| # Running `wasm-bindgen`'s Tests |
| |
| ## Wasm Tests on Node and Headless Browsers |
| |
| These are the largest test suites, and most common to run in day to day |
| `wasm-bindgen` development. These tests are compiled to Wasm and then run in |
| Node.js or a headless browser via the WebDriver protocol. |
| |
| ```bash |
| WASM_BINDGEN_SPLIT_LINKED_MODULES=1 cargo test --target wasm32-unknown-unknown |
| ``` |
| |
| 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. |
| |
| ## Sanity Tests for `wasm-bindgen` on the Native Host Target |
| |
| This small test suite just verifies that exported `wasm-bindgen` methods can |
| still be used on the native host's target. |
| |
| ``` |
| cargo test |
| ``` |
| |
| ## The Web IDL Frontend's Tests |
| |
| ``` |
| cargo test -p webidl-tests --target wasm32-unknown-unknown |
| ``` |
| |
| ## The Macro UI Tests |
| |
| These tests assert that we have reasonable error messages that point to the |
| right source spans when the `#[wasm_bindgen]` proc-macro is misused. |
| |
| You can run these tests by running `cargo test` for the `wasm-bindgen-macro` |
| crate: |
| |
| ``` |
| cargo test -p wasm-bindgen-macro |
| ``` |
