## Resource

In this lesson, you’ll learn about: transitioning from unit tests to full integration testing in Ruby on Rails, simulating real user workflows and validating complete application behavior1. What Is Integration Testing?Using Ruby on Rails:🔹 Definition: Tests how multiple components work together 🔹 Difference from unit tests: Unit → test isolated parts Integration → test full workflows 👉 Key Insight Integration tests validate real-world application behavior, not just individual pieces2. Building a Complete User Flow🔹 Example flow: User registers User logs in User views profiles User edits their profile 👉 Key Insight Integration tests simulate actual user journeys from start to finish3. Essential Integration Toolsfollow_redirect!🔹 Purpose: Continue test after redirects 🔹 Example:post login_path, params: { email: "test@test.com", password: "123456" } follow_redirect! 👉 Key Insight Allows tests to move across multiple pages seamlesslyassert_select🔹 Purpose: Validate HTML content 🔹 Example:assert_select "h1", "Welcome" 👉 Key Insight Confirms that the correct UI elements are rendered4. Merging Unit Tests into Integration Tests🔹 Approach: Combine smaller tests into one full scenario 🔹 Example: Instead of testing login separately → include it in full flow 👉 Key Insight Integration tests provide higher confidence by covering entire processes5. Testing HTTP Requests (PATCH)🔹 Use case: Updating user data 🔹 Example:patch user_path(user), params: { user: { name: "Updated" } } 👉 Key Insight PATCH requests verify that updates are correctly processed and saved6. Debugging Through Integration Tests🔹 Common discoveries: Missing data causing crashes Frontend rendering issues Broken flows between pages 👉 Key Insight Integration tests reveal bugs that unit tests often miss7.
