Creating DevOps JMeter CI/CD pipeline Using Taurus

About JMeter

Apache JMeter is a highly versatile open-source integration testing tool. It is often used as a load testing tool for web applications, but can also be used for functional testing and for testing other types of services, such as databases.

About Taurus

Taurus is an open-source automation test framework, that can be used in particular to automate JMeter executions. Taurus can take an existing JMeter plan and define load profile and assertions through simple configuration. Taurus can export a test report in JUnit format, that can be published to an Azure DevOps pipeline.

About the JMeter extension

This extension provides the following components:

• A JMeterInstaller task that installs JMeter along with a flexible collection of plugins
• A TaurusInstaller task that installs Taurus on a Python 3.6+ environment
• A TaurusRunner task that can run JMeter or other test plans using Taurus and produces test results and reports

The JMeter tool installer task acquires a specified version of JMeter from the Internet or the tools cache and prepends it to the PATH of the Azure Pipelines Agent (hosted or private). This task can be used to change the version of JMeter used in subsequent tasks. Adding this task before the TaurusRunner in a build definition ensures you are using that task with the right JMeter version.

This extension is intended to run on Windows, Linux and MacOS agents.
