This directory contains additional examples of capability routing in Component Framework, with slightly modified packaging, using Subpackages, instead of bundling all components into a single package.
If these components are not present in your build, they can be added by appending --with //examples to your fx set command. For example:
$ fx set core.x64 --with //examples --with //examples:tests $ fx build
Use ffx component run (using either the C++ version or the Rust version) to create the component instances inside a restricted realm (for development purposes). The run command will also resolve and start the subpackaged_echo_realm component automatically:
$ ffx component run /core/ffx-laboratory:subpackaged_echo_realm fuchsia-pkg://fuchsia.com/subpackaged_echo_realm_cpp#meta/default.cm
$ ffx component run /core/ffx-laboratory:subpackaged_echo_realm fuchsia-pkg://fuchsia.com/subpackaged_echo_realm_rust#meta/default.cm
Start the client component instance by passing its moniker to ffx component start:
$ ffx component start /core/ffx-laboratory:subpackaged_echo_realm/echo_client
When the above command is run, you can see the following output with fx log:
[echo_client] INFO: Server response: Hello Fuchsia!
After running the example, you can remove the example realm using ffx component destroy:
$ ffx component destroy /core/ffx-laboratory:subpackaged_echo_realm
Integration tests using Subpackages are also available. Use the ffx test run command to run the tests on a target device:
$ ffx test run fuchsia-pkg://fuchsia.com/subpackaged_echo_integration_test_cpp#meta/default.cm
$ ffx test run fuchsia-pkg://fuchsia.com/subpackaged_echo_integration_test_rust#meta/default.cm
You should see the integration tests execute and pass:
Running test 'fuchsia-pkg://fuchsia.com/subpackaged_echo_integration_test_(rust|cpp)#meta/default.cm' [RUNNING] echo_integration_test [PASSED] echo_integration_test 1 out of 1 tests passed...
