Selenium/How-to/Run tests targeting Quibble

From mediawiki.org

This page describes how to run Selenium tests locally against your own Quibble MediaWiki install.

Advantages

[edit]
  • It will be fast, since the target machine is local. MediaWiki core Selenium test run takes about 3 minutes on my machine. (As of March 2020.)
  • Works without an internet connection.
  • Doesn't require installing ChromeDriver or FFmpeg (compared to bare installs).
  • Doesn't require executing npm packages directly on your machine (which is scary).

Disadvantages

[edit]
  • You need to have Docker installed.

Prerequisites

[edit]

Setup Quibble

[edit]
docker pull docker-registry.wikimedia.org/releng/quibble-stretch-php72:latest
git clone "https://gerrit.wikimedia.org/r/integration/quibble"
cd quibble
mkdir -p ref/mediawiki/skins
git clone --bare https://gerrit.wikimedia.org/r/mediawiki/core ref/mediawiki/core.git
git clone --bare https://gerrit.wikimedia.org/r/mediawiki/vendor ref/mediawiki/vendor.git
git clone --bare https://gerrit.wikimedia.org/r/mediawiki/skins/Vector ref/mediawiki/skins/Vector.git
mkdir cache
chmod 777 cache
mkdir -p log
chmod 777 log
mkdir -p src
chmod 777 src
docker run -it --rm \
  -v "$(pwd)"/cache:/cache \
  -v "$(pwd)"/log:/workspace/log \
  -v "$(pwd)"/ref:/srv/git:ro \
  -v "$(pwd)"/src:/workspace/src \
  docker-registry.wikimedia.org/releng/quibble-stretch-php72:latest
If you get PHP Fatal error error, you can continue with the next step. It should work. See phab:T278707.

Run Selenium tests

[edit]
docker run -it --rm \
  -v "$(pwd)"/cache:/cache \
  -v "$(pwd)"/log:/workspace/log \
  -v "$(pwd)"/ref:/srv/git:ro \
  -v "$(pwd)"/src:/workspace/src \
  docker-registry.wikimedia.org/releng/quibble-stretch-php72:latest \
  --skip-zuul \
  --skip-deps \
  --run selenium

Log files are located in log folder, including videos of all tests.
