An article about motivations to create this tool: https://dzone.com/articles/convert-a-har-file-to-jmeter-script

Creating a har file and run the tool har-to-jmx-convertor to simulate recording from the JMeter recording template

This tool har-to-jmx-convertor try to simulate a script JMeter and a record xml file recording from the JMeter recording template.

JMeter recording template and HTTP(S) Test Script Recorder - The standard way to record

The JMeter recording template : <br/>

The result of recording with JMeter "HTTP(S) Test Script Recorder" : <br/>

HAR created on a Browser (e.g. Firefox) - The new way with the convertor tool

Record the navigation in the web application with Developper tool : Network and save exchanges in HAR file format : <br/>

Launch the "Convertor tool" : <br/>

Tool results : Open the script created and the record.xml in a View Results Tree <br/>

HAR created in Chrome Browser with the LoadRunner Web Recorder Chrome Extension

This tool is compatible with Har file generated with the LoadRunner Web Recorder Chrome Extension.

The main advantage is to declare Transaction Names when recording and navigate to the web site. This transactions will be Page Names (Transaction Controllers names) in the JMeter script.

The LoadRunner Web Recorder Chrome Extension is available at this url : <br/> Download the Recorder extension for Chrome : "HarGeneratorChrome"

You need to add the parameter and value : <code>-use_lrwr_infos transaction_name</code> to indicate that is a HAR file generated with LoadRunner Web Recorder (lrwr).

Standard HAR file created with Firefox, Chrome, Edge with external csv file for transaction information

You could add an external file that contains information about transaction name start and end.

The CSV format is :

• <code>Timestamp iso format GMT;TRANSACTION;transaction name;start</code> for starting a new transaction
• <code>Timestamp iso format GMT;TRANSACTION;transaction name;stop</code> for ending transaction the precedent transaction
• Separator ";"
• Charset UTF-8

E.g :

A simple tool named "create-external-file-for-har" create easily this csv file. https://github.com/vdaburon/create-external-file-for-har

You need to add the parameter and value : <code>-external_file_infos c:/Temp/jpetstore.csv</code> to set the csv file to read
