===============
Mutant found no tests available for mutation testing.
Mutation testing cannot be started.
This can have various reasons:
* You did not setup an integration, see:
https://github.com/mbj/mutant/blob/main/docs/configuration.md#integration
* You set environment variables like RSPEC_OPTS that filter out all tests.
* You set configuration optiosn like `config.filter_run :focus` which do
make rspec to not report any test.
