grails spock 测试模拟 CommonsMultipartFile

Question

我遵循用代码编写的旧方法，用于访问服务中的请求对象 class 例如：

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

这是我的服务单元测试代码class。

@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'

以前有人在 grails 单元测试中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，下面这行是不必要的，它应该不是问题，因此解决了我的问题..

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