Load testing, perhaps more than any other form of testing, is one of those activities that you either choose to do well or risk a result that leaves you worse off than not doing it at all. Half-hearted attempts at load testing yield "results," but too often those results are inaccurate, leading to a false sense of security for anyone who trusts them. This, in turn, leads to the release of applications that are not adequately tested and that experience performance problems soon after entering production. I was reminded of this not long ago, when I worked with a customer who related an experience that may sound familiar to many of you. This customer was a test engineer for a bank that had recently merged with another bank, effectively doubling their customer base. He was part of a team responsible for load testing a new web application that would serve customers from b... (more)

Best Practices for Load Testing Mobile Applications | Part I

Mobile applications and mobile websites have become a major channel for conducting business, improving employee efficiency, communicating, and reaching consumers. In the past, mobile played a smaller role in business applications, so performance issues and outages were less of a concern. This is no longer the case. Today, performance problems with mobile applications lead directly to revenue loss, brand damage, and diminished employee productivity. Part I of this article discusses the differences between testing traditional web and mobile applications, specific challenges assoc... (more)

Benefits of Load Testing in the Cloud (Part 1)

Many companies have moved applications to the cloud as a way to reduce capital expenditure while improving IT focus and effectiveness. End users see the cloud as a way to access their documents and applications remotely from anywhere and from any device. IT managers see the cloud as a means of rapidly adapting their infrastructures as needed via virtualization and a pay-per use-model. But what about load testing engineers? Can they seize the opportunities afforded by the cloud to better test the performance of web applications? As with past overhyped trends in IT, it is importan... (more)

Challenges and Best Practices for Load Testing with the Cloud

In Part 1 I described how the cloud is revolutionizing load testing and the advantages it provides to ensure that your web applications perform well in production. We also looked at what capabilities you should seek out when selecting a load testing solution. In Part 2, I will offer the limitations of a test strategy that relies solely on cloud-based testing, highlighting the need for a complementary internal load testing solution. I will also discuss several best practices for load testing in the cloud. Understanding how to apply the right tools and practices to make the most o... (more)

Best Practices for Load Testing Mobile Applications | Part 2

Mobile applications and mobile websites have become a major channel for conducting business, improving employee efficiency, communicating, and reaching consumers. In Part I of this article we discussed the differences between testing traditional and mobile applications, specific challenges associated with mobile load testing, mobile testing basics and best practices for recording mobile load test scenarios. In this Part 2 of the article, we will look at how to conduct realistic tests and how to best analyze the results. How to Run Realistic Load Tests Once you've recorded a mobi... (more)
