This directory contains a simple example using program arguments and environment variables in Component Framework.
Use ffx component run to launch this component into a restricted realm for development purposes:
tools/ffx component run fuchsia-pkg://fuchsiasamples.com/echo-example#meta/echo.cm
When the above command is run, you can see the following output with ffx log:
[echo] INFO: Hello, Alice, Bob, Spot!
Unit tests for echo are available in the echo-unittests package. Use the ffx test run command to run the tests on a target device:
$ tools/ffx test run fuchsia-pkg://fuchsiasamples.com/echo_unittests#meta/echo_unittests.cm
You should see each of the unit tests execute and pass:
