Environment variable

Run test case when the environment variable is set. A solution for this issue of rust-lang.

#[cfg(test)]
mod tests {

    // PWD environment variable exists
    #[test_with::env(PWD)]
    fn test_works() {
        assert!(true);
    }

    // NOTHING environment variable does not exist
    #[test_with::env(NOTHING)]
    fn test_ignored() {
        panic!("should be ignored")
    }
}

Result of cargo test

running 2 tests
test tests::test_ignored ... ignored
test tests::test_works ... ok

test result: ok. 1 passed; 0 failed; 1 ignored; 0 measured; 0 filtered out; finished in 0.00s

If the test depends on more than one environment variables, you can write it with multiple variables, #[test_with::env(VAR1, VAR2)].

File/Folder

Run test case when the file or folder exist. This is good for testing with database config. If you want to check the folder exist or not, please use path.

#[cfg(test)]
mod tests {

    // hostname exists
    #[test_with::file(/etc/hostname)]
    fn test_works() {
        assert!(true);
    }

    // nothing file does not exist
    #[test_with::file(/etc/nothing)]
    fn test_ignored() {
        panic!("should be ignored")
    }

    // etc exists
    #[test_with::path(/etc)]
    fn test_works_for_path() {
        assert!(true);
    }
}

If the test depends on more than one file or path, you can write it with multiple file/path, #[test_with::file(/file1, /file2)] or #[test_with::path(/folder, /file)].
