Multi-surface applications

A non-transitory computer-readable storage medium storing one or more programs configured to be executed by one or more processors of a computer system, the one or more programs including instructions for:

• receiving, from a first user, an application model for storing on a host platform, wherein the application model is associated with a set of capability data, a set of functionality data, and a set of surfaces;
• after receiving the application model, accessing the set of capability data and the set of functionality data associated with the application model to generate a collection of user interfaces and functionality to verify the application model in accordance with a plurality of predefined benchmark surfaces associated with the host platform;
• in accordance with a determination that a predefined benchmark surface of the plurality of predefined benchmark surfaces corresponds to a first surface of the set of surfaces, causing a first execution in a first sandbox of a first set of user interfaces and first functionality associated with the application model, wherein the first sandbox is based on the first surface;
• in accordance with a determination that a predefined benchmark surface of the plurality of predefined benchmark surfaces corresponds to a second surface of the set of surfaces, causing a second execution in a second sandbox of a second set of user interfaces and second functionality associated with the application model, wherein the second sandbox is based on the second surface, and wherein the first set of user interfaces and first functionality are different from the second set of user interfaces and second functionality;
• and
• in response to the first execution and second execution performing successfully, storing the application model on the host platform for installation by other users of the host platform.

A method, comprising:

• by a computer system:
• receiving, from a first user, an application model for storing on a host platform, wherein the application model is associated with a set of capability data, a set of functionality data, and a set of surfaces;
• after receiving the application model, accessing the set of capability data and the set of functionality data associated with the application model to generate a collection of user interfaces and functionality to verify the application model in accordance with a plurality of predefined benchmark surfaces associated with the host platform;
• in accordance with a determination that a predefined benchmark surface of the plurality of predefined benchmark surfaces corresponds to a first surface of the set of surfaces, causing a first execution in a first sandbox of a first set of user interfaces and first functionality associated with the application model, wherein the first sandbox is based on the first surface;
• in accordance with a determination that a predefined benchmark surface of the plurality of predefined benchmark surfaces corresponds to a second surface of the set of surfaces, causing a second execution in a second sandbox of a second set of user interfaces and second functionality associated with the application model, wherein the second sandbox is based on the second surface, and wherein the first set of user interfaces and first functionality are different from the second set of user interfaces and second functionality;
• and
• in response to the first execution and second execution performing successfully, storing the application model on the host platform for installation by other users of the host platform.
