grails - Grails Spock测试特定异常

Question

我正在使用Grails 2.4.5，努力使Grails描绘出不同的异常类型。

假设我要模拟以下内容:

class FooController { 
def barService
...
def fooAction() {
try {
barService.someMethod(params)
} catch(e) {
if (e instanceof FooException) { ... }
else if (e instanceof BarException) { ... }
else { ... }
}
}

给定下面的测试

    @TestFor(FooController)
    class FooControllerSpec extends Specification {
    def setup() { controller.barService = Mock(BarService) }
    void "test"() {
      given: "a mock dependency"
      1* controller.barService.someMethod(_) >> { -> throw FooException('foo') }

      when: "the action is requested"
      controller.fooAction()

      then: "expect the FooException behaviour from the action"
      // some behaviour
    }

我希望在模拟依赖项关闭中抛出FooException

但是，调试将显示以下内容:

groovy.lang.MissingMethodException: No signature of method: somePackage.FooControllerSpec$_$spock_feature_0_9_closure14.doCall() is applicable for argument types: (java.util.Arrays$ArrayList) values: [[[:]]]

这是一个错误吗？有没有办法以上述方式模拟不同的异常？

Answer 1

您需要在then块中指定行为，即:

void "test"() {
  when: "the action is requested"
  controller.fooAction()

  then: "expect the FooException behaviour from the action"
  1 * controller.barService.someMethod(_) >> { -> throw new FooException('foo') }
  response.redirectedUrl == "/some/other/path"
}
