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.
* Create bindings for RegExp
* Address review comments
- Split the constructor into two: `new` and `new_regexp`. This way we
can write RegExp::new("foo", "g") rather than
RegExp::new(&JsValue::from("foo"), "g").
- The js_name for the setter for lastIndex should be `lastIndex` and
not `set_lastIndex`. But fixing this causes a panic. Remove the
method for now.
The JS iterator protocol uses duck typing and we don't need separate
ArrayIterator and SetIterator etc types, we can have a single iterator type for
the whole protocol.
* Add a test harness to directly execute wasm tests
This commits adds a few new crates and infrastructure to enable comands like:
cargo test --target wasm32-unknown-unknown
The intention here is to make it as low-friction as possible to write wasm tests
and also have them execute in a reasonable amount of time. Eventually this is
also hopefully enough support to do things like headless testing!
For now though this is defintely MVP status rather than fully fleshed out.
There's some more information at `crates/test/README.md` about how it works and
how to use it, but for now this is mainly intended to play around with locally
in this repository for our own tests.
* Port a numbe of `js-sys` tests to the new test framework
This commit ports a number of existing tests for the `js-sys` crate over to the
new test framework created in the previous commit, showing off how they can be
executed as well as drastictlly simplifying the tests themselves! This is
intended to be a proof of concept for now which we can refine over time. This
should also show off that it's possible to incrementally move over to the new
test framework.
