ASP.NET Core Integration Testing Best Practises
Integration testing is a type of software testing essential for validating the interactions between different components of an application, ensuring they work together as expected. The main goal of integration testing is to identify any issues that may arise when these components interact with each other.
What are these components?
For example: databases, caches, message queues, APIs, external services, etc.
What is the difference between unit and integration testing?
Unit Testing: typically uses mocks or stubs to simulate dependencies, ensuring the test environment is controlled and isolated. Integration Testing: uses actual implementations of dependencies like databases, message queues, external services, and APIs to validate real interactions.
In this blog post, I will share my experience and tell you what are, in my opinion, the best practices for integration testing in ASP.NET Core applications. I will give you the tips I gained during more than 10 years of experience of creating production applications and writing integration tests for them. After reading this blog post, you will be able to write integration tests that are useful, are easy and fun to write, and a pleasure to maintain.
