Explore automated testing in Rust through this 23-minute video tutorial. Learn the fundamental tools for writing effective tests, including test function anatomy, assertion macros, custom failure messages, and panic checks. Discover how to use Result in tests, run tests in parallel or consecutively, and manage test output. Gain insights into organizing tests, creating submodules for integration testing, and implementing tests for binary crates. Practice writing robust automated tests to ensure your Rust programs function as intended beyond basic compiler checks.
