In modern software, users rarely complain about what an application does—they complain about how long it takes . In systems built on microservices, where a single user request may travel through dozens of services, latency becomes one of the most critical and misunderstood challenges. This is where Latency Testing steps in as a quiet but powerful safeguard of user experience. Why Latency Matters More in Microservices Microservices architectures break applications into small, independent services that communicate with each other over the network. This approach improves scalability and team autonomy, but it also introduces complexity. Every call between services adds network delay, processing time, and the potential for cascading slowdowns. In a monolithic system, latency is often localized. In microservices, latency co...

  Code stability and reliability can be a concern when building front-end applications. As web applications become more complex, web developers require a test framework that is simple yet incredibly powerful. This is where Jest testing comes in handy. Jest is a testing type designed and maintained by Facebook, which is already the ideal tool for most front-end programmers needing precise, fast, and robust test coverage. Learning Jest Testing Jest Testing is a JavaScript testing framework that eases unit testing and integration testing for developers. The simplicity of use and a wide variety of features make it a simple tool to use for testing React apps but works great for vanilla JavaScript projects and with other front-end libraries. The number one issue with Jest is how easy it is to start, making it inconvenient for developers to get started on testing their project with the libraries and frameworks they are using. Unlike other test libraries that are of a later age, Jest is eq...
