Create test option not present

Hello,

I am working on a classic ruby project using rspec.

when I am in a file with a test file associated with it using Ctrl + Shift+ t send me to the test. So the link between files and tests is working.

But when I am in a file without test, if if use Ctrl + Shift+ t I just get this message

But no options to generate test. So I have to go and create the test manually.

If I read the documentation :

1. From the main menu, select Navigate | Test or press Ctrl+Shift+T.

2. If the corresponding test doesn't exist, the Generate Test popup appears. Select the required testing framework and press Enter.
   
   

A popup should appear, Rspec is installed and working.

What am I missing ? 

Is there an option I need to activate to be able to create tests from files ?

Sincerely,

Luc
