Forward Being able to recognize and understand major industry shifts and trends is something we value highly here at RedLine13. It allows us to continue to not only improve upon ourselves, but to also keep our readers and users informed and up-to-date with what’s going on in the world of load/performance testing. This is why we have introduced a new blog “mini-series”, if you will, which will focus entirely on important industry trends. For the first entryRead More →

How to use the Duration Assertion to fail a test? The Apache JMeter Duration Assertion documentation http://jmeter.apache.org/usermanual/component_reference.html#Duration_Assertion  Definition: The Duration Assertion validates that each response is received within a given amount of time. Any response that takes longer than the given number of milliseconds (specified by the user) is recorded as a failed response. Parameter Usage Duration in milliseconds If the requests take longer than ms supplied, Sampler is considered failed Apply to Main and Sub-Samples Main SamplesRead More →

In many test scenarios, you want to hit an internal application running on a private AWS subnet. The application access is managed by an internal ELB with a distinct security group.   A quick way to enable RedLine13 and other load testing agents is to use a security group with only outbound access.  Then allow the Internal ELB to be accessed by servers in this security group.  These test agents will need a public IP, but youRead More →

AWS has made networking configuration many times simpler over managing your hardware. Anyone now has the power to create a network, but with such power comes a lot of mistakes.  One of the challenges comes with load testing internal applications hosted on AWS. This article is a general guide which could help anyone testing internal applications. In the end, we demonstrate launching a RedLine13 load test within AWS private subnet communicating externally through an NAT gateway. Note:Read More →

We are happy to call this our Valentine’s release, all features are driven by user requests.   As always feedback and new ideas welcome. Simple Test Plan now has RampUp time.

RedLine13 Just Got Real RedLine13 started from a need to support 50,000 users registering in minutes.   The load testing market has been full of large, expensive, closed, and locked-down providers.   There was no way for RunSignUp to scale without a large investment for initially a point in time need.  Stephen Sigwart and Bob Bickel decided they needed to build something quick for their business.  Afterwards, they realized they had something special – easy, inexpensive, and rapid load testing.  Read More →

From the Open Source Load Testing presentation http://www.slideshare.net/richardfriedman/open-source-load-testing Perhaps in a perfect world, every time code is submitted and reviewed, a Jenkins job kicks off a load test against your specific change.  However, in reality, this has quite a few issues: Too early.  Load testing too early in your process is noise Time.  Realistically, most projects are not scoped with time for this Scope.  Changing a readme file should not generate a load test For me, I have foundRead More →

From the Open Source Load Testing presentation http://www.slideshare.net/richardfriedman/open-source-load-testing Everything else was build up to the review of this slide. What is available in  open source load testing tools?  There are so many ways to slice and dice all the great open source projects and this slide is not a deep review or demo of each project.  I looked at the dimensions of the projects in terms of content covered in this presentation. Distributed.  Does it support scaling loadRead More →

From the Open Source Load Testing presentation http://www.slideshare.net/richardfriedman/open-source-load-testing In the previous (#6 How it Used To Work), I told a story of how we put our desktops, yes desktops, to work. However, in today’s world, there are many more options.   You can rent agents from other commercial load testing clouds or you could use your own cloud to generate the test load.  Each team can now have their own environment and the dependency friction gets removed.
