Behat Screenshot Extension

Behat extension and step definitions to create HTML and image screenshots on demand or when tests fail.

Features

• Create a screenshot using I save screenshot or save screenshot step definition.
• Create a screenshot when test fails.
• Screenshot is saved as HTML page for Goutte driver.
• Screenshot is saved as both HTML and PNG image for Selenium driver.
• Screenshot directory can be specified through environment variable BEHAT_SCREENSHOT_DIR (useful for CI systems to override values in behat.yml).
• Screenshots can be purged after every test run by setting purge: true ( useful during test debugging) or setting environment variable BEHAT_SCREENSHOT_PURGE=1.
