# [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):**
```typescript
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):**
```typescript
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

- Fix implementation: 1 hour
- Testing and validation: 1 hour
- Audit PR 2/3 files: 30 minutes

**Target Completion:** TBD (post-Phase 2)
