虽然我写了这文章，但是我不建议这种做法，原因很简单，这是把简单事情复杂化。

什么是Cucumber？什么是BDD？这里不细讲，不懂的直接查看官方：https://cucumber.io/
　　什么是Rest Assured？传送门：https://github.com/rest-assured/rest-assured

以下以java为开发语言，快速搭建一个cucumber+Rest Assured的api自动化测试平台。
　　1. 用IDEA 新建一个Maven工程，并pom文件添加如下配置：

     
        <!--ccucumber 相关依赖-->
        <dependency>
            <groupId>info.cukes</groupId>
            <artifactId>cucumber-java8</artifactId>
            <version>1.2.4</version>
            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>info.cukes</groupId>
            <artifactId>cucumber-java</artifactId>
            <version>1.2.4</version>
        </dependency>

        <!-- https://mvnrepository.com/artifact/info.cukes/cucumber-html -->
        <dependency>
            <groupId>info.cukes</groupId>
            <artifactId>cucumber-html</artifactId>
            <version>0.2.3</version>
        </dependency>

        <!--rest-assured 接口测试框架-->
        <!-- https://mvnrepository.com/artifact/com.jayway.restassured/rest-assured -->
        <dependency>
            <groupId>com.jayway.restassured</groupId>
            <artifactId>rest-assured</artifactId>
            <version>2.9.0</version>
        </dependency>

        <!-- https://mvnrepository.com/artifact/org.testng/testng -->
        <dependency>
            <groupId>org.testng</groupId>
            <artifactId>testng</artifactId>
            <version>6.9.10</version>
        </dependency>

        <!--log 引入-->
        <dependency>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
            <version>1.2.17</version>
        </dependency>

        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
            <version>1.7.5</version>
            <scope>provided</scope>
        </dependency>

        <!--compare jsoon-->
        <dependency>
            <groupId>net.javacrumbs.json-unit</groupId>
            <artifactId>json-unit</artifactId>
            <version>1.13.0</version>
        </dependency>

        <!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind -->
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>2.8.1</version>
        </dependency>

2. 新建个ApiTools类，并对Rest Assured进程二次封装，主要是Post 和 Get请求的基础封装和对返回json解析的封装，具体代码如下：

  /**
     * 带json的post请求
     *
     * @param apiPath api地址
     * @param json    请求json
     * @return api返回的Response
     */
    public static Response post(String apiPath, String json) {
//        开始发起post 请求
        String path = Parameters.BOSEHOST + apiPath;
        Response response = given().
                contentType("application/json;charset=UTF-8").
                headers("header1", "value1").
                cookies("cookies1", "value1").
                body(json).
                when().log().all().post(path.trim());
        log.info(response.statusCode());
        log.info("reponse:");
        response.getBody().prettyPrint();
        return response;
    }

    /**
     * get 请求
     *
     * @param apiPath api路径
     * @return api的response
     */
    public static Response get(String apiPath) {
//        开始发起GET 请求
        String path = Parameters.BOSEHOST + apiPath;
        Response response = given().
                contentType("application/json;charset=UTF-8").
                headers("headers1", "value1").
                cookie("cookie1", "value1").
                when().log().all().get(path.trim());
        log.info(response.statusCode());
        log.info("reponse:");
        response.getBody().prettyPrint();
        return response;
    }

    /**
     * 获取json中某个key值
     * @param response  接口返回
     * @param jsonPath  jsonpath, 例如 a.b.c   a.b[1].c  a
     * @return
     */
    public static String getJsonPathValue(Response response, String jsonPath) {
        String reponseJson = String.valueOf(response.jsonPath().get(jsonPath));
//        String jsonValue = String.valueOf(from(reponseJson).get(jsonPath));
        return reponseJson;
    }

3.新建个Steps 类，完成常用step的封装，具体代码如下：

import com.jayway.restassured.response.Response;
import com.tools.apitools.ApiTools;
import com.tools.apitools.MyAssert;
import com.tools.filetools.ReadTxtFile;
import cucumber.api.java.en.Then;
import cucumber.api.java.en.When;
import static net.javacrumbs.jsonunit.JsonAssert.assertJsonEquals;
/**
 * Created by MeYoung on 8/1/2016.
 * <p>
 * Steps 集合
 */
public class Steps {

    Response response = null;

    @When("^I send a GET request to \"(.*?)\"$")
    public void getRequest(String path) {
        response = ApiTools.get(path);
    }

    @When("^I send a POST request to \"(.*?)\"$")
    public void postRequest(String apiPath) throws Throwable {
        response = ApiTools.post(apiPath);
    }

    @When("^I send a POST request to \"(.*?)\" and request json:$")
    public void postRequestWithJson(String apiPath, String json) {
        response = ApiTools.post(apiPath, json);
    }

    @When("^I use a \"(.*?)\" file to send a POST request to \"(.*?)\"$")
    public void postRequestWihtFile(String fileName, String path) {
        String json = ReadTxtFile.readTxtFile(fileName);
        response = ApiTools.post(path, json);
    }

    @Then("^the JSON response equals$")
    public void assertResponseJson(String expected) {
        String responseJson = response.body().asString();
        assertJsonEquals(responseJson, expected);
    }

    @Then("^the JSON response equals json file \"(.*?)\"$")
    public void theJSONResponseEqualsJsonFile(String fileName) {
        String responseJson = response.body().asString();
        String fileJson = ReadTxtFile.readTxtFile(fileName);
        assertJsonEquals(responseJson, fileJson);
    }

    @Then("^the response status should be \"(\\d{3})\"$")
    public void assertStatusCode(int statusCode) {
        Object jsonResponse = response.getStatusCode();
        MyAssert.assertEquals(jsonResponse, statusCode);
    }

    @Then("^the JSON response \"(.*?)\" equals \"(.*?)\"$")
    public void assertEquals(String str, String expected) {
        String jsonValue = ApiTools.getJsonPathValue(response, str);
        MyAssert.assertEquals(jsonValue, expected);
    }

    @Then("^the JSON response \"(.*?)\" type should be \"(.*?)\"$")
    public void assertMatch(String str, String match) {
        String jsonValue = ApiTools.getJsonPathValue(response, str);
        MyAssert.assertMatch(jsonValue, match);
    }

    @Then("^the JSON response \"(.*?)\" should be not null$")
    public void assertNotNull(String str) {
        String jsonValue = ApiTools.getJsonPathValue(response, str);
        MyAssert.assertNotNull(jsonValue);
    }

    @Then("^the JSON response \"(.*?)\" start with \"(.*?)\"$")
    public void assertStartWith(String str, String start) {
        String jsonValue = ApiTools.getJsonPathValue(response, str);
        MyAssert.assertStartWith(jsonValue, start);
    }
    @Then("^the JSON response \"(.*?)\" end with \"(.*?)\"$")
    public void assertEndWith(String str, String end) {
        String jsonValue = ApiTools.getJsonPathValue(response, str);
        MyAssert.assertEndWith(jsonValue, end);
    }
    @Then("^the JSON response \"(.*?)\" include \"(.*?)\"$")
    public void assertInclude(String str, String include) {
        String jsonValue = ApiTools.getJsonPathValue(response, str);
        MyAssert.assertInclude(jsonValue, include);
    }
}

当然上面代码还涉及到一些Asssert的封装，这里就不列出来，个人喜好不同，更具自己熟悉的情况去引入自己熟悉的jar包。

ok，最后我们愉快的写两个case，看看效果：

  @get
  Scenario Outline: use examples
    When I send a GET request to "apiurl"
    Then the response status should be "200"
    Then the JSON response "<jsonPath>" equals "<value>"
    Examples:
      | jsonPath     | value             |
      | genericPlan  | false             |
      | ehiCarrierId | 90121100          |
      | carrierName  | Anthem Blue Cross |

  @post
  Scenario: test post request
    When I send a POST request to "apiurl"
    Then the response status should be "200"
    And the JSON response "message" equals "success"
    #    校验放回值是否是某种类型
    And the JSON response "sessionId" type should be "^\d{6}$"
    #    校验返回值不为空
    And the JSON response "url" should be not null
    #    校验是否以XX开头
    Then the JSON response "message" start with "su"
    #    校验是否以XX开头
    Then the JSON response "message" end with "ss"
    #    校验是否以XX开头
    Then the JSON response "message" include "ss"
    #    校验返回json是否为XXX，对整个返回json的校验
    Then the JSON response equals
    """
      {
          "result":"success"
      }
    """

通过Junit 运行feature.

1. 在Pom.xml 文件添加junit相关包：

        <dependency>
            <groupId>info.cukes</groupId>
            <artifactId>cucumber-junit</artifactId>
            <version>1.2.4</version>
            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
            <scope>test</scope>
        </dependency>

2. 在feature 同级目录下新建个运行类，代码例子如下：

import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;
import org.junit.runner.RunWith;

@RunWith(Cucumber.class)
@CucumberOptions(
        strict = true,
        monochrome = true,
        plugin = {"pretty", "html:target/cucumber", "json:target/cucumber.json"},
        features = {"src/test/java/bosev2"},
        glue = {"com.bose.step"},
        tags = {"~@unimplemented"})
public class RunnerBoseTest {
}

@RunWith(Cucumber.class) ： 注解表示通过Cucumber的Junit 方式运行脚本
@CucumberOptions () ：注解用于配置运行信息，其中代码中的plugin 表示测试报告输出的路径和格式， feature 表示被运行的feature文件的包路径， glue中配置steps的包路径地址，tags中配置要运行的用例的tags名，其实~符号表示除了这个tags的所有tags.

通过Jenkins 执行

1. 在Pom.xml 文件里面添加运行插件，如下：

 <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.3</version>
                <inherited>true</inherited>
                <configuration>
                    <source>1.7</source>
                    <target>1.7</target>
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.18.1</version>
                <configuration>
                    <reuseForks>false</reuseForks>
                </configuration>
            </plugin>
        </plugins>
    </build>

2. 在Jenkins 中添加Cucumber-JVM reports插件。
3. 新建Maven job，配置maven构建方式和构建后的测试报告展示。

Cucumber-JVM reports 提供了非常漂亮的report，如下：
