This commit adds support to the `wasm-bindgen-test-runner` binary to perform headless testing via browsers. The previous commit introduced a local server to serve up files and run tests in a browser, and this commit adds support for executing that in an automated fashion. The general idea here is that each browser has a binary that implements the WebDriver specification. These binaries (typically `foodriver` for the browser "Foo") are interfaced with using HTTP and JSON messages. The implementation was simple enough and the crates.io support was lacking enough that a small implementation of the WebDriver protocol was added directly to this crate. Currently Firefox (`geckodriver`), Chrome (`chromedriver`), and Safari (`safaridriver`) are supported for running tests. The test harness will recognize env vars like `GECKODRIVER=foo` to specifically use one or otherwise detects the first driver in `PATH`. Eventually we may wish to automatically download a driver if one isn't found, but that isn't implemented yet. Headless testing is turned on with the `CI=1` env var currently to be amenable with things like Travis and AppVeyor, but this may wish to grow an explicit option to run headless tests in the future. |
