[Test Quality] Fix weak assertions in certificates.spec.ts

Created: February 3, 2026 Status: Open Priority: Low Labels: test-quality, technical-debt, low-priority Milestone: Post-Phase 2 cleanup

---

Description

Two tests in certificates.spec.ts have weak assertions that always pass, which were identified during Phase 2.1 Supervisor code review (PR #1 checkpoint feedback).

Affected Tests

1. "should display empty state when no certificates exist" (line 93-106)

• Current: expect(hasEmptyMessage || hasTable).toBeTruthy() (always passes)
• Issue: Assertion is a logical OR that will pass if either condition is true, making it impossible to fail
• Fix: Explicit assertions with database cleanup in beforeEach

2. "should show loading spinner while fetching data" (line 108-122)

• Current: expect(hasTable || hasEmpty).toBeTruthy() (always passes)
• Issue: Same logical OR pattern that cannot fail
• Fix: Test isolation and explicit state checks

---

Root Cause

Database State Dependency: Tests assume a clean database or pre-populated state that may not exist in CI or after other tests run.

Weak Assertion Pattern: Using || (OR) with .toBeTruthy() creates assertions that always pass as long as one condition is met, even if the actual test intent is not validated.

---

Action Items

• Add database cleanup in beforeEach hook

  • Clear certificates table before each test
  • Ensure known starting state

• Replace .toBeTruthy() with explicit state checks

  • Empty state test: expect(emptyMessage).toBeVisible() AND expect(table).not.toBeVisible()
  • Loading test: expect(spinner).toBeVisible() followed by expect(spinner).not.toBeVisible()

• Use test.skip() or mark as flaky until fixed

  • Document why tests are skipped
  • Track in this issue

• Audit PR 2/3 files for similar patterns

  • Search for .toBeTruthy() usage in:
    • proxy-hosts.spec.ts (PR #2)
    • access-lists-crud.spec.ts (PR #3)
    • authentication.spec.ts (PR #3)
  • Document any additional weak assertions found

---

Example Fix

Before (Weak):

test('should display empty state when no certificates exist', async ({ page }) => {
  await test.step('Check for empty state or existing certificates', async () => {
    const emptyMessage = page.getByText(/no certificates/i);
    const table = page.getByRole('table');

    const hasEmptyMessage = await emptyMessage.isVisible().catch(() => false);
    const hasTable = await table.isVisible().catch(() => false);

    expect(hasEmptyMessage || hasTable).toBeTruthy();  // ❌ Always passes
  });
});

After (Strong):

test.describe('Empty State Tests', () => {
  test.beforeEach(async ({ request }) => {
    // Clear certificates from database
    await request.delete('/api/v1/certificates/all');
  });

  test('should display empty state when no certificates exist', async ({ page }) => {
    await page.goto('/certificates');
    await waitForLoadingComplete(page);

    const emptyMessage = page.getByText(/no certificates/i);
    const table = page.getByRole('table');

    // ✅ Explicit assertions
    await expect(emptyMessage).toBeVisible();
    await expect(table).not.toBeVisible();
  });
});

E2E Test Failures (Phase 2.4 Validation)

These tests failed during full browser suite execution:

Chromium:

• ❌ certificates.spec.ts:93 - empty state test
• ❌ certificates.spec.ts:108 - loading spinner test

Firefox:

• ❌ certificates.spec.ts:93 - empty state test
• ❌ certificates.spec.ts:108 - loading spinner test

Error Message:

Error: expect(received).toBeTruthy()
Received: false

---

Acceptance Criteria

• Both tests pass consistently in all 3 browsers (Chromium, Firefox, WebKit)
• Tests fail when expected conditions are not met (e.g., database has certificates)
• Database cleanup is documented and runs before each test
• Similar weak assertion patterns audited in PR 2/3 files
• Tests are no longer marked as skipped/flaky

---

Priority Rationale

Low Priority: These tests are not blocking Phase 2 completion or causing CI failures. They are documentation/technical debt issues that should be addressed in post-Phase 2 cleanup.

Impact:

• Tests currently pass but do not validate actual behavior
• False sense of security (tests can't fail even when functionality is broken)
• Future maintenance challenges if assumptions change
