Apache JMeter offers testers a multitude of different features that we can use to create and run JMeter tests. One of these features is the ability to record JMeter scripts with a mobile device by connecting the device to a proxy that you setup inside JMeter. Once we set up this proxy, we can then connect our mobile device to it in an effort to test various iOS and Android mobile applications. We have previouslyRead More →

JMeter 3.0 is a major update from the community and one that is years in the making. For any open source project to pull off a release of this size is no easy accomplishment. Contributions from 26 individuals are mentioned and we are sure many good discussions in the forum drove ideas and collaboration. With this release, JMeter continues to solidify itself as the leader in performance testing; a workhorse that has been providing value for moreRead More →

The Selenium+JMeter plugin was built for QA teams to support functional and performance testing from the same test plan. Our plugin captures Selenium test playback which can then be downloaded as a standard JMeter .jmx file. This can be uploaded back into JMeter or run via a cloud test using RedLine13 or other cloud load testing providers. To help you get started, we will take a brief look at how to setup and use our FirefoxRead More →

Typically, whether we are starting a load test or developing a strategy used for load testing, we often come to wonder about the specifics of the user’s usage patterns. “What exactly are users doing once they’re on our website?”, is a very common question that we often hear. Thankfully, web server access logs can help us answer this question and others due to the fact that these logs contain a range of information like HTTP requests,Read 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 →

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 →
