Simulate Slow Internet Connections with JMeter

When we think of performance testing, often the first thing that comes to mind are highly scaled systems generating as much traffic as possible. This is done because we consider the most extreme conditions a production environment will encounter is when many users (or a coordinated attack) converge at once. However, extreme conditions can also be encountered at the other end of the spectrum with poor quality network connections. For example, a RedLine13 customer discovered thatRead More →

Performance test video streaming services

RedLine13 Technology Partner UBIK has published a case study using UbikLoadPack and RedLine13 to performance test video streaming services. Their client wanted to verify that his infrastructure could properly handle the delivery of a live sporting event with up to 150,000 watchers. The test needed to verify the following: Test Objectives Customers user experience (no lags, accuracy of stream, no delay) CDN and Origin delivery performance Bandwidth of the network Load balancing across 2 Data centersRead More →

rerun a test

Have you ever had the need to run the same test more than once?  Or perhaps you’ve needed to run a similar test that only needed to be changed slightly. In these cases, it can be tedious and time consuming to re-enter all of the testing parameters and environment setup.  However, RedLine13 premium subscribers can duplicate any test with a single click! When you click on the “Clone” button, a copy of your test is created.Read More →

Distribute your JMeter clients across different regions with RedLine13

This is a guest post from Eldad Uzman, Automation Architect at Merck on how to distribute JMeter clients across different regions. You can read more from Eldad at Medium. When running load tests, you want to make sure your testing setup is as close to production setup as possible.  One of the many things that would contribute to high validity of load tests is the ability to distribute the load across different regions.  Thanks to RedLine13Read More →

Capacity Reservations for Large Load Tests

Scalability is one of the greatest strengths of using a cloud-based architecture.  However, there are occasionally limitations to how quickly we can scale. This is especially true for high volume load testing.  In these scenarios, we need to instantaneously scale a practically nonexistent cloud architecture to our maximum desired size.  It is not always guaranteed that cloud providers like AWS will have these resources idle and waiting in the necessary quantities.  In this post we willRead More →

Log4j and RedLine13

A zero-day vulnerability was uncovered in the ubiquitous Log4j library.  This dependency is used for event logging purposes (as its name suggests).  However, the vulnerability allows for remote access and code execution on affected machines.  The fix is to use an updated version of this library (2.15.0 or higher) which prevents this. We conducted an internal code review at RedLine13 and we do not use Log4j (or related dependencies like Log4php) directly within our systems.  JMeter does however use Log4j and thusRead More →

Parameterizing JMeter Tests from a CSV Data Source

When designing a load test, it is a common goal to emulate real-world requests to the best extent possible. It is easy to generate thousands of requests with JMeter. However, there is often a need to generate many different requests. Using parameterization, this is a straightforward task. In this brief post, we will illustrate the steps of parameterizing your JMeter tests from a CSV data source. Step 1. The first element we want to add toRead More →

Do-it-Yourself JMeter Testing

JMeter is one of the most popular load testing frameworks. However, to use JMeter at scale requires supporting infrastructure. In this post, we will be comparing and contrasting do-it-yourself JMeter testing versus managed JMeter load testing. With the rise of cloud computing architectures, it has become increasingly the standard to test using cloud-based resources. This means writing scripts to provision servers, coordinate load generators, and handle data collection.  Load testers using JMeter have two general options.Read More →
