…uild is complete This change is inspired by karma-runner/karma-chrome-launcher#154 (comment) which blocks Karma from launching the browsers until the compilation is complete. This is needed especially for large applications when using code-coverage where otherwise the users would have to fine-tune several Karma timeouts such as `captureTimeout` for various environments. Closes #22495

What if Karma fails? Will this callback still be executed or do we need a separate error handler to reject the Promise?

I think you meant if webpack fails, yeah this will always be executed.
We don’t want to reject this promise because otherwise Karma will fail to start.
