As digital transformation accelerates, the importance of specialized testing services has grown exponentially. While still relevant, traditional functional testing no longer suffices for businesses aiming to deliver robust, seamless applications that meet modern user demands. Specialized testing—spanning performance, cognitive, and UX domains—is now critical in ensuring digital ecosystems’ resilience, security, and usability.

In the previous part of this series, we discovered how to create persistent connections in Rack in theory, but now we'll put what we learned into practice. The web has two formalized specifications for communication over a persistent connection: server-sent events (SSEs) and WebSockets. WebSockets are widely used and highly popular, but SSEs are far less well-known. Let's explore them first.

Unit tests are essential for increasing the test coverage of a backend application, ensuring its reliability, functionality, and robustness.

When writing test automation scripts in Selenium Python, verifying that the actual outcomes match the expected results is crucial. This is where assertions come into play. Assertions help ensure that your application is working as intended by checking specific conditions and halting execution if they fail. In this blog, we’ll break down the concept of assertions in Selenium Python, provide some easy-to-follow code examples, and explain how they can make your test scripts more robust.

We’re not trying to coin a new era, but it’s pretty clear now how ordering groceries online has become a go-to option for Gen Zs and Millennials alike. Wherever you are, there’s likely a grocery delivery service that’s ready to bring what you need right to your door.
