This should address #57234.

Adding the teardown in case of isolation: none addresses this specific issue, and I see no potential negative effects in having it.

@cjihrig, was there a reason why we avoided it in the first place?

I'm using the test-runner in Electron, where usually isolation=none is the preferred way to use it (especially in the renderer process). It would be great to have this merged. Currently, we have to jump through hoops, like emitting a fake 'beforeExit' after the tests to get the runner to shut down in isolation.

This should address #57234.

Adding the teardown in case of isolation: none addresses this specific issue, and I see no potential negative effects in having it.

@cjihrig, was there a reason why we avoided it in the first place?

I'm using the test-runner in Electron, where usually isolation=none is the preferred way to use it (especially in the renderer process). It would be great to have this merged. Currently, we have to jump through hoops, like emitting a fake 'beforeExit' after the tests to get the runner to shut down in isolation.

I'm using the test-runner in Electron, where usually isolation=none is the preferred way to use it (especially in the renderer process). It would be great to have this merged. Currently, we have to jump through hoops, like emitting a fake 'beforeExit' after the tests to get the runner to shut down in isolation.

#62269 is also related.

Hey @inukshuk, I’ll take another look at the issue ASAP.

The PR got stuck due to some unexpected changes in behavior
