Current version build not passing

[bartekleon]

It seems that the current version has some issue (node-sass not found) and so it says on GitHub that your build is failing

[nicojs]

Yep, working on it in my spare time. We're having problems with the cleanup after a run. Sometimes the cleanup results in an error, producing an exit code 1. This can be reproduced with our perf tests on linux.

Thanks for reporting 🙇

[davesag]

@nicojs yes I am seeing the cleanup error you mention. Only on Linux though and not on macOS. See https://circleci.com/gh/davesag/amqp-simple-pub-sub/272 for example.

The solution appears to be to set the number of test runners to 2.

maxConcurrentTestRunners: 2

This appears to relate to #1525

[nicojs]

Most definitely related to #1525. This might sound silly, but I'm actually waiting on TS3.5 release later this month, as that hopefully solves a compile error in the async dispose branch. At least, the compile error seems to be solved with 3.5-rc.

TypeScript seems to have problems with typed-inject. See this PR for more info: nicojs/typed-inject#7

[davesag]

Yet another reason to avoid TypeScript. :-)

[nicojs]

Yeah, I can understand the sentiment. However, typed-inject is an extreme example of type-safety. It makes our code more type-safe than Java with Spring or C# with .NET core.

I wouldn't want to maintain sug a big code base as Stryker without type-safety.

[davesag]

I was writing Javascript in 1995, well before I ever heard of Java and a decade before C# existed, so I've learned to love type-flexibility and a pure functional style of coding.
