Testing

You can test the web-sys crate by running cargo test within the crates/web-sys directory in the wasm-bindgen repository:

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 for details and configuring which headless browser is used.
