From test_html to public_html

Hi!

I’m having problems moving my wordpress from the test server to the public server. I just move the files from test_html to public_html but wordpress doens’t make the connection with the database when all the files are in public_html. So I called the host service and they said that there could be a path to test.mywebsite.nl. But I cant find it in any of the files.

So if anyone has had this problem before and fixed it please tell me ??
