file - 编写Junit测试用例文件上传控制器

问题描述

我正在为文件上传控制器编写测试用例。我需要在 URL 中传递值。我需要一些帮助。

@Test
public void testHandleFileUpload() throws Exception {

    //String fileType = "Seller";
    InputStream uploadStream = PALFileUploadController.class.getClassLoader().getResourceAsStream("");
    MockMultipartFile file = new MockMultipartFile("file", uploadStream);
    assert uploadStream != null;

    this.mockMvc.perform(( fileUpload("/uploadFile/{fileType}"))
            .file(file))
            .andExpect(status().isOk());
}

我在运行此代码时看到的错误消息是

但我知道我需要将值作为“卖方”或“批准人”传递给 fileType。

请告诉我如何将值传递给 fileType 变量。提前致谢。

解决方案

没有看到您的控制器代码，很难回答，但我假设您的控制器看起来像：

@RequestMapping(value = "/uploadFile/{fileType}", method = RequestMethod.POST)
public void fileUpload(@RequestParam MultipartFile file, @PathVariable String fileType) {
    // ...
}

你的测试应该是这样的：

mockMvc.perform(MockMvcRequestBuilders.fileUpload("/uploadFile")
    .file(file)
    .param("fileType", "Seller")
    .andExpect(status().isOk());
