Project Portability is the ability to move an entire project, including all of its components, from one environment to another. This includes the ability to move the source code, tests, resources, and configuration files from one system to another. It also includes the ability to move the project from one development environment to another, such as from a development computer to a production server. Project Portability can be divided into four main types: 1. Source Code Portability: The ability to transfer source code from one system to another. This includes the ability to move code between different programming languages and platforms. 2. Resource Portability: The ability to move resources, such as images and data files, from one system to another. 3. Test Portability: The ability to move tests, such as unit tests, from one system to another. 4. Configuration Portability: The ability to move configuration files, such as configuration settings and environment variables, from one system to another.
