Similar to [trybuild], but allows you to test how declarative or procedural macros are expanded.

*Minimal Supported Rust Version: 1.56*

----

## Documentation

Please refer to the [documentation](https://docs.rs/macrotest).

## Example

Install [`cargo expand`].

Add to your crate's Cargo.toml:

```toml
[dev-dependencies]
macrotest = "1"
```

Under your crate's `tests/` directory, create `tests.rs` file containing the following code:

```rust
#[test]
pub fn pass() {
    macrotest::expand("tests/expand/*.rs");
}
```

Populate the `tests/expand/` directory with rust source files. Each source file is a macro expansion test case.

See [test-project](test-project) and [test-procmacro-project](test-procmacro-project) for the reference.
