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

Sheet.addCell(labe30); Sheet.addCell(labe40); Sheet.addCell(labe50); Sheet.addCell(labe60); Sheet.addCell(labe70); writeBook.write(); writeBook.close(); } return filepath; } }
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
