#QuickCheck for Rust

Build Status

Use quick_check to check that a specified property holds for values of trait Arbitrary + Shrink.

Now this library adheres to rustpkg's package structure. Thus you can conveniently add this line to your program,

extern mod qc = "github.com/lilac/quick-check";

without needing to install this library manually.

##Example Suppose the current Rust workspace is ~/workspace/rust/, create a dir for the demo program

$mkdir -p src/qc-demo

and then write the sample code as follows: $cat src/qc-demo/main.rs

extern mod qc = "github.com/lilac/quick-check";

fn is_sorted<T: TotalOrd>(v: &[T]) -> bool {
    v.windows(2).all(|w| { w[0].cmp(&w[1]).le(&Greater) })
}

fn main() {
    qc::quick_check("sort", qc::config.verbose(true).trials(500),
        |mut v: ~[u8]| { v.sort(); is_sorted(v) });
}

Now we build this new pkg with a command:

$rustpkg build qc-demo

then install the built pkg with:

$rustpkg install qc-demo

finally the compiled binary qc-demo is in the bin subdir of the current workspace.

Issues

  • Clean up Lazy and Shrink, implement Arbitrary and Shrink further
