Lightpanda is tested against the standardized [Web Platform
Tests](https://web-platform-tests.org/).
The relevant tests cases are committed in a [dedicated repository](https://github.com/lightpanda-io/wpt) which is fetched by the `make install-submodule` command.
All the tests cases executed are located in the `tests/wpt` sub-directory.
We use [a fork](https://github.com/lightpanda-io/wpt/tree/fork) including a custom
[`testharnessreport.js`](https://github.com/lightpanda-io/wpt/commit/01a3115c076a3ad0c84849dbbf77a6e3d199c56f).
For reference, you can easily execute a WPT test case with your browser via
[wpt.live](https://wpt.live).
#### Configure WPT HTTP server
To run the test, you must clone the repository, configure the custom hosts and generate the
`MANIFEST.json` file.
Clone the repository with the `fork` branch.
```
git clone -b fork --depth=1 git@github.com:lightpanda-io/wpt.git
```
Enter into the `wpt/` dir.
Install custom domains in your `/etc/hosts`
```
./wpt make-hosts-file | sudo tee -a /etc/hosts
```
Generate `MANIFEST.json`
```
./wpt manifest
```
Use the [WPT's setup
guide](https://web-platform-tests.org/running-tests/from-local-system.html) for
details.
#### Run WPT test suite
To run all the tests:
An external [Go](https://go.dev) runner is provided by
[github.com/lightpanda-io/demo/](https://github.com/lightpanda-io/demo/)
repository, located into `wptrunner/` dir.
You need to clone the project first.
First start the WPT's HTTP server from your `wpt/` clone dir.
```
./wpt serve
```
Run a Lightpanda browser
```
make wpt
zig build run
```
Then you can start the wptrunner from the Demo's clone dir:
```
cd wptrunner && go run .
```
Or one specific test:
```
make wpt Node-childNodes.html
cd wptrunner && go run . Node-childNodes.html
```
#### Add a new WPT test case
`wptrunner` command accepts `--summary` and `--json` options modifying output.
Also `--concurrency` define the concurrency limit.
We add new relevant tests cases files when we implemented changes in Lightpanda.
:warning: Running the whole test suite will take a long time. In this case,
it's useful to build in `releaseFast` mode to make tests faster.
To add a new test, copy the file you want from the [WPT
repo](https://github.com/web-platform-tests/wpt) into the `tests/wpt` directory.
:warning: Please keep the original directory tree structure of `tests/wpt`.
```
zig build -Doptimize=ReleaseFast run
```
