Testing concepts to learn before Playwright
- Test case design: positive, negative, boundary values
- Test levels: unit, integration, end-to-end
- Bug reports: steps, expected vs actual, evidence
- Regression testing and smoke tests
- What to automate and what to keep manual

Django concepts to learn first
- Project vs app structure
- Models and migrations (python manage.py makemigrations / migrate)
- Views, URLs and templates
- Forms and validation
- Authentication and the admin site
- Django ORM queries

from playwright.sync_api import Page, expect

BASE = "http://localhost:8000"

def test_login_shows_dashboard(page: Page):
    page.goto(f"{BASE}/accounts/login/")
    page.get_by_label("Username").fill("demo_user")
    page.get_by_label("Password").fill("demo-pass-123")
    page.get_by_role("button", name="Log in").click()
    expect(page).to_have_url(f"{BASE}/dashboard/")
    expect(page.get_by_text("Welcome, demo_user")).to_be_visible()

def test_wrong_password_shows_error(page: Page):
    page.goto(f"{BASE}/accounts/login/")
    page.get_by_label("Username").fill("demo_user")
    page.get_by_label("Password").fill("wrong")
    page.get_by_role("button", name="Log in").click()
    expect(page.get_by_text("Please enter a correct username and password")).to_be_visible()

# tests.py — run with: python manage.py test
from django.contrib.auth.models import User
from django.test import TestCase
from django.urls import reverse

class DashboardTests(TestCase):
    def setUp(self):
        User.objects.create_user("demo_user", password="demo-pass-123")

    def test_dashboard_requires_login(self):
        resp = self.client.get(reverse("dashboard"))
        self.assertEqual(resp.status_code, 302)   # redirected to login

    def test_dashboard_after_login(self):
        self.client.login(username="demo_user", password="demo-pass-123")
        resp = self.client.get(reverse("dashboard"))
        self.assertContains(resp, "Welcome, demo_user")

Week 1: Testing fundamentals, Python basics
Week 2: Playwright setup, locators, actions, assertions
Week 3: Fixtures, test data, page object pattern
Week 4: Running in CI (GitHub Actions), traces and reports
Week 5: API testing with Playwright's request context
Week 6: Test suite for a real demo app, documented

Week 1: Python refresh, Django project setup
Week 2: Models, migrations, admin
Week 3: Views, URLs, templates, forms
Week 4: Authentication, permissions
Week 5: Django REST Framework basics
Week 6: Deploy a small app; add tests

Build + test project
☐ Django app with login and one form
☐ Django unit/integration tests
☐ Playwright tests for login and form journeys
☐ GitHub Actions runs both on every push
☐ README explains how to run app and tests
