It’s a given for web and mobile application development that performance testing is critical to application success. Yet, for organizations wishing to customize third-party (3P) software as a service (SaaS) rather than running it out of the box as written, performance testing can be problematic.
Switching from a legacy system to a composite application? It can be tricky, because the transition requires a lot of restructuring. To be sure you’re conducting the most streamlined, complete transfer possible, you need to focus on key performance indicators.
Much has been written about the complexity of application performance testing. The breadth and scope required to effectively test application architecture and transaction flow can make it a daunting effort, especially with service-oriented architectures where hundreds or even thousands of third-party services and components are added to the mix.
In order to understand if performance matches needs, testing is a necessity. While there are many areas that help define testing parameters, three overarching testing concepts must be addressed in order to provide appropriate performance for modern applications: your users, your data, and your environment.
You have a new code release and two weeks for performance testing. What tests do you run? One common answer is to run the same tests you used on the last release (after fixing your scripts, of course). This is a good way to make sure the new release can handle the same load as the last one. However, this approach ignores a key fact: loads change.
Web services—software code that enables the client application and the services to interact successfully—are literally the building blocks of application function. To ensure application performance and minimize user problems in production, each web service should be tested—and its functionality and connectivity trusted—before the developing organization integrates it into the application.
It simply isn’t feasible to test every possible user scenario with a new app, and the testers who already know how the app should perform can’t approach using it the same way as someone unfamiliar with the process. Enter crowdsourced testing, where you gather a customizable pool of people from outside your organization to test your apps for defects and usability.
