This directory contains an example of routing service capabilities in Component Framework and aggregating multiple service instances from a component collection.
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
This example is built to run inside the Test Runner Framework. Run the example using the following command:
C++
$ ffx test run fuchsia-pkg://fuchsia.com/service-examples-cpp#meta/default.cm
Rust
$ ffx test run fuchsia-pkg://fuchsia.com/service-examples-rust#meta/default.cm
When the above command is run, you can see the following output in the test console in addition to the test cases passing:
