Behat with Selenium: Tutorial to Run Your First Test on LambdaTest

In this topic, you will learn how to configure and run your PHP automation testing scripts on LambdaTest Selenium cloud platform using PHP framework Behat.

Objective​

By the end of this topic, you will be able to:

  1. Set up an environment for testing your locally hosted web pages using Behat automation testing.
  2. Understand and configure the core capabilities required for your Selenium test suite.
  3. Run test cases in parallel using Behat with Selenium to reduce build times.
  4. Test your locally hosted pages on LambdaTest platform.
  5. Explore advanced features of LambdaTest.

Note: All the code samples in this documentation can be found in the Behat LambdaTest Repository on GitHub. You can either download or clone the repository to quickly run your tests.

Prerequisites For Running Behat Selenium Scripts​

Before you begin automation testing with Selenium and Behat, you would need to:

  • Make sure that you have the latest PHP installed on your system. You can download and install PHP using following commands in the terminal:

    • MacOS: Previous versions of MacOS have PHP installed by default. But for the latest MacOS versions starting with Monterey, PHP has to be downloaded and installed manually by using below commands:
    /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
    brew install php
    • Windows:
    sudo apt-get install curl libcurl3 libcurl3-dev php

    Note: For Windows, you can download PHP from here. Also, refer to this documentation for ensuring the accessibility of PHP through Command Prompt(cmd).

  • Download composer in the project directory (Linux/MacOS, Windows).

    Note: To use the composer command directly, it either should have been downloaded in the project directory or should be accessible globally which can be done by the command below:

    mv composer.phar /usr/local/bin/composer

Installing Selenium Dependencies and tutorial repo​

Step 1: Clone the LambdaTest’s Behat-Selenium-sample repository and navigate to the code directory as shown below:

git clone https://github.com/LambdaTest/behat-selenium-sample
cd behat-selenium-sample

Step 2: Install the composer dependencies in the current project directory using the command below:

composer install

Step 3: Set up Behat automation for your OS using composer.

php composer.phar require behat/behat

Setting up Your Authentication​

Make sure you have your LambdaTest credentials with you to run test automation scripts on LambdaTest Selenium Grid. You can obtain these credentials from the LambdaTest Automation Dashboard or through LambdaTest Profile.

Step 4: Set LambdaTest Username and Access Key in environment variables.

  • For Linux/macOS:
export LT_USERNAME="YOUR_USERNAME" export LT_ACCESS_KEY="YOUR ACCESS KEY"
  • For Windows:
set LT_USERNAME="YOUR_USERNAME" set LT_ACCESS_KEY="YOUR ACCESS KEY"

Run Your First Test​

Sample Test with Behat​

Feature: Google's Search Functionality
 
Scenario: Can find search results
 
    Given I am on "https://www.google.com/ncr"
 
    When I search for "LambdaTest"
 
    Then I get title as "LambdaTest - Google Search"

Configuration of Your Test Capabilities​

Step 5: In the test script, you need to update your test capabilities. Let us have a look at an example which will validate your LambdaTest credentials for authentication purpose. Later, the code will select the basic capabilities such as OS, browser, browser version and so on.

default:
   paths:
       features: '../features/single'
       bootstrap:  '../features/bootstrap'
   context:
       parameters:
           lambdatest:
               server: "hub.lambdatest.com"
               user: "YOUR_LAMBDATEST_USERNAME"
               key: "YOUR_LAMBDATEST_ACCESS_KEY"
 
               capabilities:
                   build: "behat-selenium-sample"
                   name: "single-behat-test"
                   video: true
                   visual: true
                   network: true
                   console: true
 
 
               environments:
                   -
                       browserName: chrome
                       version: 71.0
                       platform: Win10

Note: You can generate capabilities for your test requirements with the help of our inbuilt Capabilities Generator tool.

Executing the Test​

Step 6: The tests can be executed in the terminal using the following command:

composer single

Your test results would be displayed on the test console (or command-line interface if you are using terminal/cmd) and on LambdaTest automation dashboard. LambdaTest Automation Dashboard will help you view all your text logs, screenshots and video recording for your entire automation tests.

Running Parallel Tests Using Behat Framework​

Executing Parallel Tests Using Behat​

To run parallel tests using Behat, we would have to execute the below command in the terminal:

composer parallel

Your test results would be displayed on the test console (or command-line interface if you are using terminal/cmd) and on LambdaTest automation dashboard.

Testing Locally Hosted or Privately Hosted Projects​

You can test your locally hosted or privately hosted projects with LambdaTest Selenium grid cloud using LambdaTest Tunnel app. All you would have to do is set up an SSH tunnel using LambdaTest Tunnel app and pass toggle tunnel = True via desired capabilities. LambdaTest Tunnel establishes a secure SSH protocol based tunnel that allows you in testing your locally hosted or privately hosted pages, even before they are made live.

Refer our LambdaTest Tunnel documentation for more information.

Here’s how you can establish LambdaTest Tunnel.

Download the binary file of:

Open command prompt and navigate to the binary folder.

Run the following command:

LT -user {user’s login email} -key {user’s access key}

So if your user name is lambdatest@example.com and key is 123456, the command would be:

LT -user lambdatest@example.com -key 123456

Once you are able to connect LambdaTest Tunnel successfully, you would just have to pass on to set the tunnel value to true by adding the following line in your config files:

Tunnel Capability

 tunnel = true
Last updated on

Test across 3000+ combinations of browsers, real devices & OS.
