 == Tests
 
+'''Test case functionality:''' Test hardware and software requirements, test if sample code return value on the desirable range.
 
+'''Test case setup:'''
 
+* Check if one or more compatible GPU is present
+* Check if GPU driver is compatible
+* Run sample and test returned value
+
+'''Test case verification value:''' 
+  
+* Return logical value pointing if requirements are present.
+* Return float relative error from expected sample value. This value must be smaller than 0.1%.
+
+'''Status of the test case as for now:''' Not developed yet.
+
+'''Expected characteristics:'''
+
+a) When the option is not activated, the code should pass all the set test and should not display any difference in results nor computational performance.
+
+b) When the option is enabled, a system test must be performed to check if the system fulfills the minimum hardware requirement, there will be some differences that should be appreciable:
+
+  The implementation will reduce run time and have a small increase in memory fingerprint. The impact is expected to make the time of execution of the ported diagnostics routines negligible compared to the non GPU ported case.
+
+  The diagnostics results won't be bit-to-bit identical to CPU-only implementation runs or in other hardware but will be reproducible in the same hardware and stack software.
+
+  The ported diagnostic results will be dependent on float point implementation of the GPU hardware and software. There will be no change in other NEMO subroutines.
