Converting JMeter to Load Impact: A Loading Test builder based on the Load Impact Python SDK

Introduction

This application implements the idea of building the load test configurations automatically. To fulfill its mission, it carries out several steps:

It fetches the JMX files from a drop location (assests in the root of the project), and parse the relevant fields. Right now we have only one JMX file, but the system can be easily adjusted to iterate over the drop location and parse then later. Another idea is to sort(by time, etc) and possibly delete the JMX files IF we don't need to keep them.
While parsing JMX files, it builds a python dictionary from the interested values to be used later.
Next, it builds a lua-syntax-friendly string as a string representation of user scenario.
Using the loadimpact's RESTful SDK, it sends the user scenario to their servers and gets the response back from the server.
Finally it creates a load test configuration and sends it to the server by, again, loadimpact's RESTful SDK. To test the performance of SDK, another RESTful message has been created with Requests library and has been marked as a comment in the source code.
This application has a good degree of test coverage. Test Driven Development was the the major approach while building the application.

Installing

To run the application properly, you should install two libraries :

$ pip install loadimpact
$ pip install requests

After installing the necessary libraries, clone the project into your local machine

CLI interface

A manage.py file has been built to behave as a command line interface for the application. To see the options that it provides, issue the following command:

$ python manage.py -h

As you can see there are three options : help , test and run the application

First create an API Token

Please Go to loadimpact.com account page and create an API Token. Then export the Token as an environment variable .

$ export LOADIMPACT_API_TOKEN=YOUR_API_TOKEN_GOES_HERE

Second run the tests

Let's test the application first

$ python manage.py -t test

here is a response

test_version (test_utils.TestUtilsModuleFunctions) ... ok
test_fetch_filename (test_main.TestJMXParse) ... ok
test_if_Jmetertestplan_exists (test_main.TestJMXParse) ... ok
test_if_assets_folder_exits (test_main.TestJMXParse) ... ok
test_parse_and_build_jMeter_dict (test_main.TestJMXParse) ... ok
test_build_user_scenario_string (test_main.TestUserScenarioCreator) ... ok
test_send_user_scenario_string (test_main.TestUserScenarioCreator) ... ok

----------------------------------------------------------------------
Ran 7 tests in 4.692s

OK

Third run the application

To run the application, type the following command

$ python manage.py -r run

A successful running should be

Building the load configuration test and uploading to loadimpact servers.
