Crate testpath

Companion 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

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!");
}

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.

Structs

SubPath

A Path that lives within a TestPath and must not outlive it.

TempDirCleanup

Augment a TempDir with a custom callback function that can do additional cleanup work (like unmounting filesystem etc.)
