macrotest
Similar to trybuild, but allows you to test how declarative or procedural macros are expanded.
Minimal Supported Rust Version: 1.34.0
Documentation
Please refer to the documentation.
Example
Install nightly rust and cargo expand
.
Add to your crate's Cargo.toml:
[dev-dependencies]
macrotest = "1"
Under your crate's tests/
directory, create tests.rs
file containing the following code:
#[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 and test-procmacro-project for the reference.
