Question

我遵循用代码编写的旧方法，用于访问服务类中的请求对象，例如：

def someServiceMethod() {
  ....
  def webUtils = WebUtils.retrieveGrailsWebRequest()
  def request = webUtils.getCurrentRequest()
  MultipartHttpServletRequest mpr = (MultipartHttpServletRequest) request
  CommonsMultipartFile file = (CommonsMultipartFile) mpr.getFile("file")
  ....
}

这是我的serivce类的单元测试代码。

@TestFor(SomeService)
class SomeServiceSpec extends Specification {
  void "test someServiceMethod"() {
    given:
    MockMultipartHttpServletRequest request = new MockMultipartHttpServletRequest()

    FileInputStream inFile = new FileInputStream("./test-data/Hiearchy-003.xlsx") //valid file path
    def multipartFile = new GrailsMockMultipartFile('file', 'file.xls', 'multipart/form-data', inFile)
    request.addFile(multipartFile)
    GrailsWebRequest webRequest = new GrailsWebRequest(
            request,
            new MockHttpServletResponse(),
            new MockServletContext()
    )
    request.setAttribute(GrailsApplicationAttributes.WEB_REQUEST,webRequest)
    RequestContextHolder.setRequestAttributes(webRequest);

    when:
    def result = service.someServiceMethod()

    then:
    result != null
    //some more assertions
    //..
  }
}

我遇到了以下错误。

| Failure:  test someServiceMethod(SomeServiceSpec)
|  org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'org.codehaus.groovy.grails.plugins.testing.GrailsMockMultipartFile@6ae8e5dd' with class 'org.codehaus.groovy.grails.plugins.testing.GrailsMockMultipartFile' to class 'org.springframework.web.multipart.commons.CommonsMultipartFile'

在grails单元测试之前有人遇到过这样的问题吗？

Answer 1

而不是：GrailsMockMultipartFile，

使用：org.springframework.mock.web.MockMultipartFile。

Answer 2

我刚刚意识到如果我们直接使用输入流就不需要以下行就不应该是问题因此解决了我的问题..

CommonsMultipartFile file = (CommonsMultipartFile) mpr.getFile("file")

grails spock test mock CommonsMultipartFile
