I want to use parametrized testing and found rstest that can do this well.

adding: use rstest::rstest; in the main.rs file and putting the #[rstest] also inside main.rs runs fine on cargo test

but if I want to build the programm with cargo build I got this error

| use rstest::rstest;
 |     ^^^^^^ use of undeclared crate or module `rstest`

so the question is: How do I have to organize my code to use #[rstest] and also be able to build/run the program ?

CodePudding user response:

Depending if you want to run the code using rstest with the non-test build or not you either have to add rstest in your Cargo.toml

[dependencies]
rstest = "*"

or you have to remove the code using rstest from non test builds:

#[cfg(test)]
use rstest::rstest;
