Express Testing: Getting Started Quickly With Examples

Before we talk about Express testing, it’s vital to skip fast-forwarding on what Express apps are. Express, a Node.js web application framework, can provide a minimalistic and flexible solution for mobile and web apps. The major use-case served by Express is to offer server-based logic for mobile and web apps when we use it everywhere.

Best Android Emulator for Linux

Linux has captivated users across the world, owing to its paramount features such as readily available source code, lightweight, higher network performance, and availability of distros such as Ubuntu, Arch Linux, and Fedora. Even though Android consists of a Linux kernel, the core features are Java-written. It’s a well-known fact that Linux doesn’t support Java code. This is the reason why Android apps aren’t supported on Linux.
