JS Karma error: Some of your tests did a full page reload!

[alexgibson]

Description

Occasionally when I run npm run test locally, Karma will throw an error saying Some of your tests did a full page reload! and abort the test run. I think there's a bug in one of our tests that only occurs depending on the order in which they run (which is intentionally randomised). I can't see any tests that call window.location.reload(), so it must be triggered by some other means (maybe a click or form submission). This is a fun doozy.

Steps to reproduce

Run npm run test multiple times until the error occurs.

Expected result

The test run should always finish.

Actual result

The test run sometimes gets aborted early with the above error.

Environment

Firefox & Chrome, macOS

May be it is not a bedrock's bug. It can be a karma bug. btw This was an issue before version 6.0.0. See this.
@alexgibson are you still getting this error?

Good to know @Abhra303 thanks! We're on version 6 now, so let's keep an eye on this bug and we can close it if the problem seems to be gone :)

Going to close this and we can re-open if we still see it happening.
