java - 使用带有 Spring Boot 的 Spock 测试框架来测试我的 REST Controller

Question

情况

我有一个运行简单 REST 服务的 Spring Boot 应用程序。我想测试这项服务。由于我喜欢 Spock 框架，我很想在这里使用它，但我无法通过 Spring Configuration 解决问题。

问题

测试本身确实运行但抛出 java.net.ConnectException: Connection refused: connect异常(exception)。这里的问题是我要测试的实际应用程序没有运行 - 因此没有可用的 REST 接口(interface)。如何确保在测试运行之前实际应用程序正在运行？使用 JUnit 这个问题有点小，因为 Spring 有它的注释。但是Spock呢？

编辑:我尝试使用以下文章:http://henningpetersen.com/post/18/testing-spring-mvc-controllers-with-spock

RestHandler.java

@RestController
public class RestHandler {

  private @Autowired ExecutionService executionService;

  public RestHandler(ExecutionService executionService) {
    this.executionService = executionService;
  }

  @RequestMapping(value = "/toolbox/exec", method = POST,
          consumes = MediaType.APPLICATION_JSON_VALUE,
          produces = MediaType.TEXT_PLAIN_VALUE)
  public String executeTool(@RequestBody Tool tool) {
    executionService.execute(tool);
    return "thanks";
  }

}

ToolExecutor.java

@SpringBootApplication
public class ToolExecutor {

    public static void main(String[] args) {
        SpringApplication.run(ToolExecutor.class, args);
    }
}

RestHandlerTest.groovy

@SpringBootTest
class RestHandlerTest extends Specification {

    def someService = Mock(ExecutionService)
    def underTest = new RestHandler(someService);
    def mockMvc = MockMvcBuilders.standaloneSetup(underTest).build()

    @Shared
    def client = new RESTClient("http://localhost:603/toolbox/exec")

    def "ExecuteToolTest"() {
        when: "If POST has valid JSON format"
        Closure object = { "{\"name\":\"test\",\"parameters\":[\"abc\",\"def\"]}" }
        def response = client.request(Method.POST, object);
        then:
        with(response){
            data.text == "thanks"
            status == 200
        }

    }
}

Answer 1

这就是你需要的

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
class RestHandlerTest extends Specification {

    @Autowired
    TestRestTemplate testRestTemplate

然后你使用 testRestTemplate 而不是客户端。您还需要添加 spock-spring 依赖项。
