Attribute Macro testing::fixture[][src]

#[fixture]
Expand description

Create tests from files.

NOTE: Path should be relative to the directory of Cargo.toml file. This is limitation of current proc macro api.

Why

If you create test dynamically, running a specific test become very cumbersome.

For example, if you use test crate with nightly, you can’t use cargo test foo to run tests with name containing foo. Instead, you have to implement your own ignoring logic

Usage

If you want to load all typescript files from pass

 
#[fixture("pass/**/*.{ts,tsx}")]
fn pass(file: PathBuf) {
    // test by reading file
}

Return value

The function is allowed to return Result on error. If it’s the case

Ignoreing a test

If the path to the file contains a component starts with . (dot), it will be ignore. This convention is widely used in many projects (including other languages), as a file or a directory starting with . means hidden file in unix system.

Note that they are added as a test #[ignore], so you can use cargo test -- --ignored or cargo test -- --include-ignored to run those tests.

Roadmap

  • Support async function
