Question

我在Grails中编写了一个控制器，它接受多部分请求（xml +二进制文件1 +二进制文件2 + ...）。如何对该控制器进行单元测试？如何在单元测试中设置请求的内容？欢迎任何示例代码！

Answer 1

我使用的是Grails 2.4，您只需在单元测试中使用GrailsMockMultipartFile和request.addFile方法。

此代码适用于Grails 2.4.4，Spock测试框架：

控制器端：

class FileUploadController {

    def upload() {
        def multipartFile = request.getFile('requestParamName')
        if (multipartFile.empty) {
            flash.message = 'Error: file cannot be empty'
            render(view: 'upload')
            return
        }

        // do something now with your file
    }
}

单元测试方：

import grails.test.mixin.TestFor
import org.codehaus.groovy.grails.plugins.testing.GrailsMockMultipartFile
import spock.lang.Specification

@TestFor(FileUploadController)
class FileUploadControllerSpec extends Specification {

    void "upload should add flash error message if empty file in request"() {
        given:
        def multipartFile = new GrailsMockMultipartFile('requestParamName', 'someExcelFile.xls', 'application/vnd.ms-excel', new byte[0])
        request.addFile(multipartFile)

        when:
        controller.upload()

        then:
        assertEquals('Error: file cannot be empty', flash.message)
    }

}

Answer 2

我们正在使用Spock，我们的代码如下：

def mockFile = new MockMultipartFile(Constants.PARAM_DA_FILE, 'filename.xls', 'application/vnd.ms-
excel', articleFile.bytes)
params.(Constants.PARAM_DA_FILE) = mockFile
controller.request.addFile(mockFile)

我从http://roshandawrani.wordpress.com/2011/02/03/grails-mock-testing-a-file-upload/得到它，它正在发挥作用。以下是样本：

import org.springframework.mock.web.MockMultipartFile
import org.springframework.mock.web.MockMultipartHttpServletRequest

class FileUploadControllerTests extends grails.test.ControllerUnitTestCase
{
    void testFileUpload()

    {

        def imgContentType = 'image/jpeg'

        def imgContentBytes = '123' as byte[]
        ....
        ....

        controller.metaClass.request = new MockMultipartHttpServletRequest()
        controller.request.addFile(
        new MockMultipartFile('image', 'myImage.jpg', imgContentType, imgContentBytes)       )
        ....
        controller.save()
        assertEquals HttpServletResponse.SC_OK, controller.response.status
        ....

    }
}

使用多部分请求测试Grails控制器
