Attribute Macro fstest

#[fstest]

Attribute macro to create file-system-isolated integration tests with optional git repo setup.

This macro generates a #[test] function that:

• Creates a temporary directory
• Optionally initializes a Git repository (via repo = true)
• Optionally copies specified files into the temp directory (via files = "path1", "path2", ...)
• Invokes the annotated function (renamed with _inner suffix) with the temp directory path
• Resets the working directory after the test

Parameters

• repo: bool — If true, initializes a Git repository in the temp directory before the test.
• files: &[&str] relative file paths to copy.

Example

use fstest::fstest;

#[fstest(repo = true, files = ["tests/data/config.toml", "tests/data/input.txt"])]
fn integration_example() {
    let config_path = std::fs::Path::new("config.toml");
    assert!(config_path.exists());
}
