We are using the default 'SonarQube way' quality gate, which has a 'Mutations Coverage' setting, however this does not seem to cause the gate to fail.
For example, I have a small test project that does not have enough mutation coverage, and reports this as a code smell:
3 more mutants need to be covered by unit tests to reach the minimum threshold of 65% mutant coverage
This comes from a FindBugs quality profile. Is it possible also to fail a quality gate?
