What are some best practices for testing in Rust?

Some best practices for testing in Rust include using the built-in test framework, writing unit tests, and leveraging integration tests.

Can you explain how to write a unit test in Rust?

Sure! In Rust, you can write a unit test by creating a function annotated with #[test]. Here's a simple example:

#[cfg(test)]
mod tests {
    use super::*;

    #[test]
    fn test_add() {
        assert_eq!(add(2, 3), 5);
    }
}

What is the difference between unit tests and integration tests?

Unit tests focus on individual components, while integration tests check how different parts of your application work together.

How can I run my tests in Rust?

You can run your tests in Rust by using the command cargo test in your terminal. This will execute all tests in your project.
