Elixir: Testing External Services with Integration & E2E Strategies

Effectively testing Elixir applications that depend on external services is crucial for stability, but can be complex without the right strategies. This course provides a foundational understanding of various approaches to confidently test interactions with external HTTP services, ensuring your Elixir applications are robust and maintainable. ### What you'll learn * Understand foundational concepts of integration and end-to-end testing for external dependencies. * Learn to simulate external HTTP services using dedicated test servers and stubs. * Apply ExVCR to record and replay HTTP interactions for consistent and fast testing. * Implement effective mocking and stubbing techniques to isolate external service calls in Elixir. * Configure test environments for safe and efficient interaction with real external services. * Grasp dependency injection patterns to build more testable Elixir applications. The course begins with core testing concepts, then progresses through various strategies for interacting with and simulating external services, culminating in practical application of tools like ExVCR. This course is designed for beginner Elixir developers who want to build robust applications by mastering the art of testing external service integrations. No prior experience with advanced testing techniques is required. Enroll now to build confidence in your Elixir application's reliability.
