+_NOTE: It may not be applicable for every API call_
+
+# 2. Test Firmware Design
+
+The following guidelines are used when writing the C program to be flashed to
+the board.
+
+## 2.1. Test Firmware Declarations
+
+- Tests should interact through a shell
+- Commands should be synchronous
+- Tests should have a `get_metadata` command
+- The `get_metadata` command should contain at least board name, and
+application name
+- Tests should have a `echo <random 8 hex digits>` command
</pre>
<p>Yup, I will try to implement something, I suppose it would be like the ps/reboot/ect. where you can just include it so there will be no code duplication.</p>
