 @section zunitc_execution Controlling Execution
 
-To control execution, the various zuc_set_* functions can be called before invoking ZUC_RUN_TESTS().

 @subsection zunitc_execution_commandline Commandline Parameters
 
-The current implementation defers processing of command-line parameters to the main application hosting the testing. It is possible that a helper to process certain parameters may be added.

 - '*' matches any number of characters including zero.
 - '?' matches any single character.
 
-Calling zuc_list_tests() after zuc_set_filter() can be done to show the effects of the matching without needing to actually run tests.

 @subsection zunitc_execution_repeat Repeating Tests
 
-Setting the repeat count higher than 1 ( via zuc_set_repeat() ) will cause the tests to be executed several times in a row. This can be useful for stress testing, checking for leaks, etc.

 @subsection zunitc_execution_randomize Randomizing Tests
 
-Test ordering can be randomized by setting a non-zero positive value to zuc_set_random(). Setting it to 1 will cause the framework to pick a random seed based on the time. A value greater than 1 will be taken as a random seed itself. And setting it to 0 will disable randomization and allow the test to be executed in their natural ordering.
