A Guide to JMeter Preprocessors and Postprocessors

When building your JMeter test, samplers provide the core functionality. They are responsible for sending the actual HTTP requests and handling those responses. However, as your test becomes more complex and sophisticated, it may be desirable to add conditional logic to your requests. Furthermore, you may wish to dynamically process the inputs and outputs to these. JMeter provides this functionality though a host of preprocessors and postprocessors. This brief post will serve as a guide toRead More →

JMeter Timers Primer

Some of the most versatile components in JMeter are timers. Without JMeter timers, elements of a JMeter test plan are executed sequentially without pausing. This can potentially overwhelm your target test application by generating too many requests in a short period of time. In this brief post, we will cover most of the available types of timers that can be used in JMeter test plans. You can find all available timer elements under the “Timers” submenuRead More →

Schedule a load test

Once some users have written their load tests, they want to schedule a load test to run at a particular time or as part of a continuous integration build process. Or even run a recurring test at the same time on a schedule.  The RedLine13 API makes this all possible. A Practical Example In a previous post we showed how to get started using the RedLine13 API. Building upon this, you can use your scripting languageRead More →

Extracting Metadata from Load Generator Instances

RedLine13 load generator instances are backed by AWS EC2 instances. AWS exposes a special locally-addressable endpoint that returns metadata about that instance. Using this, you can ascertain such things as the region in which your instance resides, private and public addresses, and instance tags amongst other useful data points. A specific example of where this would be useful is where you have defined a load test to run in multiple regions, with a number of EC2-backedRead More →

Pitfalls of Selenium Load Testing

Tests created with Selenium WebDriver replicate the user experience from the perspective of the UI.  It can be thought of as a top-down approach whereby it accurately replicates the behavior of an end user. Running through a browser instance such as Chrome or Firefox, the test process itself interacts with the actual user interface elements of a target test application. This is in contrast to many other testing frameworks.  One of the most popular is JMeter,Read More →
