Companinon crate to ‘bintest' and 'testcall’, implements facilities for running tests in directories.

Description

Allows creating of (temporary) test directories, optionally with a custom callback for cleanup. Populating these with content for testing and provide assertion to validate the content.

Example

#[test]
fn test_something() {
    let tmpdir = TempDir::new().expect("TempDir created");
    tmpdir.create_file("path/to/testfile", "Hello File!".as_bytes());
    tmpdir
        .sub_path("path/to/testfile")
        .assert_utf8("Hello File!");
}

Future Plans

New features will be added as needed, PR’s are welcome. This is work in progress.

Panics vs. Results

'testpath' is made explicitly for writing tests. To ease this it prefers aborting by panic over error handling. When anything goes wrong the test is aborted and the cause is reported.
