What are the main use cases for VirtualBox in software development?

The main use cases for VirtualBox in software development include testing across multiple operating systems, creating isolated development environments, and setting up sandboxed testing environments. VirtualBox gives developers an easy time running several operating systems on one machine for testing applications to run well in different environments, such as Windows, macOS, and Linux.
VirtualBox also serves as a way of providing sandboxed development environments where a developer could set up a VM, installing all the required tools, dependencies, and configurations for a project without touching the host. It is also used for performing sandbox testing: it allows developers to safely try new features or updates in an isolated environment sheltered from the production system. In fact, all these capabilities make VirtualBox very helpful in cross-operating system development, debugging, and experimentation.
