Some of the E2E tests could be considered read-only, such as looping until a PromQL expression is true.

Additionally, some tests are non-disruptive: all their operations are performed within a temporary namespace without impacting the monitoring components' statuses.

We can t.Parallel() them to save some minutes.

Also, we can:

Isolate specific tests to enable parallel execution

Enhance the resilience of some tests and fix those prone to errors.

Fix some tests that were running wrong checks.

Make some the tests idempotent to be easily debugged and run locally
