fstest

fstest provides a procedural macro attribute for simplifying integration tests involving temporary file system setups and optional Git repository initialization. This crate defines the #[fstest] macro, which wraps a test function and handles:

• Creation of a temporary working directory
• Optional initialization of a Git repository in the temporary directory
• Copying of specified input files into the temp directory
• Restoring the original working directory after test execution

Usage

use fstest::cmd_test;
#[cmd_test(repo = true, files = ["tests/data/input.txt", "tests/data/config.toml"])] //arguments are optional!
fn my_test(tempdir: &std::path::Path) {
    // test code working within `tempdir`
}

See examples folder for examples.
