App Interface Automation test java+testng (iii) HTTP interface Test Example

Reproduced from: http://www.cnblogs.com/findyou/p/5388853.html description, this article for the study reference, will be deleted after a period of time. Objective
After the first two basic knowledge, this article mainly explains the National Weather Control Interface Automation test (GET request and result assertion), in order to achieve the goal of automated testing, in addition to some of the first two of the understanding, need to have a certain Java knowledge (HTTP-related).

The following examples are written again for this summary, such as reprint also please retain the source and author name findyou, thank you!

3.1.1 Description of the interface to be tested

1. National Weather Forecast Interface Example: Beijing weather

1. Address of the interface: http://www.weather.com.cn/data/cityinfo/101010100.html
2. Request Method: GET
3. Request Result:

{
"Weatherinfo": {
"City": "Beijing",
"Cityid": "101010100",
"Temp1": "15 ℃",
"Temp2": "5 ℃",
"Weather": "Cloudy",
"IMG1": "D1.gif",
"Img2": "N1.gif",
"Ptime": "08:00"
}
}

2. Test target

Request the corresponding Cityid code, whether the returned city is the expected city.

3.1.2 New Java Project

3.1.3 Writing test Cases

1. Test cases (common "two" general wording) 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= "Shenzhen";
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 ("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 Getshanghai_succ () throws ioexception{
Exp_city= "Shanghai";
Citycode= "101020100";
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);
}
}

2. Simplified Use cases

How the return value format is fixed with the request format, 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= "Shenzhen";
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": Get "+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);
}
}
