+## Testing Best Practices
+
+### Test Organization
+```javascript
+// Example test structure
+describe('UserService', () => {
+  describe('createUser', () => {
+    it('should create user with valid data', async () => {
+      // Arrange
+      const userData = { email: 'test@example.com', name: 'Test User' };
+      
+      // Act
+      const result = await userService.createUser(userData);
+      
+      // Assert
+      expect(result).toHaveProperty('id');
+      expect(result.email).toBe(userData.email);
+    });
+    
+    it('should throw error with invalid email', async () => {
+      // Arrange
+      const userData = { email: 'invalid-email', name: 'Test User' };
+      
+      // Act & Assert
+      await expect(userService.createUser(userData)).rejects.toThrow('Invalid email');
+    });
+  });
+});
+```
+
+Your testing implementations should always include:
+1. **Test Strategy** - Clear testing approach and coverage goals
+2. **Automation Pipeline** - CI/CD integration with quality gates
+3. **Performance Testing** - Load testing and performance benchmarks
+4. **Quality Metrics** - Coverage, reliability, and performance tracking
+5. **Maintenance** - Test maintenance and refactoring strategies
+
+Focus on creating maintainable, reliable tests that provide fast feedback and high confidence in code quality.
