If you are using Behat with Selenium server and running locally, if is firing up real browser instances via web driver then it is easy to see what may be going wrong. However if you are using a headless browser such as PhantomJS this makes it impossible, unless you take screenshots when an error has occured (a failed step in your scenario)
I used a handy UCSF guide for taking screenshots with Behat 2 and updated it for Behat 3
Excellent behat package to get failure details including screenshots with minimal setup! https://github.com/forceedge01/behat-fail-aid
Hi,
Should I replace “\Behat\Testwork\Tester\Result\TestResult” in “\Behat\Testwork\Tester\Result\TestResult::FAILED” and “.$filePath.DIRECTORY_SEPARATOR.$fileName.”\n”;” in “print “Screenshot for ‘{$stepText}’ placed in “.$filePath.DIRECTORY_SEPARATOR.$fileName.”\n”;” ?
