`trycmd` is a test harness that will enumerate test case files and run them to verify the
results, taking inspiration from
[trybuild](https://crates.io/crates/trybuild) and [cram](https://bitheap.org/cram/).

## Example

To create a minimal setup, create a `tests/cli_tests.rs` with
```rust,no_run
#[test]
fn cli_tests() {
    trycmd::TestCases::new()
        .case("tests/cmd/*.toml")
        .case("README.md");
}
```
and write out your test cases in `.toml` files along with examples in your `README.md`.

Run this with `cargo test` like normal.  `TestCases` will enumerate all test case files and
run the contained commands, verifying they run as expected.

See the [docs](http://docs.rs/trycmd) for more.
