End-to-End Testing Your Rust Service

<p>If you&rsquo;re building a web API in Rust, you need a way to test your endpoints end to end. Unit tests ensure your logic is correct, but a proper end-to-end test can verify that your infrastructure, routing, database migrations, and security settings are correct. Since most modern services manage these pieces with code, testing them just like your application code is a good idea. One of the best ways is with an end-to-end test in your CI/CD process. For Rust services,&nbsp;<code>cargo</code>&nbsp;makes this painless.</p> <h1>The Point of an End-to-End Test</h1> <p>With an end-to-end test, your goal is to experience your service from a client&#39;s perspective. You want to verify that the client isn&rsquo;t going to have any problems with your latest deploy (other than versioned, planned breaking changes). You&rsquo;re not just verifying that your logic is correct (which you can verify with unit tests) but that your software, hardware, networking, and permissions all work together.</p> <p>Unit tests and localized use case testing can verify your business logic, but the end-to-end test also checks the infrastructure your software is running on and interacting with. A robust end-to-end test suite with good coverage also helps you detect regressions in your infrastructure, allowing you to confidently make infrastructure changes.</p> <p><a href="https://betterprogramming.pub/end-to-end-testing-your-rust-service-d68b50985c9e">Click Here</a></p>
