Selenium/Ruby/Target beta cluster
(Redirected from Selenium/Target beta cluster)
 | This page is obsolete. It is being retained for archival purposes. It may document extensions or features that are obsolete and/or no longer supported. Do not rely on any information on this page. See Selenium instead. |
For this example, we will target English Wikipedia at the Beta Cluster. You will need internet access.
Advantages[edit]
- You do not have to install or learn how to use MediaWiki-Vagrant.
- It will also be reasonably fast.
- MediaWiki core Selenium test run takes about 3 minutes on my machine.
- It takes about 6-7 minutes for selenium-Core Jenkins job to run.
- Debugging failed tests will be easier, since you will see the browser.
Disadvantages[edit]
- You will need internet connection while running the tests.
- The tests will be slower since the target machine is not local.
- You will have to install Selenium and it's dependencies on your machine.
- While the tests are running the host machine will be hard to use because Chrome will be opening and closing for every test (but not stealing focus).
Clone MediaWiki core[edit]
There are several ways to clone the MediaWiki core repository (anonymous http, http, ssh). We will use anonymous http since it is the simplest.
$ git clone https://gerrit.wikimedia.org/r/mediawiki/core mediawiki
Cloning into 'core'...
...
Checking out files: 100% (6426/6426), done.
Go to mediawiki folder[edit]
$ cd mediawiki
Install dependencies[edit]
Depending on your operating system, installing dependencies will be different.
Chrome[edit]
- Install Chrome.
- Download ChromeDriver and put it in a folder included in
PATH.
Ruby[edit]
Installing Ruby might be easier, or harder.
- On Linux, please use appropriate package manager.
- On Windows, please use RubyInstaller.
- It should already installed on Mac machines.
- Ruby 2.0 or newer is required.
- Third-party tools like rbenv or RVM are not required.
After installation, check if everything is all right.
$ ruby -v
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-darwin15]

$ gem install bundler --no-rdoc --no-ri

Use `bundle show [gemname]` to see where a bundled gem is installed.
Create an account at the beta cluster[edit]
You can skip this step if you already have an account there. If not, create an account at English Wikipedia at the Beta Cluster.
