Swagger-codegen version

3.0.0

Start by reproducing the Maven plugin's generate goal with the configuration shown, especially generateApiTests=false, and inspect the Java generator's handling of that option. Done means the generated sources contain no API test classes while the other configured generation options still behave as expected.
