Convert LoadRunner to Open-Source JMeter in Minutes

Open Source Automation
Performance Testing

As agile software development, continuous integration and continuous delivery gain traction in many organizations, the democratization of performance testing is being widely adopted. This is leading to more testing and far greater coverage. Development teams are relying less on waiting for scarce external load testing resources. Instead, they are performance testing by using open-source easy-to-use Apache JMeter™, and using it early in the development cycle. This blog will explain how to do a LoadRunner to JMeter conversion.

What is the LoadRunner to JMeter Conversion?


For a long time, HP LoadRunner was the only serious contender in the performance testing market and they could charge high annual license & maintenance fees. Besides the cost of the software itself, running large scale performance tests with LoadRunner is no easy feat.

LoadRunner’s meticulous test building and a long training process make load testing difficult. Especially compared to JMeter’s simple test building process that is easy to adopt by practitioners and advanced load testing abilities. JMeter users also enjoy extensive open-source community support as well as integration with additional open-source tools, like Jenkins for Continuous Integration, or Taurus, an open-source testing automation framework. Finally, JMeter is free, which removes licensing barriers and makes it unlimited.

Many people are looking for an open source alternative for performance testing as a result of the high price of LoadRunner. Look no more, help is here.

The free Script Converter can convert LoadRunner HTTP to JMeter and LoadRunner TruClient to Selenium in minimum time. You can also convert to Taurus and BlazeMeter. In this blog post we will explain how to convert your LoadRunner HTTP scripts to JMeter, Taurus and BlazeMeter. To learn how to convert to Selenium, click here.
