Just an update, I found out the problem was that the e2e test did not wait for the async methods of the PageObject.
Fixed it by making my unit test block async and waiting for the page.navigateTo() and page.getPageTitle() events.
it('should display welcome message', async () => {
await page.navigateTo();
expect(await page.getPageTitle()).toContain('Overview');
});
Maybe this can be updated in the Ionic starter templates, I believe the Angular starter contains the async/await pattern in their starters.

Hey there,
Apologies for the delay. The tabs applications do not have this test anymore, so I am going to close this.
