Posted in Load testing by testing in London on November 28, 2011

What are the benefits of cloud-based load testing. According to Computerworld UK they are:

  • Assured performance
  • Worldwide readiness
  • Cost control
  • Enterprise application coverage

SOASTA, the cloud-based performance testing provider, has added Selenium-based functional testing capabilities to its SOASTA CloudTest Platform. The new SOASTA functional testing solution, which is available in all CloudTest editions, extends the open source Selenium testing tool with more accurate test recording, a visual test creation environment, distributed test execution, and powerful analytics.

Designed for testing modern, browser-based Web apps built with technologies such as HTML5 and easily integrated into continuous integration servers such as Hudson and Jenkins, SOASTA’s functional testing solution enables both quality assurance (QA) and software development teams to execute more accurate tests with unparalleled speed and agility.

Load testing and disasters

From TMC

“…the harsh weather that “never seemed to go away” held the transportation infrastructure and its operators in a stranglehold. And then that Icelandic volcano thing happened.

Transportation industry websites were overwhelmed with the massive traffic surge and some went down. But Swedavia, the country’s largest airport operator, had thought ahead and implemented a cloud-based offload service. So the Web traffic was redirected, within minutes, to a cloud-based high performance delivery network…”

Cloud based application performance testing

Posted in Load testing by testing in London on May 3, 2011

There is a webinar on May 10 2011 covering cloud based application performance testing. That’s testing the performance of applications that are in the cloud, rather than using cloud based performance testing for applications (that aren’t necessarily in the cloud).

“Join this webinar to see how the OpSource Cloud platform, combined with ZSL’s ZLOAD testing framework, provides clients with a cost-effective solution to conduct on-demand performance and scalability testing on an application. Topics covered will include:

  • Types of tests most important for testing applications in the cloud.
  • Using a wide range of performance tests (load, stress, reliability, spike, etc.) to generate a thorough understanding of system behaviour.
  • A general approach to performance testing.
  • A live product demo of ZSL’s ZLOAD testing framework.”

SilkPerformer Cloudburst

Posted in Load testing by testing in London on April 18, 2011


Web is the future of any economy, and, as organizations develop web applications, that will be used by several thousands of users worldwide. The traditional methods of testing require far too much hardware and are not able to scale to meet the demands of today’s web applications.

Micro Focus recently launched SilkPerformer CloudBurst, a peak-demand load-testing capability based on Micro Focus Enterprise Cloud Services (ECS) technology; SilkPerformer CloudBurst utilizes the cloud to meet these resource demands using a flexible, pay-as-you-go, consumption-based pricing model.

By extending SilkPerformer’s on-premise model with cloud load-generation technology, CloudBurst enables customers the flexibility to drive load from either on-premise or in the cloud or both at the same time. This model also has the advantage of being able to monitor the underlying systems and provide performance diagnostics with one integrated product.

Spike Testing

Posted in Load testing by testing in London on April 6, 2011

Spike testing is used in load and performance testing. These tests are normally based on real world or projected work loads with focus on extreme load/performance conditions. Provides a good indicator if the system can handle unexpected volumes of users/connections and what the existing limitations are based upon current operational environment. “

From Projectmanagementitoolbox

Spike testing is where operations are co-ordinated at significant points to highlight errors which occur only during concurrent usage.

From Load test terms

Spike testing, as the name suggests is done by spiking the number of users and understanding the behavior of the application; whether performance will suffer, the application will fail, or it will be able to handle dramatic changes in load.

Cloud load testing

Shrimathi Ambastha, director of technology, VMware India, agrees, “The efficiency of any applications and infrastructure, get exposed only when it undergoes load and performance testing. The choice of the testing algorithm and tools has impacted the way in which applications and infrastructure perform.” Apparently, cloud testing has traditionally been used to refer to load and performance testing of websites. However, with increasing maturity of technology, all kinds of enterprise software can be tested for functional and performance issues before going in for full fledged enterprise deployment. Also Dhiraj Sinha, executive director, applications technology group, Dell Services says, “One could look at 2 aspects of cloud testing, a) Testing the cloud infrastructure and b) testing applications for delivery over the cloud , for instance, Software-as-a-service ( SaaS ) model. In both cases, the variables that need to be considered during testing increase significantly as compared to the traditional testing as every layer can be virtualized and therefore, comprehensive testing prior to deployment of the infrastructure as well as the applications is a necessity.”

Scalability testing

From Photo Hot

Systems that work well during development deployed on a small scale can fail to meet performance goals when the deployment is scaled up to support real levels of use.

An apposite example of this comes from a major blue chip company that recently outsourced the development of an innovative high technology platform. Though development was behind schedule this was deemed acceptable. The system gradually passed through functional elements of the user acceptance testing and eventually it looked like a deployment date could be set. But then the supplier started load testing and scalability testing. There followed a prolonged and costly period of architectural changes and changes to the system requirements. The supplier battled heroically to provide an acceptable system until finally the project was mothballed.

Testing web applications

From PR Log

Phil Lew, CEO of XBOSoft, recently spoke at the Applied Sciences College of Beijing Union University in Beijing, China. Students at the university pursuing associate and bachelor degrees in computer science and software engineering were among the attendees. Lew’s presentation addressed the topic of testing web applications and in particular, the special considerations required for performance testing web applications when there is increased user group variation. “Testing web based applications requires a different approach and mindset when compared to the conventional software applications of yesterday. User diversity, behavior and the platforms they use are all magnified” explained Lew. “Performance deserves special emphasis as even the most prolific feature set and functionality will be termed a failure if users walk away due to slow performance. And now with SaaS business models, they can leave and sign up with another software vendor in minutes” added Lew.

Stress testing Storage

From Windows IT Pro

Microsoft will soon offer the new File Server Capacity Tool (FSCT) for this purpose, and as of October 2009, it’s already available as a release candidate at The tool isn’t a planning tool: those would typically let you say how many users, shares, and so on you need to support and then generate a server specification. This tool runs on your file server and stresses it with emulated workloads, then tells you what capacity the file server can support in terms of maximum users, throughput, and response time, and tells you where the bottlenecks are. FSCT is a command line utility without a GUI, so it’s very much targeted at IT professionals and solution providers.
