People often ask if they can use Selenium for load testing. The Selenium website says: Performance testing using Selenium and WebDriver is generally not advised. Not because it is incapable, but because it is not optimised for the job and you are unlikely to get good results. The site goes on to recommend JMeter. We would say that Selenium can be used for load testing with limitations as many RedLine13 customers do. RedLine13 is a cloud-basedRead More →

RedLine13 was built with a focus on JMeter cloud-based load testing, allowing you to scale your JMeter tests to any size. Tests run on RedLine13 work with Apache JMeter and other open-source platforms and plugins.

At the top of every completed load test, is the test “Summary“. This area provides an at-a-glance view of the most pertinent information concerning the overall performance of your load test. Each of these blocks and the data they display is summarized in the table below. Summary Block Descriptions Block Description Percentiles The top row of blocks (blue in color) appears only when the calculation of percentiles has been enabled. Failed/Threads This split field contains twoRead More →

Enabling Public IPs on your RedLine13 Load Generators

One thing you must be aware of is ensuring that your load generators are visible to RedLine13.  This is accomplished through assigning public IP addresses.  In this post we will show you how to configure that and successfully run your first load test. What is a Public versus a Private IP? A public IP address refers to its ability to be accessed from external networks – e.g., the internet.  On the other hand, a private IPRead 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 →

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 →
