Monitoring and Security Center "failures" show synth output, not tests.

@busunkim96 Nothing actually tests the generated samples, but since we have other untested ones, it doesn't seem like a blocker here.

@tseaver, the generated samples may be tested by sample-tester, based on YAML files available at https://github.com/googleapis/googleapis/tree/master/google/cloud/datacatalog/v1beta1/samples.

[tseaver]

@ricardosm-cit Where would failures be reported by samples-tester?

[ghost]

Sorry @tseaver, I don't know. Maybe @busunkim96 can help with this.

I just talked to Rebecca -- it sounds like the sample-tester isn't quite ready. Synthtool will be updated to run sample tests using sample-tester soon. We can leaves these untested for the time being.
