Spock & Spring Boot 集成测试

Question

我有一个 Spring Boot 1.5.1.RELEASE 项目，使用 Spock 1.1 进行集成测试。我有一个基本控制器：

\n\n

@RestController("/words")\npublic class WordsController {\n\n   @RequestMapping(method = RequestMethod.GET)\n   @ResponseBody\n   public ResponseEntity getAllWords() {\n      return ResponseEntity\n         .status(HttpStatus.OK)\n         .contentType(MediaType.APPLICATION_JSON)\n         .body("Your list of words go here");\n   }\n}\n

\n\n

我正在尝试使用以下方法测试端点：

\n\n

@ContextConfiguration(classes = MyApplication.class)\n@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)\n@ActiveProfiles("test")\nclass WordsControllerTest extends Specification {\nRESTClient restClient = new RESTClient("http://localhost:3000", ContentType.JSON)\n\n    def "test the GET endpoint is available"() {\n        when:\n        def response = restClient.get(\n                path: \'/words\',\n                requestContentType: JSON\n        )\n\n        then:\n        response.status == 200\n    }\n

\n\n

这是我的应用程序主类：

\n\n

@SpringBootApplication\npublic class MyApplication {\n\n    public static void main(String[] args) {\n        SpringApplication.run(MyApplication.class, args);\n    }\n\n}\n

\n\n

但是当我运行这个时，我收到一个非常奇怪的错误：

\n\n

\n

groovyx.net.http.RESTClient：解析\n \'application/json\' 响应时出错

\n\n

groovy.json.JsonException: 无法确定当前字符，\n 它不是字符串、数字、数组或对象

不确定它是否有什么不同，但这是我的 gradle 文件的一部分：

\n\n

compile(\'org.springframework.boot:spring-boot-starter-data-jpa\')\ncompile(\'org.springframework.boot:spring-boot-devtools\')\ncompile("org.springframework.boot:spring-boot-starter-web:${springBootVersion}")\nruntime(\'com.h2database:h2\')\ncompile group: \'org.codehaus.groovy.modules.http-builder\', name: \'http-builder\', version: \'0.7.1\'\ntestCompile(\'org.springframework.boot:spring-boot-starter-test\')\ntestCompile(\'org.spockframework:spock-core:1.1-groovy-2.4-rc-2\')\ntestCompile(\'org.spockframework:spock-spring:1.1-groovy-2.4-rc-2\')\ntestCompile "org.hamcrest:hamcrest-core:1.2"\n

我不确定为什么 JSON 没有正确发送或接收。

Answer 1

将端点标记为返回媒体类型是不够的application/json。您还需要返回有效的JSON 内容，其中：

"Your list of words go here"

不是。

如果需要返回列表，请写入：

return ResponseEntity
   .status(HttpStatus.OK)
   .contentType(MediaType.APPLICATION_JSON)
   .body("{\"words\": [\"one\", \"two\"]}");

或一条简单的消息：

return ResponseEntity
   .status(HttpStatus.OK)
   .contentType(MediaType.APPLICATION_JSON)
   .body("{\"msg\": \"content\"");

Spring可以自动将POJO映射到JSON负载，看看@ResponseBody
