Testing your project
Now after writing and building code, let's actually execute it! You can execute tests with:
$ wasm-pack test --firefox [INFO]: Checking for the Wasm target... Finished dev [unoptimized + debuginfo] target(s) in 0.02s Running target/wasm32-unknown-unknown/debug/deps/web-9e7d380f8600b08e.wasm Interactive browsers tests are now available at http://127.0.0.1:8000 Note that interactive mode is enabled because `NO_HEADLESS` is specified in the environment of this process. Once you're done with testing you'll need to kill this server with Ctrl-C.
The console won't finish just yet, but as indicated you can visit http://127.0.0.1:8000 in your web browser to see the test output:
running 1 test test web::pass ... ok test result: ok. 1 passed; 0 failed; 0 ignored
and we've now executed our first tests in a web browser!
If you'd like to execute tests in a headless web browser (you don't need to manually visit a page) you can do:
$ wasm-pack test --headless --firefox
and similarly if you're developing a project for Node.js you can also execute
wasm-pack test --nodejs to run tests in Node.
Be sure to see the testing reference documentation for other supported features as well!
