W3C Web Platform Tests in Blink Web Tests
Design Doc: https://goo.gl/iXUaZd
This directory contains checked out and reduced code from web-platform-tests
(https://github.com/web-platform-tests/wpt/) required to run WPT tests as part
of Blink's test infrastructure and some maintenance/configuration code.
The third party code lives entirely in the wpt subdirectory:
tools/blinkpy/third_party/wpt/wpt
For licensing, see README.chromium in parent directory
(tools/blinkpy/third_party/README.chromium).
**
Files in this directory (non third-party)
README.chromium
===============
This file.
wpt.config.json
===============
The configuration file used when running WPTServe. Note that this file loads
after wpt/config.default.json and this configuration gets merged onto it. When
changing the ports (HTTP/S, WS/S), make sure to also:
- update `WPT_HOST_AND_PORTS` in
`//third_party/blink/tools/blinkpy/web_tests/port/driver.py`
- update WebTestContentBrowserClient::GetOriginsRequiringDedicatedProcess()
checkout.sh
===========
Running this script without arguments will remove the existing checkout
(third_party/wpt/wpt) and perform a fresh one. See "Rolling in WPT" for more.
WPTWhiteList
============
The explicit list of files being kept, everything else not on this list is
deleted when running "./checkout.sh reduce". Use this file to control what gets
checked in and try to keep the list as small as possible (use what you need).
certs/
======
This directory contains a private key and a certificate of WPTServe, and files
for self-signed CA. By default, WPTServe generates these files using the
"openssl" command, but we check in pre-generated files to avoid "openssl"
dependency.
These certificates will expire in January 2025. Here is an instruction to
re-generate them:
1. Make sure the following commands are in $PATH.
- base64
- git
- grep
- openssl
- sed
2. Run update_certs.py
3. Look at the "Not After" date in the output of the command, and update
"January 2025" in this document and expiration_date in wptserve.py to new
expiration date.
4. Update certs/127.0.0.1.sxg.*.
Please refer to
third_party/blink/web_tests/http/tests/loading/sxg/resources/README.md
5. git commit
6. git cl upload, etc.
**
Rolling in WPT
If there are new files that need to be rolled in, add the intended files to
the WPTWhiteList. Ensure these files are in the correct order by running
"LC_ALL=C sort WPTWhiteList".
When rolling in new versions of WPT support, modify WPT_HEAD in checkout.sh to
the desired HEAD position. You can then call "./checkout.sh clone" which will
pull in all the code.
It is also important to update the hashes in the 'Version:' fields of
tools/blinkpy/third_party/README.chromium.
You can examine what's pulled in and update WPTWhiteList if some new files are
required to run the updated version.
Once you've cloned the repositories you can call "./checkout.sh reduce" to
remove everything that is not listed in WPTWhiteList.
Note that calling "./checkout.sh" without arguments is equivalent of calling
"./checkout.sh clone reduce".
**
Configuration
Read instructions in WPT README:
https://github.com/web-platform-tests/wpt/blob/master/README.md
Also, check out the WPTServe Documentation
(https://wptserve.readthedocs.org/en/latest/).
Note that editing /etc/hosts is not required for run_web_tests.py since
content_shell is invoked with flags to map all *.test domains to 127.0.0.1.
**
Running web-platform-tests with enabled WPTServe on a local machine
WPTServe is now enabled by default in run_web_tests.py for tests that live in
web_tests/external/wpt.
WPTServe starts HTTP/S and WS/S servers as separate processes.
The content_shell used to run the tests will receive the URL of each test
(instead of a filename). The document root http://web-platform.test/ maps to
web_test/external/wpt. HTTPS tests are enabled by default.
Example run:
./tools/run_web_tests.py external/wpt
