A Comprehensive Guide to Responsive Testing Responsive testing ensures websites look and function well across devices by testing layout, functionality, and performance on various screen sizes and browsers. It's crucial for consistent user experience, navigation, image display, and website robustness. Testing methods include browser developer tools, real devices, usability testing, and performance testing. Common challenges include outdated browsers, device-specific behaviors, and network speeds. AI, Machine Learning, and Real User Monitoring are emerging trends in responsive testing. |

Don’t Let Load Testing Lead You Astray While traditional, "closed system" models might seem familiar, they miss the unpredictable nature of real user arrivals. This article highlights how open system models, which mimic real-world user behavior, expose performance bottlenecks at high load that closed models can't catch. Remember, arrival rates, not virtual user counts, are the key to unlocking accurate load testing results. |

Performance Testing in a Containerized World
Slideshow
Containerizing applications introduces major changes to the way we run those applications. We can now share infrastructure and resources, but this introduces the need to control the way resources are used—from a sanity perspective first and a financial objective second. |

Continuous Performance Testing: A Tale of Two Worlds
Slideshow
Once upon a time, in a land far away, application performance was a differentiator in the market. But in today's competitive landscape, having a highly responsive and scalable application is a basic expectation. Performance no longer lives on the fringe of the quality world. |

Finding Performance Issues Early with JMeter
Slideshow
Nonfunctional tests like performance tests are often left until the end of the delivery cycle because they can be expensive in terms of time, resources, and effort. However, performance issues can be difficult to resolve when found late in the software development lifecycle. Apache JMeter is an open source tool designed to load test functional behavior and measure performance. JMeter can be used to develop, manage, and execute load and performance tests while the code is being developed, rather than waiting to do performance testing until just before release. By using it early in your delivery pipeline, you can find and resolve performance issues as soon as they are introduced. Join Bob Foster as he shows how to use JMeter, design test scenarios, parameterize and seed tests, and execute those tests within Jenkins as part of a CI/CD pipeline. |
