Cypress: Run all specs but create a loop without run specs

I have a problem with Cypress.io, here is my problem :

I have 4 different test files here :

integration/socle_full_ts_dev/1_register_user.spec.js

/// <reference types="cypress" />

    });
});

And the problem that I meet is that when I want to launch all the tests at the same time it turns in a loop and does not get out of it. I checked the web to see if someone had already had the problem and I didn't find ... here is a video demonstrating the problem :

Here is what i tried :

• To put tests standby with xit
• Look in the documentation if there was anything to do with memory allocation...
• Separate tests with folders

My tests are not that complicated I just test the registration of a user and the login of the same user...

If someone has an idea ? Thanks :)
