Feature flags are a necessary part of your Continuous Delivery (“CD”) pipeline. In fact, as your team grows, you can’t do CD without feature flags. This article provides best practices on when to use feature flags.

Since joining Split, it has been clear that feature testing is the fundamental building block of our software development process. We deploy unit tests to validate discrete parts of business logic, end-to-end tests to monitor our APIs, automated usability testing to maintain our user experience, and entire network of bots…

In this episode we are covering how to write modular testing code, maximizing reusability so your framework can adapt quickly to changes.

There are two primary options for icon systems: scalable vector graphics (SVG) and icon fonts. When considering the best solution, a developer has to determine which is most performant, with the highest quality, at the lowest cost of development. Having compared these options at Split, we believe SVG icons are…

In the world of Selenium usability testing, many intermittent failures are caused by elements not showing up in time or not being enabled when the test tries to access it. Adding extra checks on your tests might slow down your suites, but it’s a small price to pay for reliability when coding for web or mobile SDK.

End to End (E2E) WebDriver Testing is a two-edged sword; it can be the hero, saving you a lot of time during regression testing and preventing faulty releases, or it can be the villain, slowing down the development and release process with flakey, hard to maintain and time-consuming suites that…

​Why does infinite scrolling matter for SaaS software? Frankly, handling large datasets in the browser could result in serious performance issues. Presenting users with a decently big dataset wouldn’t be a great user experience either (imagine scrolling through a list that contains 15,000 elements!). To avoid these headaches, a better…

The new era of software faces a new major challenge: Distribution. As we are thinking about creating applications to run on different third party services or devices like smartphones, watches, TVs, notebooks, tablets, even “things” – Engineers and architects are searching for ways to develop for distribution while continuing to…

When measuring latency, keeping track of individual measurements is a good, first-pass solution. It gives you the flexibility to perform aggregations at a later time and experiment with different ways of constructing histograms and explore metrics in specific time windows, among other tests.
