Testing Area/Behat Testing/Setup
From Mahara Wiki
< Testing Area | Behat Testing
1. Set up your developer environment if you haven't already done so.
2. Install Behat's dependencies:
$ sudo apt-get install curl openjdk-8-jre-headless
3. Add the following config settings to the bottom of your Mahara config.php file inside the htdocs/ subdirectory of the Mahara codebase.
// Behat config
$cfg->behat_dbprefix = 'behat_'; // must not empty
$cfg->behat_dataroot = "/var/lib/maharadata/master_behat"; // Behat's copy of maharadata
$cfg->behat_wwwroot = 'http://localhost:8000'; // Must be this
$cfg->behat_selenium2 = "http://127.0.0.1:4444/wd/hub"; // Must be this
4. Make your Behat data directory (check this matches what you set in config.php):
$ sudo mkdir /var/lib/maharadata/master_behat
5. Make the directory and any subdirectories writeable by Mahara (check this is correct):
$ sudo chmod 777 -R /var/lib/maharadata/master_behat
6. Change the directory and any subdirectories permissions to be owned by apache user (check this is correct):
$ sudo chown -R www-data.www-data /var/lib/maharadata/master_behat
- For Ubuntu, apache runs with user www-data
- For Centos, apache runs with user apache
7. Run Behat tests (change into your Mahara code directory first) as the apache user:
$ cd
$ cd code/mahara
./test/behat/mahara_behat.sh run
Or if you have sudo access:
$ cd
$ cd code/mahara
sudo -u www-data ./test/behat/mahara_behat.sh run
For the first time of running Behat, you need to wait for the Behat environment initialisation. This can take a while.
To run all tests:
./test/behat/mahara_behat.sh run
To run your specific tests marked with @yourtags:
./test/behat/mahara_behat.sh run @yourtags
To run a particular feature file:
./test/behat/mahara_behat.sh run my_file.feature
The run / runheadless / rundebug / rundebugheadless / runfresh are interchangable with run in above commands
Running Behat tests with html report and screenshots on failed steps
To run tests with html output, add the flag 'html' to your test run command, e.g:
./test/behat/mahara_behat.sh run create_page.feature html
This will automatically open an html report of the test run in your browser. If there were failed steps, the the html report plugin takes a screenshot of the page that failed. You can find the screenshots in your behat dataroot (usually /var/lib/maharadata/master_behat) at the following path: behat/html_results/<feature title>/<scenario title>.png
Hopefully we will rig up the report to link to the screenshot soon.
How to Run Mahara behat test on Chrome
This is steps for older versions of Mahara
1. Download chromedriver here http://www.seleniumhq.org/download/ ( download the latest release)
2. Start selenium Server with chrome driver
$ java -jar selenium-server-standalone-2.53.1.jar -Dwebdriver.chrome.driver=path of chromedriver
3. Change the behat.yml file as follows,
Here is the file path var/lib/maharadata/master_behat/behat.yml
when you open the beaht.yml file replace the following code with the lines that contain sessions to goutte=NUll( Niranjan or Lovesh can exactly tell you where to replcae the code if it is confusing) and save it
javascript_session: selenium2
selenium2: browser: chrome goutte: ~
4. Run the behat test without rundebug
for example ./test/behat/mahara_behat.sh run example.feature
Debugging
In some cases, depending on the version of Ubuntu you have, the wrong version of OpenJDK will be installed. Selenium only runs with OpenJDK 8, but Ubuntu Bionic tends to install OpenJDK 11 (especially if 'default-jre' was installed)
If you run into issues where the script says it has started Selenium, but that Behat throws an exception because it thinks Selenium has not started, check the JRE installed:
java -version
If it says you're using OpenJDK 10 or 11 (which can ship with Ubuntu 18.04 depending on which service pack is used), this needs to be uninstalled first:
sudo apt-get remove openjdk*
Once this is removed, you will need to re-run the OpenJDK 8 installation:
$ sudo apt-get install openjdk-8-jre-headless
