Angular: Pruebas unitarias con Jasmine y Karma

Learn Angular Unit Testing with Jasmine and Karma! This comprehensive course guides you from basic to advanced unit testing techniques, empowering you to write high-quality tests that truly validate your code's functionality, not just lines. Discover when and how to apply different testing strategies for optimal results.

Here's what you'll master:

• Introduction to Unit Testing: Get started with an overview of unit testing, its importance, and the tools you'll use. We'll cover the necessary software setup and a course overview.
• Understanding Core Concepts: Dive into the fundamentals of unit tests, integration tests, and end-to-end (E2E) tests. Learn how unit tests work, when to implement them, and understand code coverage. Explore Jasmine and Karma – the essential testing frameworks.
• Jasmine & Karma Deep Dive: Configure Karma for your project, including setting up the coverage folder. Learn to run tests, add new dependencies (especially for Angular 11+), and effectively manage your test environment.
• Writing Effective Unit Tests: Apply unit testing to real-world Angular components. We'll walk through a practical example, including:
  • Installing and using JSON Server for test data.
  • Structuring test files (.spec).
  • Configuring TestBed.
  • Creating your first test cases.
  • Handling common test failures.
  • Testing methods with and without return values (using spyOn).
  • Testing private methods.
  • Testing component lifecycle hooks (e.g., ngOnInit).
  • Testing subscriptions and Observables.
  • Mocking services.
  • Using xit, fit, xdescribe, fdescribe, beforeEach, beforeAll, afterEach, and afterAll for test organization.
  • Debugging tests in Karma.
  • Testing pipes.
  • Testing services with API calls.
  • Exploring different ways to instantiate components and services for testing.
  • Testing routes with RouterTestingModule.
• Angular Material Testing: Learn to test Angular Material components, specifically using MatDialog in the context of a cart component. Test confirmation dialogs and ensure proper functionality.
• Advanced Testing Techniques: Expand your knowledge with:
  • Introduction to integration testing.
  • Automating tests before build generation.
  • Testing forms.
  • Testing document and window extensions.
• Bonus Resources & Wrap-up: Get final tips, a closing message, and extra information.

Important Note: This course is similar to "Angular: Unit Testing with Jest," but utilizes Jasmine syntax instead of Jest. You'll be applying the same unit testing principles to your Angular projects.
