To make use of Behat, we first have to install it on our system. Read more about Behat installation in official documentation.
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. 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 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, actions to be performed before launch).
4. If you haven't configured path to Behat directory or behat.phar file before, PhpStorm will offer you to do so with a Fix button in the run configuration dialog. Provide 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, configuration 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 action 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 source of the test, sort or filter results of tests, and much more.
Resolve from step in Gherkin file to Context file
Hover step in Gherkin file with Ctrl / Cmd hotkey pressed and get relevant method from the Context file highlighted. Clicking on appeared link immediately navigates you to the declaration. You can also navigate to the method declaration in the Context file with Ctrl+B / Cmd-B with an editor caret placed at the step in Gherkin file.
As soon as 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 the method in all *.feature files. Just place a caret at the method name and invoke Alt-F7 (or context menu action Find Usages). You will see all the usages of desired method in project files:
Keyword and step completion
All the keywords and steps are completed with a basic code completion action (Ctrl+Space) in *.feature files. All the steps are indexed from current project and always up-to-date.
Generation for undefined steps
If any of steps in your *.feature file are undefined, the PhpStorm will spot that in a moment highlighting step in question with undefined step reference inspection result:
Press Alt+Enter (or click on the light bulb) to get list of relevant quick fixes, and select the one named Create Step Definition.
You will be immediately offered to choose step definition file from your project or create a new one.
In case of choosing already existing step definition file, step definition will be immediately created there with relevant PHPDoc:
In case you would like to create a new file, this option should be selected from the list on the previous step:
Create New Step Definition File dialog will appear providing you an opportunity to set a file name, file type and file location:
As soon as you are done with these options, a new step definition file will be created:
