I have been trying for days to get acceptance tests working but have been unsuccessful.
I think I have set everything up correctly, I have been over it many times.
I can start the phpbrowser but I am still getting the following error:
Can't be on page "/frontend/web/index-test.php/site/about": yii\base\ErrorException: Argument 3 passed to GuzzleHttp\Client::request() must be of the type array, string given, called in /Applications/MAMP/htdocs/accserv/vendor/guzzlehttp/guzzle/src/Client.php on line 87 and defined
I can even go to:
in my web browser and it works, but I am still getting the abvoe error.
Does anyone have any idea what the problem could be?
