JMeter interface automated test read case, execute and write back result

Preface :

【 At the end of the article, a lot of benefits are prepared for you 】

One ： Environmental preparation

1. download jxl.jar This jar package

2. Once you download it , Put it in Jmeter Under the installation path of lib Under the table of contents

3.jxl.jar The role of ： Finish right Excel Read, write, and modify operations

How to use it jmter operation excel Analysis of the thinking of ：
1,Excell There are generally three most important elements ：workbook,sheet,cell
2, Want to save the results to the specified cell , Then it must be located according to these three elements .
3, First get excel File name for
4, Get form name
5, Get the coordinates of the cell
6, To get the results , Write to the corresponding cell
7, Need to use beanshell Write java Code , Get the corresponding data and write it to Excel Go inside .

Two ： Test data structure preparation

The data prepared are as follows ：（1） The test case file is named user.csv （2） The test data file is named num.csv

Be careful ： First new txt file , Then change the file extension to csv, Don't create new xls Change it to csv, Otherwise, the file cannot be read

1. Create a test case file , And import to CSV Data Set Config, Name it test_case, And set the relevant properties （ Pay attention to the circled part ）

2. Create test data file , And import to CSV Data Set Config, Name it test_data, And write a variable named tel,pwd

3、 ... and ：（1） New thread group , Create a login request http, And pass in the relevant parameters

（2） Create a new regular expression extractor , obtain http Results returned by request

Four ： Code preparation , After writing the code , export jar package , Name it CWResultFile.jar, Will export jar Put the bag in Jmeter Under the installation path directory lib--ext Under the table of contents , Then remember to restart Jmeter, Otherwise, it will not take effect

                }
    }

5、 ... and ： Add one beanshell The sampler calls the code , And use the controller only once （ Because you only need to export one Excel file ）

t=new CWOutputFile();
String filepath=t.cOutputFile(" test ");
vars.put("filepath",filepath);// To jMeter Variable , Convenient for later access .

6、 ... and ： Create another beanshell The sampler calls the code , Write data to Excel In file

s=new CWOutputFile();
String testData="{"+"\"mobilephone\":\""+"${tel}\","+"\"pwd\":\""+"${pwd}\""+"}";
String preResult=vars.get("preResult");// use get Method can ensure that the obtained string is , What is passed in is the variable name , Don't need to use ${ Variable name } This way ！
String fresult=vars.get("fresult");
s.wOutputFile("${filepath}", "${caseNo}","${testPoint}",testData,preResult,fresult);

7、 ... and ： Click on the run , stay D Find the test result file on the disk

The test result file is as follows
