Using ChatGPT to Create BlazeMeter Performance Test Scripts

Many times, you find there are situations where people need to get their testing up and running quickly. In the case of performance testing, creating scripts quickly and simply is especially critical for teams to provide seamless experiences for their customers. 

For those testers in an especially quick pinch, ChatGPT can be particularly useful. While ChatGPT has made headlines recently due to its ease of use and advanced AI capabilities when it comes to content creation, it can also be useful in other areas. This blog will explore how ChatGPT can be helpful when it comes to performance testing, and show how to generate performance-testing scripts with ChatGPT that you can then run on the BlazeMeter platform. 

How Does ChatGPT Help With Performance Testing?

ChatGPT, an AI language model developed by OpenAI, can be used to create performance-testing scripts for use on the BlazeMeter platform. Software performance testing is an essential part of development that helps ensure that an application can handle the expected load and provide a high level of performance for users. 

BlazeMeter is a popular cloud-based platform for performance testing, providing a suite of tools for creating, executing, and analyzing performance tests. Using ChatGPT, developers can quickly and easily create performance testing scripts in the desired language format, such as Taurus, JMeter, or Gatling, as well as several other frameworks and languages. 

ChatGPT can be integrated with BlazeMeter in several ways. Developers can use the ChatGPT API to programmatically create performance testing scripts, which can then be imported into BlazeMeter. Alternatively, developers can interact with ChatGPT through its natural language interface, which provides a simple and intuitive way to create performance testing scripts. 

Why Use ChatGPT for Performance Testing?

Using ChatGPT to create performance testing scripts for the BlazeMeter platform provides several benefits:

• It saves time and reduces the complexity of the script creation process, making it easier for developers to focus on other important aspects of the testing process. 
• With the ability to generate scripts in a variety of formats, ChatGPT provides a flexible and scalable solution for performance testing on the BlazeMeter platform. 
• ChatGPT can be very useful for testers starting to use the system and lowering the learning curve.

ChatGPT Performance Test Creation Example

For this demo of creating a performance test script with ChatGPT, I’m going to create a script in Taurus. Taurus is a domain-specific language (DSL) for defining scripts using a YAML formatted configuration file. In the YAML file, you specify the type of script to execute, how many concurrent users, and what end-point to test. Obviously, you can set many other configuration settings as well. So given the recent hype on AI and the ChatGPT, we were wondering if it could be used for creating testing scripts to run on BlazeMeter. 

To create a performance testing script with ChatGPT, developers simply need to provide the necessary information such as the target URL, the number of virtual users, the ramp-up time, and the duration of the test. I entered the following query into ChatGPT:

Write a Taurus YAML file to run a performance test on https://demoblaze.com for 10 virtual users, for 5 minutes, and with a ramp up time of 1 minute.

ChatGPT generated the following performance testing script in Taurus to be imported into BlazeMeter. 

execution:
 - concurrency: 10
   ramp-up: 1m
   hold-for: 5m
   scenario: simple-scenario
scenarios:
 simple-scenario:
  requests:
   - url: https://demoblaze.com
modules:
 reporting:
  - module: console

Once you have the generated script, you can save it into a file locally. For this example, I am referring to the script as script.yaml. Then, you can upload the script to BlazeMeter using our user-friendly interface. 

Creating a test in BlazeMeter is easy. Just click on the Create Test button and then on the big Plus icon to add the script file.

Once the script has been imported into BlazeMeter, developers can use the platform’s suite of tools to execute the test and analyze the results. BlazeMeter provides real-time performance monitoring, detailed reports, and graphs, which can be used to identify performance bottlenecks and make improvements.

ChatGPT and JMeter Testing

The above example shows how ChatGPT could quickly aid a tester in creating a Taurus test and running it in BlazeMeter. However, I tried doing the same with JMeter, and here I ran into some problems. 

If you ask ChatGPT to create a JMeter test, it will use version 1.0 of JMeter, which is not up-to-date. Also, it may not create a complete JMX file because of size limitations. Generally speaking, keep in mind that ChatGPT is based on data scanned in 2021 and may not be familiar with the latest versions of any language.

Bottom Line

If you are looking to speed up your performance test script creation, ChatGPT is certainly an interesting avenue to explore. The Taurus script generated by ChatGPT in this blog works great and is syntactically correct, which is really quite remarkable. Yet it is important to note that I gave a simple example and did not try more complex test scenarios with different languages as executors. 

But for automatically running the tests themselves, you don’t need ChatGPT. You have BlazeMeter. See how simple it is to execute your performance tests at scale with BlazeMeter’s testing platform today.
