Setting Up Elixir API Integration Tests for User-Like Interaction

Testing APIs from the perspective of an actual user is the most reliable way to ensure your application works in production. In Elixir, managing concurrent database state while simulating these real-world interactions can be challenging without the right patterns. This course teaches you how to write clean, maintainable integration tests that behave exactly like your end users, ensuring your API remains stable and correct. You will start by mastering foundational testing concepts, understanding the Elixir test environment, and exploring how to structure your test suite for maximum reliability. You will learn to manage database persistence safely across concurrent test runs, simulate HTTP requests, and handle authentication flows just like a real client application would. What you'll learn: - Understand the core principles of user-centric integration testing in Elixir - Configure test environments and manage database state safely across parallel tests - Simulate realistic user flows and multi-step API interactions - Handle authentication and authorization states within your test suite - Apply modern Elixir testing patterns using ExUnit and database sandboxes - Debug failing integration tests by reading and analyzing test logs This course guides you step-by-step from foundational testing concepts to advanced concurrency management, ensuring you can confidently verify your API's behavior. It is designed for beginner-to-intermediate Elixir developers who want to write reliable integration tests; no prior testing experience is required.
