-Title: Random Number Generator APIs
-
-Description:
-
-This test verifies the following random number APIs operate
-as expected:
-sys_rand32_get()
-
---------------------------------------------------------------------------------
-
-Building and Running Project:
-
-This microkernel project outputs to the console.  It can be built and executed
-on QEMU as follows:
-
-    make pristine
-    make qemu
-
---------------------------------------------------------------------------------
-
-Sample Output:
-
-Starting random number tests
-===================================================================
-Generating random numbers
-Generated 10 values with expected randomness
-===================================================================
-PASS - RegressionTaskEntry.
-===================================================================
-PROJECT EXECUTION SUCCESSFUL
