Power button Simplify Continuous Operation Tests with a Periodic Reboot

Continuous operation tests find important bugs, partly as a result of their long operation and partly by increasing the probability of finding statistical bugs. However, CO tests have their own downsides. Mandating a periodic reset or reboot can work around these issues, as well as save time and cost for testing, reproduction, debugging, and fix verification.

Monitoring dashboard with criteria set up Solving Production Issues Using Testing Tools

Standard web-monitoring tools can ping webpages and verify that they’re responding, but they don’t alert you to an issue. But you can use the technology in load testing to monitor your sites by running an interactive script that can detect issues and generate emails as needed. It runs constantly like a silent sentry, never sleeping or taking a vacation, improving your sites' reliability.

DevOps collaboration DevOps: The Pathway to Stellar Digital and Business Results

DevOps is the key to unifying technology with business results. Customers abandon apps and sites if their expectations are not met almost instantly, so issues must be resolved earlier in the pipeline before end-users are impacted. This article highlights the need for adopting a DevOps culture and some best practices for doing so.

Real-Time Test Analysis Why Continuous Delivery Is Nothing without Real-Time Test Analysis

Pushing frequent releases of high-quality software to customers is beneficial for everyone. But setting up a continuous delivery pipeline is about more than speed. How do you ensure that things don’t start breaking all over the place? Viktor Clerc shares some real-world methods of accurately measuring quality and building it into the pipeline.

Using Agile and DevOps to Achieve Quality by Design Using Agile and DevOps to Achieve Quality by Design

When software nears completion, it is the wrong time to focus on quality. Product delivery improves if you invest in a plan, validate in small increments, and focus on continuous testing.

Your Professional Responsibility for Security and Performance

It is Johanna Rothman's belief that security and performance are no longer nonfunctional requirements in modern-day software development. Instead, we must prepare to accommodate security and performance needs in all projects.

STARCANADA 2019 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.

STARCANADA 2019 How Fast Is My App? Performance Testing 101
Slideshow

Product owners and stakeholders love to ask about performance. “Is the app fast? How fast?” What do those questions even mean? Are they interested in the number of transactions per second? The time for the page to load? How many users it can support at once? Performance testing is a much broader topic than just being able to say an application is “fast” or “slow.” There is load testing, stress testing, and soak testing. You can measure transaction times, concurrency, and capacity. You can address some performance issues with more systems, others with more memory or faster processors or a better network. It all depends on what you mean by "How fast?" Join Gene Gotimer as he showcases open source tools like JMeter and Gatling to measure different types of performance testing. He'll also discuss how Firefox and Chrome can show what the user experience is like in terms of performance.

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.
