{” weatherinfo “: {” city” : “Beijing”, “cityid” : “101010100”, “temp1” : “15 ℃”, “temp2” : “5 ℃”, “weather” : “cloudy”, “img1” : “d1.gif”, “img2”: “n1.gif”, “ptime”: “08:00” } }

2. Test objectives

Request the corresponding cityID code and whether the returned city is the expected city.

2. com mon. Java source code

package findyou.Interface; import org.codehaus.jettison.json.JSONException; import org.codehaus.jettison.json.JSONObject; Public class Common {/** * Parse Json content ** @author Findyou * @version 1.0 2015/3/23 * @return JsonValue 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; }}

3. GetCityWeathe. Java source code

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 = (” www.weather.com.cn/data/cityin… + cityCode + “.html”); try { HttpURLConnection connection = URLConnection .getConnection(url); DataOutputStream out = null; // Set up the actual connection 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(); // Disconnect the connection.disconnect(); } catch (Exception e) { e.printStackTrace(); } return httpResults; }}

4. URLConnection. Java source code

package findyou.Interface; import java.net.HttpURLConnection; import java.net.URL; public class URLConnection { public static HttpURLConnection getConnection(String url){ HttpURLConnection connection = null; Try {// Open the connection to the URL URL postUrl = new URL(URL); connection = (HttpURLConnection) postUrl.openConnection(); // Set the generic request property 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; }}

1. Test cases (common “two”)

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=” sz “; cityCode=”101280601″; Reporter. Log (” [normal use case] : Get “+exp_city+” weather success!” ); httpResult=weather.getHttpRespone(cityCode); Reporter.log(” request address: “+weather.geturl()); Reporter. Log (” Return result: “+httpResult); weatherinfo=Common.getJsonValue(httpResult, “weatherinfo”); city=Common.getJsonValue(weatherinfo, “city”); Reporter. Log (” use case result: resultCode=>expected: “+ exp_city + “,actual: “+ city); Assert.assertEquals(city,exp_city); } @test (groups = {“BaseCase”}) public void getBeiJing_Succ() throws IOException{exp_city=” Beijing “; cityCode=”101010100″; Reporter.

Log (” use case result: resultCode=>expected: “+ exp_city + “,actual: “+ city); Assert.assertEquals(city,exp_city); }}

2. Simplified use cases

How to return value format and request format fixed, use case optimization as follows

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=” sz “; cityCode=”101280601”; resultCheck(cityCode, exp_city); } @test (groups = {“BaseCase”}) public void getBeiJing_Succ() throws IOException{exp_city=” Beijing “; cityCode=”101010100”; resultCheck(cityCode, exp_city); } @test (groups = {“BaseCase”}) public void getShangHai_Succ() throws IOException{exp_city=” Shanghai “; cityCode=”101020100″; resultCheck(cityCode, exp_city); } public void resultCheck(String cityCode_str, String exp_city_str) throws IOException{reporter.log (” [normal use case] : Obtain “+exp_city_str+” Weather success!” ); httpResult=weather.getHttpRespone(cityCode_str); Reporter.log(” request address: “+weather.geturl()); Reporter. Log (” Return result: “+httpResult); weatherinfo=Common.getJsonValue(httpResult, “weatherinfo”); city=Common.getJsonValue(weatherinfo, “city”); Reporter. Log (” Use case result: resultCode=>expected: “+ exp_city_str + “,actual: “+ city); Assert.assertEquals(city,exp_city_str); }}
