Explain the process of testing and debugging Rust applications. What tools and techniques are commonly used?

Testing and debugging are critical processes in software development, including Rust applications. They help ensure the correctness, reliability, and stability of the codebase. Let's explore the process of testing and debugging Rust applications, along with commonly used tools and techniques: Testing Rust Applications: 1. Unit Testing: * Unit testing is performed to validate the individual units or components of the code, such as functions, modules, or structs, in isolation. * Rust's built-in testing framework, `std::test`, provides the `#[test]` attribute to mark functions as unit tests. Developers can use assertions, such as `assert_eq!` and `assert!`, to check expected behavior and outcomes. * The `cargo test` command is used to run all the unit tests in the project. It automatically discovers and executes the tests, providing clear output and summary. 2. Integration Testing: * Integration testing focuses on verifying the interactions between different components or modules of the application, ensuring their proper integration. * Rust supports integration testing through separate test directories. Integration tests are written in separate files within the `tests` ....
