Why doesn't println! output text in Rust unit tests?

Hello! I started learning Rust and encountered a strange problem when writing unit tests. I want to output debug information using the `println!` macro, but nothing appears in the terminal. Here's my code: ```rust #[cfg(test)] mod tests { #[test] fn test_debug_output() { let value = 42; println!("Value: {}", value); assert_eq!(value, 42); } } ``` When I run the tests with `cargo test`, I only see: ``` running 1 test test tests::test_debug_output ... ok test result: ok. 1 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out ``` There's no output of `"Value: 42"`. I expected `println!` to work like in normal code. Why is this happening? How can I see debug output during testing? I'm using
