♻️ [RUM-5101] Use registerCleanupTask instead of afterEach for test cleanup

[amortemousque]

Motivation

Previously, we had to manually clean up every test mock in the afterEach block of every test. (ex)

Now, with registerCleanupTask, the cleanup task is automatically registered directly from the test mock itself, simplifying the process (ex)

Let’s generalize its usage!

Changes

Uses registerCleanupTask for

• mockZoneJs
• mockXhr
• mockFetch
• mockVisibilityState
• mockSyntheticsWorkerValues
• mockReportingObserver
• mockLocation
• mockClock

Testing

• [ ] Local
• [ ] Staging
• [x] Unit
• [ ] End to end

I have gone over the contributing documentation.
