下一个测试失败,java.NullPointerException
package org.ttm
import grails.test.mixin.TestFor
import spock.lang.Specification
@TestFor(ActorController)
class ActorControllerSpec extends Specification {
StageDataService stageDataService = Mock()
void setup() {
controller.stageDataService = stageDataService
}
void 'index returns list of stages'() {
Long id = 20
when:
controller.index(id)
then:
1 * stageDataService.getActors(id)
}
}
这里有什么问题?
这是StackTrace:

好的,我认为这可能是问题所在:http://jira.grails.org/browse/GRAILS-10538。我的控制器使用grails.transaction.Transactional
标记进行修饰。解决方法是使用@Mock
标记模拟一个类。 Holly Molly Bugs。
答案 0 :(得分:0)
很难说没有堆栈跟踪或任何内容,但1 * StageDataService.getActors(id)
肯定应该是1 * stageDataService.getActors(id)
。
