Hey @Maiwand,
What error do you get when you try to run the tests?

as far writing down code it is ok but when i run the tests it doesn’t bring the pop up message it just say (running tests)

Looks right to me. You may want to hit “Reset All Code” button and redo it.

If you are not , try using google chrome or Mozilla Firefox

right now I’m using mozilla firefox but i"ll try google chrome too

Check that it is last version of the browser, you need new version for this to work

okay! i guess that is the problem because i haven’t updated mozilla firefox to the latest version.
thank u guys.
