Summary by CodeRabbit

  • Bug Fixes
    • Added validation for the E2E run-as setting so invalid values stop the test run early.
    • Improved startup logging to clearly show whether tests are running in admin or non-admin mode.

The --run-as flag accepts any string, but only "admin" has special behavior. Typos like --run-as=admon or --run-as=adming do nothing and fall back to non-admin mode and the test is run as non-admin. Users get unexpected behavior without any error message

Example of the problem:
$ User makes a typo
$ ginkgo run -v --focus="\[MTA-850\]" e2e-tests/tests/tier1 -- --k8sdeploy-bin=~/k8s-apps-deployer/venv/bin/k8sdeploy --crane-bin=~/migtools-crane/crane/crane --source-context=kind-source-cluster --target-context=kind-dest-cluster --source-nonadmin-context=crane-source-context --target-nonadmin-context=crane-dest-context --run-as=admon

Solution:
Fail fast with a clear error message:
Invalid --run-as value: "admon". Valid values: "admin" or empty string (for non-admin mode)

Summary by CodeRabbit

  • Bug Fixes
    • Added startup validation for the test run mode so invalid run-as values are caught early.
    • Improved test run logging to clearly show whether suites are running in admin or non-admin mode.

In `@e2e-tests/config/config.go`:
- Around line 19-30: The ValidateAndLogRunAsFlag function is exiting the process
directly on invalid input, which prevents Ginkgo from reporting the failure
normally. Change this helper to return an error instead of calling log.Fatalf,
and update the BeforeSuite callers in the tier0 and tier1 suites to assert
success (for example via Fail/Expect) so invalid --run-as values are surfaced as
reportable suite failures while still keeping the existing log messages for the
valid admin and non-admin paths.
- Around line 19-30: Add a focused unit test for ValidateAndLogRunAsFlag in
e2e-tests/config that exercises the empty RunAs, "admin", and invalid value
branches without relying on full e2e suites. Use the existing RunAs global and
validate that the function logs the expected mode for empty and admin values,
and that an invalid value triggers the fatal path (for example by running it in
a subprocess or equivalent test-safe fatal handling).
