Ensuring Accurate Jenkins Pipeline Results: Failing Builds on JMeter Errors

When integrating JMeter with Jenkins, it’s crucial that your testing environment provides accurate and actionable feedback. One common challenge developers face is the situation where Jenkins shows a build as "successful" even in the presence of errors during JMeter testing. This can lead to misleading results and potentially flawed releases.

The Problem: Erroneous Success

In a typical scenario, you might run a JMeter test through a Jenkins pipeline command like this:

Encountering errors during your tests should logically lead to a failed Jenkins build. However, it’s not uncommon for the console output to indicate success, even when errors are present.

For instance, consider this output:

This can be very frustrating, especially when your testing criteria dictate that one failure should invalidate the entire process.

Existing Solutions and Their Shortcomings

JMeter Performance Plugin: While utilizing an error threshold flag for performance plugins might seem like a solution, vulnerabilities often prevent a safe implementation in production scenarios.

JSR223 Listener: Here’s a sample code that aims to fail the build if any request within a sample is unsuccessful:

However, even with this implementation, some users report Jenkins still marking the build as successful, particularly after running tests that may not be governed as expected.

The Solution: A BeanShell Listener Approach

After some exploration, it was discovered that using a BeanShell Listener effectively addresses this issue. Here’s how to implement it:

1. Add a BeanShell Listener in JMeter

Insert the following script into a BeanShell Listener:

2. Impact of the Solution

The advantage of this approach is straightforward: if there’s an error in your JMeter tests, the process will terminate immediately, prompting Jenkins to accurately fail the build. This is especially beneficial in environments where all tests need to pass for the build to be considered valid.

3. Considerations

While this method works, it's important to consider its limitations:

Incompleted Sample Execution: Unfortunately, if an error occurs, subsequent request samples will not execute. If your testing strategy doesn't allow for any failures, this is an optimal solution.

Overall Pipeline Integrity: Ensure that your build structure accounts for potential early exits, so necessary steps aren’t skipped.

Conclusion: Getting Accurate Feedback from Jenkins

In conclusion, when automating your JMeter tests in Jenkins, ensuring that builds fail appropriately in light of any errors is critical for maintaining quality in your applications. The use of a BeanShell Listener offers a reliable way to enforce this requirement.

By effectively implementing the above solution, you ensure your Jenkins builds accurately reflect the health of your JMeter tests, avoiding misleading "successful" outcomes amidst failure.



Enhancing your continuous integration process can save time, effort, and headaches down the road. So, take the necessary steps to integrate robust error handling and keep your builds clean and reliable!
