* 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.
* Bump to 0.2.12
* Update all version numbers and deps
* Update all listed authors to `["The wasm-bindgen Developers"]`
* Update `repository` links to specific paths for each crate
* Update `homepage` links to the online book
* Update all links away from `alexcrichton/wasm-bindgen`
* Add `#[doc]` directives for HTML URLs
* Update more version requirements
* Fill out CHANGELOG
* Move the `js` module to a `js_sys` crate
* Update js-sys tests to pass again
* Update binding_to_unimplemented_apis_doesnt_break_everything
Remove its dependency on the `js` module
* Update metadata for js-sys
* Fix the `closures` example
* Create a new `web-sys` crate
This will eventually contain all the WebIDL-generated bindings to Web APIs.
* ci: Test the new `web-sys` crate in CI
* web-sys: Add a small README
* web-sys: Vendor all the WebIDL files from mozilla-central
* backend: Add a pass to remove AST items that use undefined imports
This is necessary for the WebIDL frontend, which can't translate many WebIDL
constructs into equivalent wasm-bindgen AST things yet. It lets us make
incremental progress: we can generate bindings to methods we can support right
now even though there might be methods on the same interface that we can't
support yet.
* webidl: Add a bunch of missing semicolons
* webidl: Make parsing private
It was only `pub` so that we could test it, but we ended up moving towards
integration tests rather than unit tests that assert particular ASTs are parsed
from WebIDL files.
* webidl: Remove uses of undefined import types
* test-project-builder: Build projects in "very verbose" mode
This helps for debugging failing WebIDL-related tests.
* test-project-builder: Add more profiling timers
* test-project-builder: Detect when webpack-dev-server fails
Instead of going into an infinite loop, detect when webpack-dev-server fails to
start up and early exit the test.
* webidl: Specify version for dev-dependency on wasm-bindgen-backend
Instead of only a relative path.
* guide: Add section about contributing to `web-sys`
* WIP enable Event.webidl
Still need to fix and finish the test.
* Update expected webidl output
* Start out a test's status as incomplete
That way if we don't fill it in the error message doesn't look quite so bizarre
* Fix onerror function in headless mode
Otherwise we don't see any output!
* Fix package.json/node_modules handling in project generation
Make sure these are looked up in the git project root rather than the crate root
* Avoid logging body text
This was meant for debugging and is otherwise pretty noisy
* Fix a relative path
* More expected test fixes
* Fix a typo
* test-project-builder: Allow asynchronous tests
* webidl: Convert [Unforgeable] attributes into `#[wasm_bindgen(structural)]`
Fixes#432
* test-project-builder: Print generated WebIDL bindings for debugging purposes
Helps debug bad WebIDL bindings generation inside tests.
* When we can't find a descriptor, say which one can't be found
This helps when debugging things that need to become structural.
* web-sys: Test bindings for Event
* ci: Use `--manifest-path dir` instead of `cd dir && ...`
* web-sys: Just move .webidl files isntead of symlinking to enable them
* tests: Polyfill Array.prototype.values for older browsers in CI
* test-project-builder: Don't panic on poisoned headless test mutex
We only use it to serialize headless tests so that we don't try to bind the port
concurrently. Its OK to run another headless test if an earlier one panicked.
* JsValue: Add {is,as}_{object,function} methods
Allows dynamically casting values to `js::Object` and `js::Function`.
* tidy: Fix whitespace and missing semicolons
* Allow for dynamic feature detection of methods
If we create bindings to a method that doesn't exist in this implementation,
then it shouldn't fail until if/when we actually try and invoke that missing
method.
* tests: Do feature detection in Array.prototype.values test
* Add JsValue::{is_string, as_js_string} methods
And document all the cast/convert/check methods for js value.
* eslint: allow backtick string literals
* Only generate a fallback import function for non-structural imports
The WebIDL-based -sys crate will also use this, but I want its tests to be a
separate suite that we can run separately and in parallel in CI. Therefore, this
testing infrastructure code needs to be share-able between them :)
* tests: Add newlines between impl methods for Project
* WIP headless browser testing with geckodriver and selenium
* Get some more of headless testing working
* Extract `console.log` invocations and print them from the console
* Ship the error message from an exception from the browser back to the command
line
* Cleanup some "if headless" and `else` branches
* Fix killing `webpack-dev-server` in the background with `--watch-stdin`
* Fix path appending logic for Windows
* Always log logs/errors in headless mode
* Install Firefox on Travis
* Don't duplicate full test suite with `yarn`
No need to run that many tests, we should be able to get by with a smoke test
that it just works.
* headless tests: Move `run-headless.js` to its own file and `include_str!` it
* Run `rustfmt` on `tests/all/main.rs`
* guide: Add note about headless browser tests and configuration
* test: Log WASM_BINDGEN_FIREFOX_BIN_PATH in run-headless.js
* TEMP only run add_headless test in CI
* Add more logging to headless testing
* Allow headless tests to run for 60 seconds before timeout
* TEMP add logging to add_headless test
* Fix headless browser tests
* Another attempt to fix Travis
* More attempts at debugging
* Fix more merge conflicts
* Touch up an error message
* Fixup travis again
* Enable all travis tests again
* Test everything on AppVeyor
These are bindings to JavaScript's standard, built-in objects and their methods
and properties.
This does *not* include any Web, Node, or any other JS environment APIs. Only
the things that are guaranteed to exist in the global scope by the ECMAScript
standard.

* Add comments test
* Update readmes
* add comments to travis
* fix broken tests
* +x on build.sh
* fix wbg cmd in build.sh
* Address fitzgen's comments
This is still a work in progress. Parse WebIDL source text and convert it into
wasm-bindgen AST, so that we can automatically emit bindings for the types and
functions described in the WebIDL.
This commit adds an example of executing the `wasm2asm` tool to generate asm.js
output instead of WebAssembly. This is often useful when supporting older
browsers, such as IE 11, that doesn't have native support for WebAssembly.
These functions are activated with the `serde-serialization` feature of the
`wasm-bindgen` crate. When activated they will allow passing any arbitrary value
into JS that implements the `Serialize` trait and receiving any value from JS
using the `Deserialize` trait. The interchange between JS and Rust is JSON.
Closes#96
Using `proc-macro2`'s `nightly` feature is a good default for most use cases.
However, it causes a build error if used together with crates such as
`cssparser` that also use `proc-macro2` from a build script.
This change adds a default enabled feature `spans` that users can disable if
they need to work around this conflict.
Fixes#160.
This commit adds support for both `#![no_std]` in the wasm-bindgen runtime
support (disabled by default with an on-by-default `std` feature). This also
adds support to work and compile in the context of `#![no_std]` crates.
Closes#146
Nowadays the compile times are mitigated with incremental compilation and
otherwise it's much more ergonomic to run only one test if they're all in the
same suite.
Right now Webpack probably has the most mature support for loading wasm modules,
so let's show off how to do that! Additionally this commits hello world as an
example to the repository.
