We leave internationalization to the eclipse tooling. As a general rule, we have found it is good for people to treat generated tests the same as they treat hand-written ones and so should use the same coding standards, etc. Since there are multiple ways to handle internationalization, we thought it better to leave this to the developer rather than bake it in (in case we broke some of their assumptions). That said, a common practice is to externalize strings generated in tests using the standard "Externalize Strings" wizard. Is this the appropriate approach for you? Would it be an improvement if our code generation optionally triggered this wizard?
