To make use of Behat, we first have to install it on our system. Read more about Behat installation in official documentation.
Please note that PHP interpreter should have mbstring extension installed (or just compiled with --enable-mbstring option) to execute Behat tests.
Installing Behat via Composer
Use the Composer | Add dependency... context menu on your project and install behat/behat package:
Installing Behat via Phar package
You can either download behat.phar package from Behat GitHub repository manually, or automatically install it from Settings | PHP | Behat | Download behat.phar from...
Run Configuration for Behat
Behat run configurations can be set in the same way as PHPUnit’s. The usual testing workflow (running with run action, UI for running tests and displaying results) is supported.
Setting Behat run configuration via Edit Configurations... action
1. New Run Configuration for Behat can be created either in Run | Edit configurations... menu, or with the same action from the toolbar:
2. Add a new configuration with button and select Behat
3. Provide the path to the directory which contains test scenarios (/Users/user/PhpStormProjects/Behat/features in our case). Test scope can be defined as a Directory, File, Scenario or Defined in configuration file. There are many additional options which can be configured in this dialog (such as alternative Behat configuration file, test runner options, command line options, or actions to be performed before launch).
4. If you haven't configured the path to Behat directory or behat.phar file before, PhpStorm will offer you to do so with the Fix button in the run configuration dialog. Provide the path to Behat and default configuration file (if needed).
Behat configuration can be always changed in Settings | PHP | Behat.
Alternatively, you can use Behat via Remote Interpreter. The configuration process is similar with the only difference that you should have remote PHP interpreter configured.
Setting Behat run configuration via file/folder context action
Depending on your workflow, in order to create run configuration on-the-fly you can just invoke context action Create Run Configuration | Folder name (with Behat icon) _or create and run it straight away with _Run | Folder name (with Behat icon) for folders in Project Tool Window:
Same actions are available in Run | Run menu (Alt + Shift + F10 / Ctrl - Alt - R):
It works in the same way for context actions inside *.feature file in the editor (creating run configuration or running all scenarios from file or single scenario from file):
Running Behat tests and evaluating results
As stated earlier, usual testing workflow (running with run action, UI for running tests and displaying results) is supported similar to the one for PHPUnit.
That means that as soon as run configuration is created (or you are running/creating test scenarios for folder/file from the context menu action), your tests will run and results will be displayed in the test runner tab:
From the test runner tab you can navigate to the source code of the test, sort or filter results of tests, and much more.
Resolve from step in Gherkin file to Context file
Press and hold Ctrl / Cmd hotkey and hover over a step in Gherkin file: the relevant method from the Context file will be highlighted. Click on the displayed link to navigate to the declaration. You can also navigate to the method declaration in the Context file with Ctrl+B / Cmd-B when the editor caret is placed at the step in Gherkin file.
As soon as a navigation action is invoked, you are navigated to the very method in Context file (FeatureContext.php in our case):
Find Usages from Context file to usages in Gherkin files
From any Context file, you can find all the usages of a method in all *.feature files. Just place the caret at the method name and press Alt+F7 (or select Find Usages from the context menu). You will see all the usages of the desired method in project files:
Keyword and step completion
Any keywords and steps are completed with the basic code completion action (Ctrl+Space) in *.feature files. All steps are indexed from the current project and always up-to-date.
Generation for undefined steps
If any of the steps in your *.feature file are undefined, PhpStorm will detect this, and will immediately highlight the step as undefined step reference:
Press Alt+Enter (or click the light bulb) to get a list of relevant quick-fixes, then select Create Step Definition. You will be prompted to choose the step definition file from your project or create a new one.
If you choose an existing step definition file, step definition will be immediately created there with a relevant PHPDoc:
If you would like to create a new file, this option should be selected from the list on the previous step:
In the Create New Step Definition File dialog, enter the file name, file type and file location:
After as you have set these options, a new step definition file will be created:
