[−][src]Crate goldenfile
This library provides a simple API for goldenfile testing.
Goldenfile tests generate one or more output files as they run. At the end of the test, the generated files are compared to checked-in "golden" files produced by previous runs. This ensures that all changes to goldenfiles are intentional, explicit, and version controlled.
Example
#[test] fn test() { let mut mint = Mint::new("tests/goldenfiles"); let mut file1 = mint.new_goldenfile("file1.txt").unwrap(); let mut file2 = mint.new_goldenfile("file2.txt").unwrap(); write!(file1, "Hello ").unwrap(); write!(file1, "World!").unwrap(); write!(file2, "Foo").unwrap(); write!(file2, "Bar").unwrap(); // When the Mint goes out of scope, it will check the new contents of file1 // and file2 against their version controlled "golden" contents and fail the // test if they differ. // // To update the goldenfiles themselves, run: // // env REGENERATE_GOLDENFILES=1 cargo test // }
