+ * Inputs:

+ *
+ * Steps:
+ * 1) Assign a local variable with the expected value of the define that

+ * 2) Compare the value of the local variable with the value of the
+ *    define.
+ * 3) Return fail if the value of the define does not match with the
+ *    expected value stored in local variable.
+ * 4) Repeat steps 1 - 3 for all the sizes defined in the unit.
+ *
+ * Output:
+ * The test returns PASS if the values of #defines match with the respective
+ * expected value.
+ * The test returns FAIL if there is a mismatch between defined value and
+ * the expected value.
