Describe the current, buggy behavior
Running the "Skip a theme using block patterns with Gutenberg active" test currently throws this warning:
Warning: The package could not be installed. "The PHP version on your server is 7.0.33-68+ubuntu20.04.1+deb.sury.org+2, however the uploaded plugin requires 7.2."
Warning: The 'gutenberg' plugin could not be found.
Describe what you expect as the correct outcome
The test should now break with a warning.
