Testing simulation of a road depicted in a testing environment turning into a real road When Field Testing Isn’t Possible, Use Simulation

Field testing is great for discovering different situations, but due to a variety of constraints, it may not always be possible. In such cases, simulation is useful to create a picture that mimics the real scenario. You can replicate hardware, operating systems, network ranges, and more, as well as nonfunctional areas.

Green "recycle" key on a computer keyboard 5 Tips to Turn Recorded JMeter Scripts into Reusable Tests

Using a tool like JMeter to execute load and performance tests while code is being developed is an inexpensive way to find issues early. But the recorded steps will need some work before they can be useful load and performance tests. Here are five suggestions to turn your recorded scripts into quality reusable tests.

Server stack What’s Different about Testing Serverless Applications?

Serverless computing is a DevOps technique that uses cloud-provided runtimes to execute code components in a defined workflow. Testing is easier in some ways with this model, but more difficult in others. Let's dive into the ways testing serverless applications and components is different from traditional architecture.

Left arrow painted on a wall 5 Ways to Shift Performance Testing Left

Performance testing is often a barrier to accelerating software delivery. Because you need a production-like environment, performance testing often waits until the entire application is complete. But you shouldn't wait until then to get started. You can begin testing earlier to reduce rework and address issues sooner.

A crowd of people walking in the street Crowdsourced Testing: Give the People What They Want

Crowdsourced testing is a great way to connect with users and ensure that the product idea, design, implementation, and nonfunctional elements meet their expectations—or, hopefully, even exceed them. But like any other test effort, crowdsourced testing is both a science and an art. Here's how to do it effectively.

Action-based test design checklist Leverage Your Actions to Get More Out of Test Automation

Test design can contribute greatly to how manageable and maintainable your automation is. Hiding detailed steps in actions makes their automation easier to maintain, and the high-level actions can be leveraged to define less common tests. Here's how you can write tests as a sequence of actions to improve coverage.

Mobile tester getting a positive result for a visual regression test on a smartphone Visual Regression Testing: A Critical Part of a Mobile Testing Strategy

Despite our best efforts to replicate customers' behavior in our test automation suites, teams often forget about nonfunctional requirements. An important one is visual perception—how users see and feel each application they use. Visual regression testing can fill a significant gap in user experience expectations.
