Question

我正在使用Spring Test Framework测试注册表单提交。我使用param传递参数，但参数断言失败，因为值为null。以下是代码

控制器：

@RequestMapping("/signup")
public ModelAndView signUp(@ModelAttribute(value = "signupForm") @Valid SignupForm form, BindingResult bResult) {
    ModelAndView mv = new ModelAndView();
    if (bResult.hasErrors()) {
        mv.setViewName("signupform");
        return mv;
    }
    mv.setViewName("home");
    userService.sigUpUser(form);
    return mv;
}

提交的控制器测试：

@Test
public void goSignupFormSubmit() throws Exception {

    this.mockMvc.perform(post("/signup").contentType(MediaType.APPLICATION_FORM_URLENCODED)
            .param("username", "somebody@gmail.com")
            .param("password", "somebody")
            .param("firstName", "somebody")
            .param("lastName", "kumar")
            ).andDo(print())
    .andExpect(status().isOk())
    .andExpect(view().name("home"))
    .andExpect(forwardedUrl("/WEB-INF/template/default.jsp"))
    .andExpect(model().attribute("username", is("somebody@gmail.com")))
    .andExpect(model().attribute("password", is("somebody")))
    .andExpect(model().attribute("firstName", is("somebody")))
    .andExpect(model().attribute("lastName", is("kumar")));

}

测试结果：

java.lang.AssertionError: Model attribute 'username'
Expected: is "somebody@gmail.com"
 got: null

以下为我工作。下面是我的控制器的代码及其相应的控制器测试。希望能帮助到你。也不确定为什么这个问题被否决了。

控制器：

@RequestMapping("/signup")
public ModelAndView signUp(@ModelAttribute(value = "signupForm") @Valid SignupForm form, BindingResult bResult) {

    ModelAndView mv = new ModelAndView();
    if (bResult.hasErrors()) {
        mv.setViewName("signupform");
        return mv;
    }
    User user = userService.sigUpUser(form);
    mv.addObject("user", user);
    mv.setViewName("home");
    return mv;
}

检查表单提交：

@Test
public void goSignupFormSubmit() throws Exception {

    this.mockMvc
            .perform(post("/signup").contentType(MediaType.APPLICATION_FORM_URLENCODED)
                    .param("username", "somebody@gmail.com").param("password", "somebody")
                    .param("firstName", "somebody").param("lastName", "kumar"))
            .andDo(print()).andExpect(status().isOk()).andExpect(view().name("home"))
            .andExpect(forwardedUrl("/WEB-INF/template/default.jsp"))
            .andExpect(model().attribute("signupForm", hasProperty("username", is("somebody@gmail.com"))))
            .andExpect(model().attribute("signupForm", hasProperty("password", is("somebody"))))
            .andExpect(model().attribute("signupForm", hasProperty("firstName", is("somebody"))))
            .andExpect(model().attribute("signupForm", hasProperty("lastName", is("kumar"))));

}

检查数据库插入：

@Test
public void goSignupFormDatabaseInsertion() throws Exception {

    this.mockMvc
            .perform(post("/signup").contentType(MediaType.APPLICATION_FORM_URLENCODED)
                    .param("username", "somebody@gmail.com").param("password", "somebody")
                    .param("firstName", "somebody").param("lastName", "kumar"))
            .andExpect(status().isOk()).andExpect(view().name("home"))
            .andExpect(forwardedUrl("/WEB-INF/template/default.jsp"))
            .andExpect(model().attribute("user", hasProperty("username", is("somebody@gmail.com"))))
            .andExpect(model().attribute("user", hasProperty("password", is("somebody"))))
            .andExpect(model().attribute("user", hasProperty("enabled", is(1))))
            .andExpect(model().attribute("user", hasProperty("authority", hasProperty("username", is("somebody@gmail.com")))))
            .andExpect(model().attribute("user", hasProperty("authority", hasProperty("authorityType", is("candidate")))))
            .andExpect(model().attribute("user", hasProperty("userDetails", hasProperty("username", is("somebody@gmail.com")))))
            .andExpect(model().attribute("user", hasProperty("userDetails", hasProperty("firstName", is("somebody")))))
            .andExpect(model().attribute("user", hasProperty("userDetails", hasProperty("lastName", is("kumar")))));

}

在Spring Test Framework Controller测试中获取表单参数的null
