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 associated with mobile load testing, mobile testing basics and best practices for recording mobile load test scenarios. In Part II, we will look at how to conduct realistic tests and how to best analyze the results. Application developers have long understood the need for load testing conventional... (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)

Testers Are from Mars, Developers Are from Venus

Developing with Performance Testing in Mind A tester friend of mine recently came to me with a complaint that I think is fairly common in the testing community. He said, "Every time there is a new release of the software for us to test, we have to rework our testing scripts." I've heard this complaint throughout my career, not only in performance testing but in functional testing with automation tools as well. This state of affairs arises from three fairly straightforward observations: Change is inevitable. Everything changes, and in no industry is this more apparent than software... (more)

Learning to Expect the Unexpected: Load Test Before It’s Too Late

At times, I can be a bit of a procrastinator. If there is no pressing need to clean out the garage this week, shop for holiday gifts, or do my taxes, I can easily be convinced to let it go until next week or next month. Inevitably, though, something happens that makes me wish I hadn't delayed quite as long as I did. The garage gets flooded, for example, and the boxes that I had been meaning to organize get soaked and destroyed... or my Valentine's Day gift doesn't get shipped in time and I'm left holding the bag. I'm sure many of you can think of your own examples. Unfortunatel... (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)
