Simple golden file testing for Rust.

goldie::assert!(text);

🚀 Getting started

Add goldie to your project as a dev dependency.

cargo add goldie --dev

In your test function assert the contents using goldie::assert!. The golden filename will be automatically determined based on the test file and test function name. Run tests with GOLDIE_UPDATE=true to automatically update golden files.

#[test]
fn example() {
    let text = { /* ... run the test ... */ };

    // assert that the contents of ./testdata/example.golden
    // are equal to `text`
    goldie::assert!(text)
}

Templated golden files are also supported using goldie::assert_template!. Something implementing serde::Serialize needs to be provided as context in order to render the template. Values are rendered using upon e.g. {{ value.field }}. You cannot use GOLDIE_UPDATE=true to automatically update templated golden files.

#[test]
fn example() {
    let text = { /* ... run the test ... */ };

    // assert that the contents of ./testdata/example.golden
    // are equal to `text` after rendering with `ctx`.
    let ctx = upon::value!{ value: "Hello World!" };
    goldie::assert_template!(&ctx, text)
}
