Iota Uz Iota Sdk E2e Testing

Prerequisites

1. E2E Database

The E2E tests use a separate iota_erp_e2e database. Create it if missing:

# Check DB connection params from .env (DB_HOST, DB_PORT, DB_PASSWORD)
grep '^DB_' .env

# Create the database (adjust host/port from .env)
PGPASSWORD=postgres psql -U postgres -h localhost -p 5438 -c "CREATE DATABASE iota_erp_e2e;"

# Run migrations
just e2e migrate up

2. Start the E2E Server

The server must run with test endpoints enabled:

PORT=3201 ORIGIN='http://localhost:3201' DB_NAME=iota_erp_e2e ENABLE_TEST_ENDPOINTS=true \
  go run -tags e2e ./cmd/server/main.go

Or use just e2e dev (uses air hot-reload, same env vars).

Verify it's running:

curl -s -o /dev/null -w "%{http_code}" http://localhost:3201/login
# Should return 200

3. Stop the Server When Done

kill $(lsof -ti:3201) 2>/dev/null

Running Tests

# Run a specific test file
cd e2e && npx playwright test tests/roles/roles.spec.ts --reporter=line

# Run a specific test by line number
cd e2e && npx playwright test tests/roles/roles.spec.ts:26 --reporter=line

# Run all E2E tests (headless)
just e2e ci

# Run with Playwright UI (interactive debugging)
just e2e run

Debug Loop

When fixing a failing E2E test, follow this loop:

1. Reproduce locally first — never iterate via CI pushes
2. Run the specific failing test by line number for fast feedback
3. Check screenshots in e2e/test-results/ after failures
4. Check video recordings (.webm) for timing/animation issues
5. Read the error context file in test-results for DOM snapshots
6. Fix and re-run until the specific test passes
7. Run the full test file to catch regressions in serial tests
8. Then push to CI

# Quick iteration: run just the failing test
cd e2e && npx playwright test tests/module/test.spec.ts:LINE --reporter=line

# After fixing, run the full suite
cd e2e && npx playwright test tests/module/test.spec.ts --reporter=line

# View failure screenshot
# (path shown in test output, use Read tool to view)

Common Patterns

Dialog Confirmation Buttons

The <dialog> top-layer positioning confuses Playwright's elementFromPoint() hit testing in headless Chromium. The bottom action bar (sticky footer) intercepts pointer events even though the dialog is visually on top.

Workaround: After verifying the dialog is visible, trigger the htmx form submit directly instead of clicking the confirm button:

// Open the confirmation dialog
await page.locator('[data-test-id="delete-btn"]').click();

// Wait for dialog to appear
const dialog = page.locator('[data-test-id="delete-confirmation-dialog"]');
await expect(dialog).toBeVisible();

// Trigger htmx delete directly (bypasses dialog hit-test issue)
await page.evaluate(() => {
  const form = document.getElementById('delete-form') as HTMLFormElement;
  (window as any).htmx.trigger(form, 'submit');
});

await page.waitForURL(/\/expected-path$/);

Selectors

Prefer data-test-id attributes over text-based or structural selectors:

// Good
page.locator('[data-test-id="save-role-btn"]')
page.locator('[data-test-id="dialog-confirm-btn"]')

// Fragile
page.locator('button').filter({ hasText: /Save/i })
page.getByRole('button', { name: /confirm/i })

Waiting for Alpine.js

import { waitForAlpine } from '../../fixtures/auth';
await waitForAlpine(page);

Database Reset and Seeding

Tests use beforeAll to reset and seed:

import { resetTestDatabase, seedScenario } from '../../fixtures/test-data';

test.beforeAll(async ({ request }) => {
  await resetTestDatabase(request, { reseedMinimal: false });
  await seedScenario(request, 'comprehensive');
});

Test Structure

Key Config

• Viewport: 1280x720 (Desktop Chrome)
• Test timeout: 60s
• Retries in CI: 2 (none locally by default)
• Workers: 1 (serial execution for data-dependent tests)
• Base URL: http://localhost:3201
