How to use barreltest and test barrel code on the command-line?

I am looking for guidance on how to test barrel code from the command-line. From the documentation:

Barrels can be compiled and tested via the command line.

barrelbuild

Calls the Monkey C Barrel compiler. Much like monkeyc the barrelbuild call takes code from multiple files to be included in the library (.barrel file). The -f argument is required as the manifest file path is specified in one of the Barrel’s Jungle files. For more info, run barrelbuild without any arguments to see a full list of argument definitions.

> barrelbuild -o <output.barrel> -f <barrel.jungle>

barreltest

Executes Run No Evil tests on the .barrel file. Requires the -d argument with a valid device id.

> barreltest -o <output.barrel> -f <barrel.jungle> -d <device_id>


This suggests that barreltest will run the annotated unit tests within the barrel code. However, barreltest succeeds silently and does not output any test results to the console.

From playing around a bit, I've found that I am able to test the barrel code alongside my main app code by following these steps:

1. Build the barrel with barrelbuild
2. Link to the .barrel file within my main app's jungle and manifest files.
3. Build a PRG file for unit testing.
4. Run Run No Evil on my main app from the command-line.
   1. The unit test results from my main app and the barrel are output normally to the console.

The above steps fail if I instead link my main app to the output file of barreltest. For example:

$ barreltest -o /path/to/main/app/barrels/Barrel-test.barrel -f /path/to/Barrel/monkey.jungle -d <device> -y <key_path>

$ monkeyc -o tmp.prg -f monkey.jungle -d<device> -y <key_path> --unit-test

Other notes:

• The output of barrelbuild appears to be a zip of the barrel code.
• The output of barreltest is some binary.
