如何测试SpringBoot的请求?使用spring-boot-starter-test这个包即可完成测试，SpringBoot项目为什么需要测试的意义大猪就不跟小伙伴们多聊了哈，重点放在测试代码上，我们直接开撸。

使用说明

导包gradle项目

compile group: 'com.fasterxml.jackson.jaxrs', name:'jackson-jaxrs-xml-provider',version:'2.5.0'
compile group: 'org.springframework.boot', name: 'spring-boot-starter-test', version: '1.5.3.RELEASE'

导包maven项目

<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-test -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <version>1.5.3.RELEASE</version>
    <scope>test</scope>
</dependency>

还需要依赖junit包，大家自行导入

关键核心测试例子

@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@EnableAutoConfiguration
public class BBTestAA {
    @Autowired
    private TestRestTemplate testRestTemplate;

    //Application.class 为SpringBoot的启动入口类,每个SpringBoot项目大家都会配置
}

GET请求测试

    @Test
    public void get() throws Exception {
        Map<String,String> multiValueMap = new HashMap<>();
        multiValueMap.put("username","lake");//传值，但要在url上配置相应的参数
        ActResult result = testRestTemplate.getForObject("/test/get?username={username}",ActResult.class,multiValueMap);
        Assert.assertEquals(result.getCode(),0);
    }

POST请求测试

    @Test
    public void post() throws Exception {
        MultiValueMap multiValueMap = new LinkedMultiValueMap();
        multiValueMap.add("username","lake");
        ActResult result = testRestTemplate.postForObject("/test/post",multiValueMap,ActResult.class);
        Assert.assertEquals(result.getCode(),0);
    }

文件上传测试

    @Test
    public void upload() throws Exception {
        Resource resource = new FileSystemResource("/home/lake/github/wopi/build.gradle");
        MultiValueMap multiValueMap = new LinkedMultiValueMap();
        multiValueMap.add("username","lake");
        multiValueMap.add("files",resource);
        ActResult result = testRestTemplate.postForObject("/test/upload",multiValueMap,ActResult.class);
        Assert.assertEquals(result.getCode(),0);
    }

文件下载测试

    @Test
    public void download() throws Exception {
        HttpHeaders headers = new HttpHeaders();
        headers.set("token","xxxxxx");
        HttpEntity formEntity = new HttpEntity(headers);
        String[] urlVariables = new String[]{"admin"};
        ResponseEntity<byte[]> response = testRestTemplate.exchange("/test/download?username={1}",HttpMethod.GET,formEntity,byte[].class,urlVariables);
        if (response.getStatusCode() == HttpStatus.OK) {
            Files.write(response.getBody(),new File("/home/lake/github/file/test.gradle"));
        }
    }

请求头信息传输测试

    @Test
    public void getHeader() throws Exception {
        HttpHeaders headers = new HttpHeaders();
        headers.set("token","xxxxxx");
        HttpEntity formEntity = new HttpEntity(headers);
        String[] urlVariables = new String[]{"admin"};
        ResponseEntity<ActResult> result = testRestTemplate.exchange("/test/getHeader?username={username}", HttpMethod.GET,formEntity,ActResult.class,urlVariables);
        Assert.assertEquals(result.getBody().getCode(),0);
    }

PUT

    @Test
    public void putHeader() throws Exception {
        HttpHeaders headers = new HttpHeaders();
        headers.set("token","xxxxxx");
        MultiValueMap multiValueMap = new LinkedMultiValueMap();
        multiValueMap.add("username","lake");
        HttpEntity formEntity = new HttpEntity(multiValueMap,headers);
        ResponseEntity<ActResult> result = testRestTemplate.exchange("/test/putHeader", HttpMethod.PUT,formEntity,ActResult.class);
        Assert.assertEquals(result.getBody().getCode(),0);
    }

DELETE

    @Test
    public void delete() throws Exception {
        HttpHeaders headers = new HttpHeaders();
        headers.set("token","xxxxx");
        MultiValueMap multiValueMap = new LinkedMultiValueMap();
        multiValueMap.add("username","lake");
        HttpEntity formEntity = new HttpEntity(multiValueMap,headers);
        String[] urlVariables = new String[]{"admin"};
        ResponseEntity<ActResult> result = testRestTemplate.exchange("/test/delete?username={username}", HttpMethod.DELETE,formEntity,ActResult.class,urlVariables);
        Assert.assertEquals(result.getBody().getCode(),0);
    }
