give exporters some time to disconnect

[michalskrivanek]

this is supposed to help with a flaky test "can lease and connect to exporters". The delete leases operation before this test causes exporters to disconnect, but it can take a short while to initiate that, and the kubectl wait in wait_for_exporter() can catch the Online/Registered state from before the disconnect. Let's see if it helps...

Summary by CodeRabbit

• Bug Fixes

  • Improved reliability of exporter availability checks by introducing a brief initial delay before validating Online/Registered states. No changes to workflows, configuration, or user-facing behavior.

• Tests

  • Adjusted test timing to better accommodate transient state changes, reducing intermittent failures and improving test stability. No functional changes or public API modifications; overall application behavior remains unchanged.

Walkthrough

A 2-second sleep was inserted at the start of the wait_for_exporter function in tests.bats, with comments explaining reconnection timing after a lease. Subsequent waits for Online and Registered states are unchanged. No public APIs or exported declarations were modified.

Changes

Cohort / File(s)	Summary
Test timing adjustment tests.bats	Inserted an initial 2s sleep in wait_for_exporter with explanatory comments to handle exporter disconnect/reconnect after lease; existing waits for Online/Registered remain unchanged.

Poem

I tap my paw and count to two,
A gentle pause—the tests renew.
Online, Registered, all in line,
A leased hop back, perfectly fine.
With patient ears and whiskers set,
This rabbit times the flakiest net. 🐇⏱️

Learning: In the jumpstarter E2E test suite (tests.bats), the background exporter processes started in the "can run exporters" test are intentionally kept running to support subsequent tests like "can operate on leases" and "can lease and connect to exporters". These processes should not be cleaned up within individual test cases.

9-11: kubectl isn’t available in this environment, so I can’t verify the --for=jsonpath support automatically. Please run the following on your local setup and confirm the presence of the flag:

kubectl version --client --short
kubectl wait --help | sed -n '1,120p'  # verify `--for=jsonpath` is listed

---

9-11: Confirm flake reduction before merging
The sleep 2 adds 2 s to every wait_for_exporter call; please install Bats and rerun the “can lease and connect to exporters” test multiple times (e.g., 10×) to compare failure rates before vs. after, or otherwise manually verify the mitigation’s effectiveness.
