Testing apps

<TODO>

信息

We're working on making it easy to test components, but this is currently a work in progress.

Support for shallow rendering and a proposal to expose the code Yew uses internally for testing components can be found in the GitHub repository.

wasm_bindgen_test

The Rust Wasm working group maintains a crate called wasm_bindgen_test which allows you to run tests in a browser in similar fashion to how the built-in #[test] procedural macro works. More information is given in the Rust Wasm working group's documentation for this module.
