test(e2e): add simple stress test suite#1188
Merged
Conversation
This commit makes `migrationTargetNodes()` less conservative: * Instead of relying on RS status fields, rely exclusively on instance status, avoiding occasionaly inconsistency. * Return list of all replicant nodes if no cluster members belong to "update" replicant set, mirroring original intention.
This commit introduces test suite, aimed at stressing the controller with frequent EMQX CR spec changes. Currently, it supports: * scaling core set up and down, * scaling replicants up and down.
This commit simplifies E2E test suite setup by moving Prometheus related fixtures to its own related test group module.

Summary
This PR focuses on a new basic stress test suite. This suite applies a short sequence of mutations to the EMQX CR under test in a quick succession and verifies that Operator handles them smoothly. Currently, only mutations are scaling cores and replicants up and down.
Apart from that, this PR:
