| # Testing | |
| You can test the `web-sys` crate by running `cargo test` within the | |
| `crates/web-sys` directory in the `wasm-bindgen` repository: | |
| ```sh | |
| cd wasm-bindgen/crates/web-sys | |
| cargo test --target wasm32-unknown-unknown --all-features | |
| ``` | |
| The Wasm tests all run within a headless browser. See [the `wasm-bindgen-test` | |
| crate's | |
| `README.md`](https://github.com/rustwasm/wasm-bindgen/blob/master/crates/test/README.md) | |
| for details and configuring which headless browser is used. |
