我使用的是一个非常简单的域模型，就像这样创建......
entity --class ~.domain.Contact --abstract --inheritanceType TABLE_PER_CLASS
entity --class ~.domain.Student --extends ~.domain.Contact --testAutomatically
entity --class ~.domain.Family --extends ~.domain.Contact --testAutomatically
然后我在每个班级添加几个字段......
field string --fieldName firstName --class ~.domain.Contact
field string --fieldName secondName --class ~.domain.Contact
field string --fieldName firstName2 --class ~.domain.Family
field string --fieldName secondName2 --class ~.domain.Family
然后我自动生成的测试失败。对我来说这看起来像个错误，有人看到这个方法，或者我不能在子类上使用--testAutomatically吗？ （有点垃圾！）
（我在Roo的早期阶段失去了信心，grails正在给我回电话......）
这是我的堆栈跟踪...
