Which command would you use to transfer a completed application from a development to a testing environment?

To transfer a completed application from a development environment to a testing environment, the Export command is utilized. This command packages the application and its associated components into a single file that can be moved efficiently between different environments.

When you export an application, you create a deployment artifact that captures the entire application structure, including processes, interfaces, and data types. This exported file can then be imported into the testing environment, effectively allowing for a seamless transition of the application without needing to recreate components manually. This process is essential for maintaining consistency and ensuring that the version of the application being tested is the same as what was developed.

Options like Duplicate and Download do not correctly serve this purpose. Duplicating would typically create a copy within the same environment rather than facilitating movement between environments. Downloading does not provide a structured way to transfer all necessary components since it often refers to downloading files rather than specifically handling the application package. The New Application option suggests the creation of a new application rather than the transfer of an existing one, which is not relevant in this scenario.

Thus, Export is the appropriate choice for transferring a completed application effectively to a testing environment.
