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

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

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

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