angular-cli: ng test ends with "Executed 0 of 0 ERROR"

I’m using Windows 10 (10.0.14388.0 (rs1_release.160709-1635)), node 6.9.1 and angular-cli 1.0.0-beta.18.

I created a new ng project with angular-cli and ran ng test. I got the following output:

λ ng test
23 10 2016 10:52:02.889:WARN [karma]: No captured browser, open http://localhost:9876/
23 10 2016 10:52:02.897:INFO [karma]: Karma v1.2.0 server started at http://localhost:9876/

Chrome 55.0.2883 (Windows 10 0.0.0): Executed 0 of 0 ERROR (0.003 secs / 0 secs)

I can’t see any actual error message from the command line or from Karma’s Chrome instance’s console.

UPDATE: Actually this might be related to the warning “No capture browser” even though browser seems to open just fine.

see @jtsom 's answer: In the karma.conf.js file, add: mime: { 'text/x-typescript': ['ts','tsx'] }, works for me.

mime: { ‘text/x-typescript’: [‘ts’,‘tsx’] }, works for me, thanks @penghuili

I still have the same error, and in my karma.conf.js I already have the mime defined

For anybody arriving here even though they don’t use Angular while searching for this error, adding mime: { 'text/x-typescript': ['ts','tsx'] } to karma.conf.js did indeed fix it for me when using a Chrome version of 55.

Guys, I’m having the same issue, but adding the mime it seems just to get worse: instead of getting “Executed 0 of 0 ERROR” I just get “Chrome 56.0.2924 (Windows 10 0.0.0) ERROR”. Anywan having a clue on what’s going on? Thanks!

Just wondering what the status on this is. I upgraded Chrome last night unaware of it and getting the following:

Chrome 55.0.2883 (Mac OS X 10.12.1): Executed 0 of 0 ERROR (0.003 secs / 0 secs)

results when running ng test

I had the same issue in Chrome version 56. Setting the mime fixed it as well.
