 2 minutes), Cypress still hangs for about 10 more minutes. Running in headed mode, I found out that is is still going through the whole list of 1,600 tests, just counting most of them as "pending". It manages to count about 2 to 3 tests per second. Chrome is running at 100% CPU during that counting, and this process is even part of the generated video file.
Here's an example of the output after the tests. Completing the 115 tests took about 2 minutes, the rest was spent in counting the tests where the tag did not match.
$ npx cypress run --browser chrome --env 'TAGS=@quicktest'
│ Tests: 1561 │
│ Passing: 115 │
│ Failing: 0 │
│ Pending: 1444 │
│ Skipped: 0 │
│ Screenshots: 0 │
│ Video: true │
│ Duration: 11 minutes, 42 seconds │
Is there any way to completely ignore and skip the tests where the scenario tag does not match?
You can try setting omitFiltered to true, using eg.
$ npx cypress run --browser chrome --env 'TAGS=@quicktest,omitFiltered=true'
If you can provide a reproducible example, then I might be able to investigate the reason for the slow countdown.
