After I run $ php admin/tool/behat/cli/util.php --enable I see this message:
Acceptance tests environment enabled on http://127.0.0.1, to run the test use:
vendor/bin/behat --config /var/www/education/moodle/admin/tool/behat/cli/tests/behat/behat/behat.yml
Then I run my behat feature file:
vendor/bin/behat --config /var/www/education/moodle/admin/tool/behat/cli/tests/behat/behat/behat.yml local/intelliboard/tests/behat/student_dashboard.feature
Its message to me:
Behat only can run if test mode is enabled. More info in http://docs.moodle.org/dev/Acceptance_testing#Running_tests
I read that doc a lot, there is no any info to solve my issue, because I did util.php --enable and even check a behat.yml and found my student_dashboard.feature test and context variable and related for it .php filename with test steps.
I even install NodeJS Gherkin validator and check my feature for errors - its clean.
