Question

我尝试使用带有Thymeleaf的Spring 4构建一些基本的Web应用程序，我遇到了测试问题。

首先是我的build.gradle依赖项：

dependencies {
    compile("org.springframework:spring-webmvc:4.0.5.RELEASE")
    compile("org.thymeleaf:thymeleaf-spring4:2.1.3.RELEASE")
    compile 'org.springframework:spring-test:4.0.5.RELEASE'
    providedCompile("javax:javaee-web-api:6.0")
    testCompile("junit:junit")
    testCompile ("org.mockito:mockito-all:1.9.5")
}

接下来，我的控制器类：

package pl.com.tegess.RetrospectionSystem;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;

@Controller
public class GreetingController {

@RequestMapping("/greeting")
public String greeting(@RequestParam(value="name", required=false, defaultValue="World") String name, Model model) {
    model.addAttribute("name", name);
    return "greeting";

}

}

和测试：包pl.com.tegess.RetrospectionSystem;

import org.junit.Before;
import org.junit.Test;
import org.mockito.InjectMocks;
import org.mockito.MockitoAnnotations;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import pl.com.tegess.RetrospectionSystem.configuration.WebAppConfiguration;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.forwardedUrl;
import static org.springframework.test.web.servlet.setup.MockMvcBuilders.standaloneSetup;

public class GreetingControllerTest {

private static final String greetingView = "/WEB-INF/templates/greeting.html";


MockMvc mockMvc;

@InjectMocks
GreetingController controller;

@Before
public void setup(){
    MockitoAnnotations.initMocks(this);
    mockMvc = standaloneSetup(controller).setViewResolvers(viewResolver()).build();
}

private InternalResourceViewResolver viewResolver() {
    InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
    viewResolver.setPrefix("/WEB-INF/templates/");
    viewResolver.setSuffix(".html");
    return viewResolver;
}

@Test
public void testGreeting() throws Exception {
    mockMvc.perform(get("/greeting")).andExpect(forwardedUrl(greetingView));
}
}

当我进行这项测试时，我得到的是：

你有什么想法吗？

Answer 1

需要添加一些测试范围依赖项，这将有助于您进行开发和测试

testCompile 'javax.el:javax.el-api:3.0.0'   
testCompile 'org.glassfish.web:el-impl:2.2'
providedCompile 'javax.servlet:javax.servlet-api:3.0.1'

你可以摆脱

providedCompile("javax:javaee-web-api:6.0")

因为它下载了很多依赖项，这些依赖项有助于开发时间而不是测试时间
