A "wrapper binary" used to execute wasm files as tests
This binary is intended to be used as a "test runner" for wasm binaries,
being compatible with
cargo test for the wasm target. It will
wasm-bindgen (or the equivalent thereof) and then
execute either Node.js over the tests or start a server which a browser can
be used to run against to execute tests. In a browser mode if
CI is in the
environment then it'll also attempt headless testing, spawning the server in
the background and then using the WebDriver protocol to execute tests.
For more documentation about this see the
wasm-bindgen-test crate README
and source code.
