How do I test async functions in Rust?
You can use the tokio
or async-std
testing frameworks to test async functions in Rust. Would you like an example?
Yes, please provide an example of testing an async function.
Sure! Here's a simple example using tokio
:
#[tokio::test]
async fn test_async_function() {
let result = async_function().await;
assert_eq!(result, expected_value);
}
This allows you to write tests that await async functions.
What if I want to test multiple async functions?
You can create multiple tests using the same #[tokio::test]
attribute for each async function. Just ensure each test is independent.
