Some of your tests did a full page reload - error when running Jasmine tests

Question

I'm running into an issue where when I run my tests on Jasmine, I get this error below. The problem is, it seems to happen when I try to execute a certain amount of tests. It doesn't seem to be tied to a particular test, as if I comment out some, the tests pass. If I uncomment some tests, the error appears. If I comment out ones that were uncommented before, they all pass again. (ie if I have red, green, blue and orange test and it fails, I comment out orange and blue it passes, then I uncomment blue and orange it fails again, but if I comment out red and green it passes again).

Chrome 41.0.2272 (Mac OS X 10.10.1) ERROR Some of your tests did a full page reload! Chrome 41.0.2272 (Mac OS X 10.10.1): Executed 16 of 29 (1 FAILED) ERROR (0.108 secs / 0.092 secs)

I'm stumped as to what is going on. The more tests I add, that's when this becomes an issue. Has anyone encountered this before? I have no idea what could be causing it, as nothing in any of my tests do any kind of redirection, and they all pass universally on another persons machine.

Answer 1

In my case the problem was that in my source code I had code directly setting the href on the location object, like window.location.href = 'somewhere';

In my specs I set up a onbeforeunload listener that just returns a string instead of allowing the redirect to take place:

beforeAll(() => {   window.onbeforeunload = () => 'Oh no!'; });

Make sure that your tests are properly isolating all modules under test with mocks/spies. The behavior you are seeing says to me that your tests are not truly running in isolation - they are changing some state somewhere that will trigger a reload.
