Tutorials, articles, tools and resources on how to perform load testing in software testing.
It’s 4am and you don’t know it, but you’re about to get three times the traffic you were expecting. Is your service ready to handle it? Systems are only as scalable as their weakest component. Large scale load testing in production is the best (and surest) way to ensure that services can truly scale to the unexpected and Amazon Web Services (AWS) can help you.
In the context of Java EE 6, unit tests are nice but worthless. Unit and integration tests execute chunks of the business logic in a single thread. Back-end resources and shared states are simulated with mocks.
James Waldrop of Twitter discusses the tools, process and philosophy that goes into performance testing at Twitter. Particular emphasis will be placed on the Iago open source load testing library, which he wrote to enable Twitter’s engineering teams to perform load tests before deploying code to production. This presentation dives into implementation details of some of these tests (including source code) and how complicating factors such as OAuth and arbitrary Thrift protocols are managed.

Now that a lot of software applications are directly visible from customers and that a failure has broader consequences, load testing has gained an increase importance in the software testing domain. In this Phd thesis, Zhen Ming Jiang propose an approache for the automated and systematic analysis of load testing logs.
This article by Benjamin Day recommends to use custom counters when you perform load testing. It discusses how Visual Studio 2012 load-testing features call help you solve performance problems. The article describes how to set up Visual Studio to perform load testing, particularly the ability to capture Windows Performance Monitor Counters (PerfMon Counters).
Learn how Telerik Test Studio’s performance testing and just-released load testing features can help you detect bottlenecks in your system’s performance and answer business-critical questions about your ability to handle large amounts of traffic. This webinar focuses on Test Studio’s Performance and Load Testing features. It presents how these features can help you respond to questions from management like “Will our site be able to support traffic after this new product’s launch?” and “Are our customers happy when they are using our site during normal and high traffic times?”
This blog post discusses the load testing considered as a science and an art. It provides some interesting hints gathered from experience, such what it defines a golden rule of load testing “By the time the system is mature and stable enough to test, it’s time to deliver already”. It discusses also the fact that load tests are static, but the reality is not. Finally, how close you try to be to reality when you perform load testing, you will certainly not be able to replicate it completely.
