rb-sys-test-helpers

Helpers for testing Ruby extensions from Rust

Usage

Add this to your Cargo.toml:

toml [dev-dependencies] rb-sys-env = { version = "0.1" } rb-sys-test-helpers = { version = "0.2" }

Then, in your crate's build.rs:

```rust,ignore pub fn main() -> Result<(), Box> { let _ = rbsysenv::activate()?;

Ok(())

} ```

Then, you can use the with_ruby_vm function in your tests:

```rust

[cfg(test)]

mod tests { use rbsystesthelpers::rubytest; use rbsys::{rbnum2fix, rbint2big, FIXNUMP};

#[ruby_test]
fn test_something() {
    // Your test code here will have a valid Ruby VM (hint: this works with
    // the `magnus` crate, too!)
    //
    // ...

    let int = unsafe { rb_num2fix(1) };
    let big = unsafe { rb_int2big(9999999) };

    assert!(FIXNUM_P(int));
    assert!(!FIXNUM_P(big));
}

} ```
