You can execute tests using Phpunit directly :
UserFrosting's built-in integration tests use a temporary in-memory SQLite database. For testing to run successfully, you must have the
php-sqlite3 package installed and enabled. Alternatively, you can create a separate testing database and override the
test_integration database settings in the
testing.php environment mode from your site sprinkle.
When testing, only the tests define in your Sprinkle will be run. UserFrosting base system tests are run in their own repository.
