You should get an error, like: FeatureContext context class not found and can not be used Now that you have the tools installed, you should have a behat command available. In layman's terms, Mink allows you to control a browser programmatically to emulate a user's action. Mink allows you to write a test once and execute it in different browser emulators. There are various browser emulators, such as Goutte and Selenium, and they all behave differently and have very different APIs. It helps to keep Drupal development team members in the loop from the word go.Because these tests are supposed to emulate user interaction, you can assume they will be executed within a web browser. Communication: The auto-testing framework supports collaboration on testing, test results, and corrective actions every step of the way.Simultaneous testing: With Behat, you can perform simultaneous tests across multiple devices/platforms with thousands of virtual users.That improves the credibility of the test results. Precision: Behat supports the precise execution of repetitive tests.Automated BDD testing solves the problem. Extended coverage: With the manual approach, you might not cover all the web app features that require lengthy testing considering the time and labor costs involved.Automated repetitive test runs: These help to save time and money compared to the cost of a human-centric process.Winding Up: The Key Benefits of Automated Testing With BehatĪutomated BDD testing with Behat in Drupal offers the following perks: Likewise, the testing team can use "Scenario Outline" to run a single test with different values many times over. In Behat, feature scenarios describe the business expectations that are subject to testing. The tool is also ideal for regression testing to check the functionality of a newly added feature or updated website. It also enables unlimited code reusability.Īutomated Behat tests can detect issues at an early stage of web app development. So, it reduces maintenance time in case of any updates to the web app. Mink also supports the Page Object Model. Users require no coding skills to add these to functional tests. One thing that makes Mink easy to use is the predefined steps. The extension is ideal for both real and headless browsers. "Then" defines the outcome of the specific action, confirming the occurrence of the expected feature behavior.īehat's web application tests are based on the Mink library, and they're perfect for multi-environment testing. Here, "Given" sets up the condition to be executed before the test starts. When the user Logins using valid credentials The framework uses the Gherkin syntax of "Given," "When," and "Then." These statements are easy for the testing team to understand, edit, or add.īelow are sample Gherkin statements for an automated login test: The Behat BDD framework comes with the following features:īehat is used to write human-readable statements for automated functional and acceptance tests. Key Highlights of the Behat BDD Framework You can use this file to store mission-critical project resources, such as libraries, pages, and context files. Behat refers to the file to access the details required to test the software features in question.Īlso, the feature file you create will list all the test steps, each of which has its specific action defined in the context file. There's also a Drupal extension package that facilitates the integration of Drupal, Behat, and the Mink extension.īe sure to define your folder structure in the project root directory using the command `bin/behat –init.` To configure the project, start by creating the behat.yml file in your project's root directory. To get started with the framework, you need a resource like Composer to install and configure the tools for BDD testing. One of the main advantages of Behat is that it's easy to integrate with Drupal. Getting Started With Behat for Drupal Development The open-source tool lets you build solutions that meet or exceed clients' expectations through deliberate discovery and automated testing. If you're a PHP 5.3.1 (or greater) web application developer, you need a behavior-driven development (BDD) framework like Behat to hand. This is where the Behat automated testing framework for Drupal comes in. This way, your team avoids building on mistakes that may take a lot of time and resources to fix later on. Are you building a Drupal website that has to meet strict business requirements the first time? You need a way to embed functional and acceptance testing in the development process from the ground up.
