The ExecTest class runs a program, defined in the execName variable, on the system where the test is running.

 * The ExecTest class runs a program, defined in the execName variable,

 * The test verdict is set to PASS if the program return code is 0.
 * The test verdict is set to FAIL if the program doesn't execute or 
 * if the program return code is non-zero
 * In this sample, the program is perl.exe.
