Walkthrough

Adds two Cypress test files: a smoke test for impersonation modal and banner behavior, and a comprehensive E2E suite exercising multi-group impersonation and RBAC across namespaces with setup/teardown and helper utilities. (47 words)

Changes

Cohort / File(s)	Summary
Smoke test frontend/packages/integration-tests-cypress/tests/app/impersonate-user-smoke.cy.ts	New Cypress smoke tests for impersonation modal: username input, start/stop impersonation flows, validation states, group UI behavior (mocked/real), and banner persistence across SPA navigation; includes cleanup to stop impersonation.
Comprehensive E2E impersonation suite frontend/packages/integration-tests-cypress/tests/app/impersonate-user.cy.ts	New extensive Cypress suite that creates namespaces/groups/GroupBindings and test pods, provides startImpersonation/stopImpersonation helpers, and covers single- and multi-group RBAC scenarios, group search/filter, selection mechanics, permission checks via oc commands, edge cases, and full setup/teardown.

Estimated code review effort

🎯 4 (Complex) | ⏱️ ~60 minutes

• Pay special attention to:
  • Setup/teardown: namespace, group, GroupBinding, and pod lifecycle and cleanup.
  • Helper functions startImpersonation / stopImpersonation and their UI selectors/state handling.
  • Use of oc commands and handling of non-zero exits or environment assumptions.
  • Mocking vs. real-group flows and tests that assert UI tooltip vs. banner rendering.
