Should be configured manually (with token):

[command]/bin/bash --noprofile --norc /home/vsts/work/_temp/3e5c0a43-effc-4bd1-9192-d036a83503e2.sh
Not on Travis or CircleCI. You have to provide either repo_token in .coveralls.yml or set the COVERALLS_REPO_TOKEN env var.

I think migrating to Azure should be considered as a last resort when there's literally no way to fix the original problem. To me it doesn't seem to be the case, at least for now.

As I mentioned in this comment #114 (comment), sometimes we need an ability to run e2e tests locally, and I don't think we should have e2e tests running for more than 50 minutes.

Before making this change I would kindly ask you to investigate what exactly takes so much time. You could start by looking into single model and comparing it to other languages.

And thanks for your constant initiative to make m2cgen better, we really appreciate your effort!

Unfortunately, I can only confirm that PowerShell is quite slow. Tests for all models run significant amount of time, and there is no "one test that takes the most time of 50 minutes". I guess it's specific to PowerShell and nothing can be done with it.

OK, I think I'd better close this PR for now. Anyway, you can take my proposed config from the Files changed tab any moment you need it in the future.
