# E2E Test Guidelines

## Philosophy

- Journey-style tests covering critical flows end-to-end
- **Strongly prefer adding `test.step()` to existing tests** over creating new tests - keeps suite fast and avoids duplicating slow setup flows
- Fix flaky tests immediately, regardless of when introduced

## Commands

```bash
pnpm playwright test --reporter=line --max-failures=1 2>&1
pnpm playwright test --workers=4 --repeat-each=5 --reporter=line 2>&1  # flaky detection
```

**NEVER use `--debug` or `--ui`** - opens GUI, blocks forever. This is a common mistake.

## Selectors (priority order)

1. `getByRole()` 
2. `getByTestId()`
3. `getByLabel()`
4. `getByText(/regex/i)`

## Critical Rules

- **Assert behaviour, not text** - text changes with copy edits/i18n
- **Independent tests** - use `beforeEach`, don't depend on prior test state
- **No arbitrary waits** - use `toBeEnabled()`, not `waitForTimeout()`

## Helpers

Import from `tests/e2e/helpers/`:
- `createNewIdentity(page)` - full new user flow
- `goToTransactions(page)`, `goToTags(page)`, etc.

Create helpers for multi-step reused flows. Don't wrap single Playwright calls.

## Pattern

```typescript
test.describe("Feature", () => {
  test.beforeEach(async ({ page }) => {
    await createNewIdentity(page);
    await goToFeature(page);
  });

  test("should do thing", async ({ page }) => {
    // Arrange → Act → Assert
  });
});
```
