APP接口自动化测试JAVA+TestNG小实例

APP接口自动化测试JAVA+TestNG(三)之HTTP接口测试实例


以下实例均为本次总结再次编写,,如转载还请保留出处与作者姓名Findyou,谢谢!


3.1.1 待测接口说明

    1.国家气象局天气预报接口
    例:北京市天气

        接口的址:http://www.weather.com.cn/data/cityinfo/101010100.html
        请求方式:GET
        请求结果:

    复制代码
    {
        "weatherinfo": {
            "city": "北京",
            "cityid": "101010100",
            "temp1": "15℃",
            "temp2": "5℃",
            "weather": "多云",
            "img1": "d1.gif",
            "img2": "n1.gif",
            "ptime": "08:00"
        }
    }


    2.测试目标

    请求对应cityid代码,返回的城市是否是预期城市。

 

 
3.1.2 新建JAVA工程


    步骤同上一篇2.2.2.1新建JAVA工程,不再复述,如不懂请百度Eclipse新建工程

     
     1.工程结构说明

     2.Common.java源码
    复制代码
    package findyou.Interface;
    import org.codehaus.jettison.json.JSONException;
    import org.codehaus.jettison.json.JSONObject;
    public class Common {
        /**
         * 解析Json内容
         *
         * @author Findyou
         * @version 1.0 2015/3/23
         * @return JsonValue 返回JsonString中JsonId对应的Value
         **/
        public static String getJsonValue(String JsonString, String JsonId) {
            String JsonValue = "";
            if (JsonString == null || JsonString.trim().length() < 1) {
                return null;
            }
            try {
                JSONObject obj1 = new JSONObject(JsonString);
                JsonValue = (String) obj1.getString(JsonId);
            } catch (JSONException e) {
                e.printStackTrace();
            }
            return JsonValue;
        }
    }
    复制代码

     

     
     3.getCityWeathe.java源码
    复制代码
    package findyou.Interface;
    import java.io.BufferedReader;
    import java.io.DataOutputStream;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.net.HttpURLConnection;
    public class getCityWeather {
        private String url="";
        
        public String geturl() {
            return url;
        }

        public String getHttpRespone(String cityCode) throws IOException {
            String line = "";
            String httpResults = "";
            url=("http://www.weather.com.cn/data/cityinfo/"
                    + cityCode + ".html");
            try {
                HttpURLConnection connection = URLConnection
                        .getConnection(url);
                DataOutputStream out = null;
                // 建立实际的连接
                connection.connect();
                //out = new DataOutputStream(connection.getOutputStream());
                //out.flush();
                //out.close();
                BufferedReader reader = new BufferedReader(new InputStreamReader(
                        connection.getInputStream()));
                while ((line = reader.readLine()) != null) {
                    httpResults = httpResults + line.toString();
                }
                reader.close();
                // 断开连接
                connection.disconnect();
            } catch (Exception e) {
                e.printStackTrace();
            }
            return httpResults;
        }
    }
    复制代码

     

     
     4.URLConnection.java源码
    复制代码
    package findyou.Interface;
    import java.net.HttpURLConnection;
    import java.net.URL;
    public class URLConnection {    
        public static HttpURLConnection getConnection(String url){
            HttpURLConnection connection = null;
            try {
                // 打开和URL之间的连接
                URL postUrl = new URL(url);
                connection = (HttpURLConnection) postUrl.openConnection();
                 // 设置通用的请求属性
                connection.setDoOutput(true);
                connection.setDoInput(true);
                connection.setRequestMethod("GET");
                connection.setUseCaches(false);
                connection.setInstanceFollowRedirects(true);
                connection.setRequestProperty("Content-Type", "application/json");
                connection.setRequestProperty("Charset", "utf-8");
                connection.setRequestProperty("Accept-Charset", "utf-8");
            } catch (Exception e) {
                e.printStackTrace();
            }
            return connection;
        }
    }
    复制代码

     

     

 
3.1.3 编写测试用例

    1.测试用例(常见"二"一般的写法)
    复制代码
    package findyou.testcase;
    import java.io.IOException;
    import org.testng.Assert;
    import org.testng.Reporter;
    import org.testng.annotations.Test;
    import findyou.Interface.Common;
    import findyou.Interface.getCityWeather;
    public class test {
        public String httpResult= null, weatherinfo= null, city=null,exp_city = null;
        public static String cityCode="";    
        public static getCityWeather weather=new getCityWeather();

        @Test(groups = { "BaseCase"})
        public void getShenZhen_Succ() throws IOException{
            exp_city="深圳";
            cityCode="101280601";
            Reporter.log("【正常用例】:获取"+exp_city+"天气成功!");
            httpResult=weather.getHttpRespone(cityCode);
            Reporter.log("请求地址: "+weather.geturl());
            Reporter.log("返回结果: "+httpResult);
            weatherinfo=Common.getJsonValue(httpResult, "weatherinfo");
            city=Common.getJsonValue(weatherinfo, "city");
            Reporter.log("用例结果: resultCode=>expected: " + exp_city + " ,actual: "+ city);
            Assert.assertEquals(city,exp_city);
        }
        
        @Test(groups = { "BaseCase"})
        public void getBeiJing_Succ() throws IOException{
            exp_city="北京";
            cityCode="101010100";
            Reporter.log("【正常用例】:获取"+exp_city+"天气成功!");
            httpResult=weather.getHttpRespone(cityCode);
            Reporter.log("请求地址: "+weather.geturl());
            Reporter.log("返回结果: "+httpResult);
            weatherinfo=Common.getJsonValue(httpResult, "weatherinfo");
            city=Common.getJsonValue(weatherinfo, "city");
            Reporter.log("用例结果: resultCode=>expected: " + exp_city + " ,actual: "+ city);
            Assert.assertEquals(city,exp_city);
        }
        
        @Test(groups = { "BaseCase"})
        public void getShangHai_Succ() throws IOException{
            exp_city="上海";
            cityCode="101020100";
            Reporter.log("【正常用例】:获取"+exp_city+"天气成功!");
            httpResult=weather.getHttpRespone(cityCode);
            Reporter.log("请求地址: "+weather.geturl());
            Reporter.log("返回结果: "+httpResult);
            weatherinfo=Common.getJsonValue(httpResult, "weatherinfo");
            city=Common.getJsonValue(weatherinfo, "city");
            Reporter.log("用例结果: resultCode=>expected: " + exp_city + " ,actual: "+ city);
            Assert.assertEquals(city,exp_city);
        }    
    }
    复制代码

     

     
    2.简化后的用例

    如何返回值格式与请求格式固定,用例优化如下

     
    复制代码
    package findyou.testcase;
    import java.io.IOException;
    import org.testng.Assert;
    import org.testng.Reporter;
    import org.testng.annotations.Test;
    import findyou.Interface.Common;
    import findyou.Interface.getCityWeather;
    public class test {
        public String httpResult= null, weatherinfo= null, city=null,exp_city = null;
        public static String cityCode="";
        getCityWeather weather=new getCityWeather();
        
        @Test(groups = { "BaseCase"})
        public void getShenZhen_Succ() throws IOException{
            exp_city="深圳";
            cityCode="101280601";
            resultCheck(cityCode, exp_city);
        }
        
        @Test(groups = { "BaseCase"})
        public void getBeiJing_Succ() throws IOException{
            exp_city="北京";
            cityCode="101010100";
            resultCheck(cityCode, exp_city);
        }
        
        @Test(groups = { "BaseCase"})
        public void getShangHai_Succ() throws IOException{
            exp_city="上海";
            cityCode="101020100";
            resultCheck(cityCode, exp_city);
        }
        
        public void resultCheck(String cityCode_str, String exp_city_str) throws IOException{
            Reporter.log("【正常用例】:获取"+exp_city_str+"天气成功!");
            httpResult=weather.getHttpRespone(cityCode_str);
            Reporter.log("请求地址: "+weather.geturl());
            Reporter.log("返回结果: "+httpResult);
            weatherinfo=Common.getJsonValue(httpResult, "weatherinfo");
            city=Common.getJsonValue(weatherinfo, "city");
            Reporter.log("用例结果: resultCode=>expected: " + exp_city_str + " ,actual: "+ city);
            Assert.assertEquals(city,exp_city_str);        
        }
    }
