Routing Example

This directory contains an example of capability routing in Component Framework.

Building

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

Running

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 echo_realm component automatically:

  • C++
$ ffx component run /core/ffx-laboratory:echo_realm fuchsia-pkg://fuchsia.com/components-routing-example-cpp#meta/echo_realm.cm
  • Rust
$ ffx component run /core/ffx-laboratory:echo_realm fuchsia-pkg://fuchsia.com/components-routing-example-rust#meta/echo_realm.cm

Start the client component instance by passing its moniker to ffx component start:

$ ffx component start /core/ffx-laboratory: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:echo_realm

Testing

Integration tests for echo server are available in the echo_integration_test package. Use the ffx test run command to run the tests on a target device:

  • C++
$ ffx test run fuchsia-pkg://fuchsia.com/echo_integration_test_cpp#meta/echo_integration_test.cm
  • Rust
$ ffx test run fuchsia-pkg://fuchsia.com/echo_integration_test_rust#meta/echo_integration_test.cm

You should see the integration tests execute and pass:

Running test 'fuchsia-pkg://fuchsia.com/echo_integration_test#meta/echo_integration_test_rust.cm'
[RUNNING]	echo_integration_test
[PASSED]	echo_integration_test
