Additional context The first issue that comes up is Error: Invalid Chai property: browserWindow. This can be temporarily fixed by removing the problem code @ line 33 of test.spec.js. The second issue is that the test always pass regardless if it should and it throws an assertion error. For example if I change the code at line 30 to return this.app.client .getWindowCount() .should.eventually.have.at.least(45) the test still passes but it returns this error: UnhandledPromiseRejectionWarning: AssertionError: expected 1 to be at least 45

Also, instead of using your own mocha config, try the official cli plugin, it may make things easier.

To fix, just use "spectron": "11.0.0", in your package.json.
