Testing Ruby 2 Applications with RSpec

Learn RSpec for robust Ruby testing! This course provides a practical, hands-on approach to writing effective tests for your applications. We'll build a simple command line card game as we explore the core concepts of RSpec and best practices for test-driven development (TDD).

Here's what you'll master:

• RSpec Core: Understand the fundamental syntax and the command line runner to execute your tests.
• Expectation Library: Express complex assertions about your code with the powerful expectations library, allowing you to write clear and readable tests.
• Mocks: Utilize mocks to isolate units of code, simulate dependencies, and gain valuable design feedback. Learn how to specify interactions between objects for effective testing.
• RSpec Ecosystem: Explore the broader Ruby testing landscape, covering major RSpec versions and common patterns used in real-world projects.
• Testing Best Practices: Discover different types of tests (unit, integration, etc.), learn what to test, and when to apply various testing styles. We'll cover crucial aspects of writing maintainable and effective tests.

Through numerous worked examples, you'll gain practical experience applying these techniques. This course equips you with the skills to write high-quality, reliable Ruby tests using RSpec, leading to more robust and maintainable code. Perfect for developers looking to improve their testing skills and adopt a test-driven approach.
