trycmd

Snapshot testing for a herd of CLI tests

trycmd aims to simplify the process for running a large collection of end-to-end CLI test cases, taking inspiration from trybuild.

Example

Here's a trivial example:

#[test]
fn cli_tests() {
    trycmd::TestCases::new()
        .case("tests/cmd/*.trycmd");
}

See the docs for more.
