我使用的是spring boot 1.3.6,我的JUNIT测试用例运行良好,在升级到spring boot 1.4.0并尝试删除不推荐的类后,我遇到了错误
我与1.3. x的JUNCLASS
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class)
@WebAppConfiguration
@IntegrationTest({"server.port=0"})
public class CustomerControllerIT {
@Value("${local.server.port}")
private int port;
private URL base;
private RestTemplate template;
@Autowired
private DataBuilder dataBuilder;
@Autowired
private CustomerRepository customerRepository;
private static final String JSON_CONTENT_TYPE = "application/json;charset=UTF-8";
@Before
public void setUp() throws Exception {
this.base = new URL("http://localhost:" + port + "/rest/customers");
template = new TestRestTemplate();
/* remove and reload test data */
customerRepository.deleteAll();
dataBuilder.createCustomers().forEach(customer -> customerRepository.save(customer));
}
@Test
public void getAllCustomers() throws Exception {
ResponseEntity<String> response = template.getForEntity(base.toString(), String.class);
assertThat(response.getStatusCode(), equalTo(HttpStatus.OK));
List<Customer> customers = convertJsonToCustomers(response.getBody());
assertThat(customers.size(), equalTo(3));
}
private List<Customer> convertJsonToCustomers(String json) throws Exception {
ObjectMapper mapper = new ObjectMapper();
return mapper.readValue(json, TypeFactory.defaultInstance().constructCollectionType(List.class, Customer.class));
}
}
我的类与1.4.0
已完成更新
更改后
@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class , webEnvironment=WebEnvironment.RANDOM_PORT)
@WebAppConfiguration
public class CustomerControllerIT {
@Value("${local.server.port}")
private int port;
private URL base;
private TestRestTemplate template;
@Autowired
private DataBuilder dataBuilder;
@Autowired
private CustomerRepository customerRepository;
private static final String JSON_CONTENT_TYPE = "application/json;charset=UTF-8";
@Before
public void setUp() throws Exception {
this.base = new URL("http://localhost:" + port + "/rest/customers");
template = new TestRestTemplate();
/* remove and reload test data */
customerRepository.deleteAll();
dataBuilder.createCustomers().forEach(customer -> customerRepository.save(customer));
}
}
现在当我尝试运行JUNIT测试用例时,我收到了NPE,如何设置随机端口以使我的JUNIT测试用例在Spring Boot 1.4.0中运行?
更新:
这是问题的症结所在

我对junit mockito非常陌生,并尝试使用mockito编写junit测试用例。 这是我的方法,我必须为此编写一个jUnit。 ChefService和ChefApi传递的方法参数来自第三方api 这里是呼叫chefService。listCookbookVersions()将返回CookBookVersion类类型的迭代器,如
我能够测试代码,但代码覆盖率不包括第二个开关情况。 请参考以下代码。 下面是我的测试代码。 由于我已经声明了一个带有测试值的字符串变量,所以我无法涵盖第二个switch语句。我尝试过if else的情况,但同样的问题发生了。我们还有别的办法吗?
我想为RESTful API Web服务编写junit测试用例,以检查DB的响应和预期响应。这里的基本流程是REST文件(调用)- 这是我的REST文件: } 这是业务逻辑文件: } 这里的问题是如何在测试用例中提供从DB for n3获取的值,因为实际代码位于不同的数据库中,我不想清理这些数据库。因此,基本上,测试用例将在不同的空数据库上运行,在运行数据库时,我必须在测试用例执行后插入数据并清理
确实给了我们单独的JVM,但是JUnit(当然)不知道单独的测试,所以报告是非常无用的。 (c)每个JUnit类一个测试: } 我们显然在这里遗漏了一些东西,因为我们的测试情况并不罕见!任何建议都非常感谢。
问题内容: 目前,我有以下 build.gradle 文件: 这 的build.gradle 文件是我的仓库 在这里 。我所有的主文件都在 src / model /中 ,它们各自的测试在 test / model中 。 如何正确添加JUnit 4 依赖项 ,然后在 测试/模型 文件夹中运行那些测试? 问题答案: 如何正确添加junit 4依赖关系? 假设您要针对标准Maven(或等效版本)存储库
我想为我的一个编写一个简单的测试,并断言输入已正确映射到: 问题:如何向该servlet发送请求正文。然后再检查一下字段是否都设置正确? 这可能与此类似,但我不知道如何检查/监视已解析的DTO? @重复标记:这不是链接问题(关于如何读取响应正文字符串)的重复。我实际上是在要求进行身体测试。
