Rustgen is a random program that can generate correct runnable Rust programs along with the expected output of the program. It's primary purpose is to find compiler bugs either through comparing the output of running the test program with the expected output, or through differential testing.
Clone the project
git clone https://github.com/lukyxu/rust-genGo to the project directory
cd rust-genBuild and run RustGen Generate
cargo run --bin --release rust-gen-generateBuild and run RustGen Runner for 100 programs and saving all outputs including generated code and binaries.
cargo run --bin rust-gen-runner --release -- -n 100 -sTo run tests, run the following command
cargo testRust Gen creates programs with the following features:
