# Testing | |
You can test the `js-sys` crate by running `cargo test --target | |
wasm32-unknown-unknown` within the `crates/js-sys` directory in the | |
`wasm-bindgen` repository: | |
```sh | |
cd wasm-bindgen/crates/js-sys | |
cargo test --target wasm32-unknown-unknown | |
``` | |
These tests are largely executed in Node.js right now via the | |
[`wasm-bindgen-test` framework](../../wasm-bindgen-test/index.html) |
