Why this is considered a error? I really don't see the error there. I'm doing env bootstrapping and I still have no code, so obviously I have no test, what doesn't mean I should not configure karma to run.

You should at least have a setting to consider this expected behavior, but I really think it should not be considered error by default.

I see this typically when there's an error in your JavaScript - like a compilation error

I've seen this with an empty test suite too, but I prefer to view my test results in the debug.html - see karma-mocha for example on how to set that up.

Seeing this here also before adding any tests on karma 0.13.19. Agree that this should not be an error (which will cause builds to fail). If I add tests than everything works as expected.

This already done in the master branch and will go out with the next release https://github.com/karma-runner/karma/pull/1796

I have used the karma init and setup a simple test and still get this error.

I resolved my issue by adding in karma-typescript

$ npm i karma-typescript -D

However, I would be open to better ways to resolving this.

Well you could write your in JavaScript, that would also resolve this. Or precompile ts to js.

You are testing in a browser. Browsers run JavaScript. Ergo you have to compile your TypeScript to JavaScript or write in JavaScript in the first place.
