 * 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`.
