ERROR [compiler.karma-typescript] however Karma doesn't fail

[typeofweb]

Whenever there's a compilation error, eg:

ERROR [compiler.karma-typescript]: src/hello.component.ts(9,16): error TS2322: Type 'string' is not assignable to type 'void'.

Karma should fail too. Instead, it continues and tests may pass even if there are TypeScript compilation errors.

Is there any way to avoid this behaviour?

Example output:

16 11 2016 13:50:33.253:ERROR [compiler.karma-typescript]: src/hello.component.ts(9,16): error TS2322: Type 'string' is not assignable to type 'void'.

Hey @mmiszy, you can set noEmitOnError to true in either tsconfig.json or in the karma conf:

karmaTypescriptConfig: {
    compilerOptions: {
         noEmitOnError: true,
         //...
    },
    //...
}

This will make karma exit in quite a spectacular way, I've added this feature to the documentation!

Indeed it makes Karma exit. However what I wanted to achieve is for Karma not to quit, but just to report the error and keep on watching files for changes. Is it possible?

It doesn't seem like this will be easy to implement, Karma seems to be kind of "binary", it either runs the tests or it quits, it's discussed here in a somewhat similar issue: karma-runner/karma#550.
