Angular 2 Karma tests have started to fail can't capture browser

This seems like a project setup problem in someway. This was working previously. I don't have the knowledge that these error messages help me to start. Does anyone have some advice on where to start diagnosing the problem?

If running karma test from your IDE (for example, IntelliJ IDEA) and your solution doesn't build/has lint errors, karma seems to not connect and just hang.

Run your tests with something like ng test and get that working before running from your IDE.

After upgrading my Angular lib versions, my Karma tests too started to fail which led me to the this question. After verifying the @angular/cli versions, now 1.1.2, match between global and the local project the following may also be required:

Update your src/tsconfig.spec.json by adding "dom" to the lib array:

"lib": ["es2016", "dom"],

I was able to move forward past the problem, but not identify the root cause by doing the following.

  • sync angular/cli project and global versions to latest: 1.0.4
  • rm node_modules which I had done before, but reading this. I was missing npm cache clean
  • npm install

Thanks @MatthewDaly for the useful suggestions and questions.
