Selenium is running. When running the test, the following error occurs

Running WelcomeCept ... PHP Fatal error: Cannot redeclare _generated\AcceptanceTesterActions::switchToIframe() in /var/www/html/test/tests/_support/_generated/AcceptanceTesterActions.php on line 2760
Fatal error: Cannot redeclare _generated\AcceptanceTesterActions: :switchToIframe() in /var/www/html/test/tests/_support/_generated/AcceptanceTesterActions.php on line 2760

Answer 1

The error is not related to selenium. This is a codeception issue.
generated/AcceptanceTesterActions.php is the file that is generated when you run build.
It is assembled from several parts - modules and Tester from _support
View them. perhaps the switchToIframe function is duplicated there - which is what the error says.
