Pitfalls of Selenium Load Testing

Tests created with Selenium WebDriver replicate the user experience from the perspective of the UI.  It can be thought of as a top-down approach whereby it accurately replicates the behavior of an end user. Running through a browser instance such as Chrome or Firefox, the test process itself interacts with the actual user interface elements of a target test application. This is in contrast to many other testing frameworks.  One of the most popular is JMeter,Read More →

As we have previously examined, the cloud has opened up many new doors within the world of performance testing. We are now seeing a new use case for cloud performance testing emerge, not simply a means to validate scale, but as a service to validate deployment options based on size, scale, and cost: load testing for capacity planning. This trend is a sign that the power of pricing/performance has shifted from operations teams to development andRead More →

For many first-time testers or even experienced QA managers, load testing can be a daunting task. But it certainly doesn’t have to be, especially when there’s a passionate and active community of testers out there providing others with a host of resources. Jason Lotito, the DevOps lead architect for MeetMe, gave a few presentations awhile back on cloud load testing. He even goes over a few sample tests and shows you how it’s done. We wanted to passRead More →

From the Open Source Load Testing presentation http://www.slideshare.net/richardfriedman/open-source-load-testing   If you have been through the process of build and running load tests, I am sure you have gone through all the emotions that come with it. From the fun of taking down your site or API, to the agony of not knowing where the bottleneck is, and eventually the eureka moment when you resolve the issue and run your next load test.  Here are some of my emotions.Read More →

From the Open Source Load Testing presentation http://www.slideshare.net/richardfriedman/open-source-load-testing In this slide we will examine load testing where the application is a black-box.  When we run our test on that black box we are looking to expose a performance bottleneck, typically this bottleneck will emerge as either performance or throughput issues. Performance. Measuring the response time of requests or test plans.  Typically measured in ms or s, but it will be specific to your test plans. Throughput.  Measuring theRead More →
