Spring Boot+cucumber-阿里云开发者社区

简单案例

首先来看一个简单的案例

1 使用start.spring.io创建一个“web”项目。在“依赖项”对话框中搜索并添加“web”依赖项，如屏幕截图所示。点击“生成”按钮，下载zip，并将其解压缩到计算机上的文件夹中。

2 修改pom.xml

代码语言：javascript

复制

目录结构如下图

Hello.feature

代码语言：javascript

复制

Feature: Hello world
           
  Scenario: Calling a rest end point
* the application says hello

HelloController.java

代码语言：javascript

复制

package com.example.BDDSpring;
           
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@SpringBootApplication
public class Application {
    @RestController
    public static class HelloController {
        @RequestMapping("/")
        public String local() {
            return "Greetings from Local!";
        }
    }
}

HelloController.java

代码语言：javascript

复制

package com.example.BDDSpring;
           
import io.cucumber.java.en.Given;
import io.cucumber.junit.platform.engine.Cucumber;    
import io.cucumber.spring.CucumberContextConfiguration;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.web.servlet.MockMvc;
           
import static org.hamcrest.CoreMatchers.equalTo;
import static org.springframework.http.MediaType.APPLICATION_JSON;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
           
@Cucumber
@CucumberContextConfiguration    
@SpringBootTest
@AutoConfigureMockMvc
public class CucumberTest {
    @Autowired
    private MockMvc mvc;
    @Given("the application says hello")
    public void getLocalHello() throws Exception {
           mvc.perform(get("/").accept(APPLICATION_JSON))
                .andExpect(status().isOk())
                .andExpect(content().string(equalTo("Greetings from Local!")));
    }
}

用JUnit运行HelloController.java，测试成功

二一个正式的案例

1 使用start.spring.io创建一个“web”项目。在“依赖项”对话框中搜索并添加“web”依赖项，为了后面的契约文件，再加入“Config Client ”和“Contract Stub Runner依赖项。如屏幕截图所示。点击“生成”按钮，下载zip，并将其解压缩到计算机上的文件夹中。

3 目录结构如下

4 ATMService.feature

代码语言：javascript

复制

# language: zh-CN
功能:验证密码
作为银行储户
我想要在 ATM 上验证密码
以便我可以安全地进行操作
场景:查询余额
假如储户拥有一张卡号为"1111222233"的借记卡    
并且密码为"123456"
并且储户借记卡账户余额为"100.00"元
当储户将卡插入ATM
并且储户选择查询余额
那么提示储户输入密码
并且输入密码"123456"
那么储户可以看到自己的余额"100.00"元
           
场景:查询余额密码验证不通过
假如储户拥有一张卡号为"1111222233"的借记卡
并且密码为"123456"
并且储户借记卡账户余额为"100.00"元
当储户将卡插入ATM
并且储户选择查询余额
那么提示储户输入密码
并且输入密码"456987"
那么储户可以看到密码错误的提示
