class RealmProxy

This protocol mediates a test suite's access to a component under test.

A RealmProxy is a test harness which allows some test suite to create instances

of the component(s) under test on demand. Most importantly, the test suite

does not have to know which components are created or how they are created;

It is only required to know which capabilities the components expose.

For example, a generic test suite for Fuchsia filesystems can use the RealmProxy

protocol to spawn components that serve protocols from the fuchsia.io FIDL

library. The test suite doesn't need to know which filesystem it's testing

or how the filesystem is initialized. It just needs to call

[ConnectToNamedProtocol] with the name of a fuchsia.io protocol and start

testing. By running this test suite with different proxies that initialize

different filesystems, we can use the same suite to validate each system.

WARNING: RealmProxy will soon be deprecated. Prefer to return a

fuchsia.component.sandbox.DictionaryRef and install that into your namespace.
