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 →

What are WebSockets The WebSockets specification enables Web applications to maintain bidirectional communications with server-side processes, this specification introduces the WebSocket interface. In plain words: You can maintain a persistent connection between client and server which is available for data communication anytime while the connection is open.  Some resources and tutorials include WebSockets.org HTML5Rocks Introducing WebSockets Using JMeter to Create WebSocket Requests By default, JMeter does not provide a websocket sampler. However, the JMeter community is pretty powerful.   MaciejRead More →

HTTP Cache Manager – Why I should use it and an example. JMeter is not a browser, but JMeter provides config elements which helped to mimic the browser behavior and make your tests more realistic. “Cache manager” is used to simulate the browser caching behavior in Jmeter by adding caching functionality to HTTP requests within its scope. In general, a browser caches files locally including any documents that make up a website, such as HTML files, CSS styleRead More →

Apache JMeter provides a variety of assertions which are helpful to apply a few checkpoints with each request. However the assertion must be carefully used because it consumes resources (memory or CPU). Below is a list of JMeter assertions: Bean shell assertion: allow the user to write their bean shell script to perform assertion. Compare assertion: used to compare sample results within its scope Duration assertion: check the response time of the request, if the request takes longer timeRead More →
