Step 1: Make sure Selenium2Driver is installed using Composer, you can check your composer file for that. Otherwise execute below command.
$ composer require --dev behat/mink-selenium2-driver
Step 2: Download Selenium Server from Here, click on latest stable version.
Step 3: Check you browser version and check it is compatible with which driver from here.
Step 4: Download Firefox gecko compatible with your browser and OS from Here.
Step 5: Run below command in the directory where you have downloaded your server and firefox file otherwise you can give the path of directory. For me both files are in same directory.
$ java -Dwebdriver.gecko.driver=geckodriver -jar selenium-server-standalone-3.141.59.jar
Step 6: Make sure your behat.yml is configure properly. Selenium2 driver is enabled, default session is set and browser name is added. For firefox you can skip browser_name. By default it starts on firefox.
#behat.yml default: suites: default: paths: features: features bootstrap: 'features/bootstrap' contexts: - Behat\MinkExtension\Context\MinkContext extensions: Behat\MinkExtension: goutte: ~ selenium2: ~ browser_name: firefox default_session: selenium2 base_url: http://automationpractice.com
