  • [ X ] bug report

What is the current behavior?
When a test (shard) disconnects, that shard is restarted but it only runs 1 more test in that set of tests giving it a false SUCCESS.

More info
We had tests that had been failing on our CI but we didn't know it because the build was being reported as successful. Checking in new tests caused the shards to change revealing failures for tests that were previously being skipped

The logs below are at the time when one of the browsers disconnects and it's restarted with a single test.

And it looks like it was replaced with a duplicate of the shard with 543 (the above logs show the duplicate entry for that shard.

  • If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem

We have not been able to create a minimal demo

  • What is the expected behavior?

When a shard disconnects, it either runs the entire, or restarts from the test that had a problem.

  • Please tell us about your environment:
  • version: 0.3.1
  • Browser: [Headless Chrome ]
  • Language: [TypeScript]
  • Other information (e.g. detailed explanation, stacktraces, related issues, suggestions how to fix, links for us to have context, eg. stackoverflow, gitter, etc)

I can provide a full log of different runs if it helps. I can also try any suggestions. I understand this is not the best bug submission but it does look like there's a problem when restarting a shard after the browser disconnects.

Hi - I have setup karma-parallel on our test suite as well. Approx 2700 tests. On the first run the sharding is working great and it has massively decreased our suite run times. However as above we are getting false positives when the runner disconnects from chrome. It will run again but not run the tests in the shard that disconnected. Unfortunately this means we can't use this day to day at the moment.

We are running 500 tests and it has reduced our time as well but the browser disconnect issue is preventing us from running this within our CI/CD Pipeline. :(

We are running 16k tests and got the same problem as well (concurrency 2-3, chunks 200-500).
Some thoughts: we used karma-parallel for last two years in ci pipeline with our own custom webpack config for huge hybrid angular application. Now we moved to ng-cli build configuration and faced this issue. Maybe ng-cli is the root of evil.
UPD: forget it. The problem was in our docker container. Now everything works as expected.
