Question

我最近将Grails 1.3.7项目升级到Grails 2.0.4并注意到我的许多单元测试已经开始失败。 Controller测试似乎传递得很好，当您让服务彼此协作并尝试模拟对协作者的调用时，就会出现问题。关于它的一个奇怪的部分是，如果我运行单个测试，它会通过，但是一旦我运行整个套件，它们就会失败并给出错误：

No more calls to 'getName' expected at this point. End of demands.
junit.framework.AssertionFailedError: No more calls to 'getName' expected at this point. End of demands.

我甚至尝试使用GMock而不是新的MockFor（），但是得到了类似的错误：

No more calls to 'getSimpleName' expected at this point. End of demands.
junit.framework.AssertionFailedError: No more calls to 'getSimpleName' expected at this point. End of demands.

这是一个人为的例子，展示了如何在https://github.com/punkisdead/FunWithMocks复制我正在获得的错误以及GitHub上的整个示例项目。有关如何使这项工作的任何想法？

BarController：

package funwithmocks

class BarController {

  def barService
  def fooService

  def index() { }
}

BarService：

package funwithmocks

class BarService {

  def fooService
  def bazService

  def serviceMethod() {

  }
}

BarControllerTests：

package funwithmocks

import grails.test.mixin.*
import org.junit.*
import groovy.mock.interceptor.MockFor

/**
 * See the API for {@link grails.test.mixin.web.ControllerUnitTestMixin} for usage instructions
 */
@TestFor(BarController)
class BarControllerTests {

  def fooService
  def barService

  @Before
  public void setUp() {
    fooService = new MockFor(FooService)
    fooService.use {
      controller.fooService = new FooService()
    }

    barService = new MockFor(BarService)
    barService.use {
      controller.barService = new BarService()
    }
  }

  @Test
  void doSomething() {
    controller.index()
  }
}

BarServiceTests：包装funwithmocks

import grails.test.mixin.*
import org.junit.*
import groovy.mock.interceptor.MockFor

/**
 * See the API for {@link grails.test.mixin.services.ServiceUnitTestMixin} for usage instructions
 */
@TestFor(BarService)
class BarServiceTests {

  def fooService
  def bazService

  @Before
  public void setUp() {
    fooService = new MockFor(FooService)
    fooService.use {
      service.fooService = new FooService()
    }

    bazService = new MockFor(BazService)
    bazService.use {
      service.bazService = new BazService()
    }
  }

  @Test
  void callSomeService() {
    service.serviceMethod()
  }
}

你不应该将新的测试mixin与MockFor groovy类结合起来。使用MockFor方法替换所有mockFor实例。
