I work closely with the CR-time coverage/enforcement tool. The tool expects 70% new line coverage. The number was chosen arbitrarily, but individual teams/managers can choose to avoid the rule or set a different threshold.
It's not ridiculous to expect some, *configurable*, amount of test coverage for newly generated code, is it?
No, reasonable levels of testing are part of the job, it's when you get hard and fast rules from leadership like "don't lower coverage, reward increasing coverage" that it starts breaking down, we had that rule and someone gamed it using the methods I described up to 100% coverage.
