Behat tests for Neos¶
Setting up Neos for running Behat tests¶
The Neos package contains a growing suite of Behat tests which you should take into account while fixing bugs or adding new features. Please note that running these tests require that the Neos demo site package (TYPO3.NeosDemoTypo3Org) is installed and activated.
Install Behat for the base distribution¶
Behat is installed in a separate folder and has a custom composer root file. To install Behat run the following composer command in FLOW_ROOT/Build/Behat:
cd Build/Behat composer install
A special package Flowpack.Behat is used to integrate Flow with Behat and is installed if the base distribution was installed with composer install –dev.
Create configuration for subcontexts¶
Behat needs two special Flow contexts, Development/Behat and Testing/Behat.
- The context Development/Behat should be mounted as a separate virtual host and is used by Behat to do the actual HTTP requests.
- The context Testing/Behat is used inside the Behat feature context to set up test data and reset the database after each scenario.
These contexts should share the same database to work properly. Make sure to create a new database for the Behat tests since all the data will be removed after each scenario.
TYPO3: Flow: persistence: backendOptions: dbname: 'neos_testing_behat'
TYPO3: Flow: persistence: backendOptions: dbname: 'neos_testing_behat' driver: pdo_mysql user: '' password: ''
Example virtual host configuration for Apache:
<VirtualHost *:80> DocumentRoot "FLOW_ROOT/Web" ServerName neos.behat.test SetEnv FLOW_CONTEXT Development/Behat </VirtualHost>
The Behat tests for Neos are shipped inside the TYPO3.Neos package in the folder Tests/Behavior. Behat uses a configuration file distributed with Neos, behat.yml.dist, or a local version, behat.yml. To run the tests, Behat needs a base URI pointing to the special virtual host running with the Development/Behat context. To set a custom base URI the default file should be copied and customized:
cd Packages/Application/TYPO3.Neos/Tests/Behavior cp behat.yml.dist behat.yml # Edit file behat.yml
default: paths: features: Features bootstrap: %behat.paths.features%/Bootstrap extensions: Behat\MinkExtension\Extension: files_path: features/Resources show_cmd: 'open %s' goutte: ~ selenium2: ~ base_url: http://neos.behat.test/
java -jar selenium-server-standalone-2.x.0.jar
If using Saucelabs, you do not need your own Selenium setup.
Running Behat tests¶
Behat tests can be run from the Flow root folder with the bin/behat command by specifying the Behat configuration file:
bin/behat -c Packages/Application/TYPO3.Neos/Tests/Behavior/behat.yml
In case the executable file bin/behat is missing, create a symlink by running the following command in FLOW_ROOT/bin:
ln -s ../Build/Behat/vendor/behat/behat/bin/behat
You might want to warmup the cache before you start the test. Otherwise the tests might fail due to a timeout. You can do that with FLOW_CONTEXT=Development/Behat ./flow flow:cache:warmup.
- Make sure to use a new database and configure the same databse for Development/Behat and Testing/Behat
- Run Behat with the -v option to get more information about errors and failed tests
- A failed step can be inspected by inserting “Then show last response” in the .feature definition
Run Behat tests on several browsers using Saucelabs¶
Make sure that your Behat version is uptodate. Otherwise the saucelabs connection won’t work. The behat/mink-extension need to be at least version 1.3.
Saucelabs (http://saucelabs.com) provides a VM infrastructure you can use to run your selenium tests on.
To run Neos Behat tests with saucelabs you need to do the following steps.
To talk to saucelabs you need to uncomment the following lines in the behat.yml and add your saucelabs username and access_key:
Saucelabs provides unlimited video time for TYPO3 core development. If you want to contribute to Neos by writing tests ask Christian Müller.
To make tests with more browsers than the default browser you need to tell saucelabs which browser, version and OS you want to test on. You can add several browsers, each in its own profile. There are a lot of browsers configured already in the saucelabsBrowsers.yml file. You can include that into your behat configuration:
imports: - saucelabsBrowsers.yml
Open a tunnel to saucelabs¶
If you want to run the tests on your local machine you need to open a tunnel to saucelabs. This can be easily done by downloading Sauce Connect at https://docs.saucelabs.com/reference/sauce-connect/ and follow the instructions to setup and start it.
Run Behat tests¶
A test with Internet Explorer 10 on Windows8 would look like this then:
bin/behat -c Packages/Application/TYPO3.Neos/Tests/Behavior/behat.yml --profile windows8-ie-10
The possible configuration settings for browsers can be found at https://saucelabs.com/docs/platforms. Choose “WebDriver” and “php” and click on the platform/browser combination you are interested in.
