The WHO statement “Testing, Testing Testing!!!” has crucial value in the process of defeating the infection and terminating the SARS-CoV-2 pandemic crises. 
This paper is proposing an effective combination of three imperfect testing methods as a solution for a testing strategy, as a base for emerging coordinated medical, social, economic and politic measures. 

When the vaccine will be available, a massive vaccination will be applied at the populational level. In the absence of vaccination and effective treatment, systematic testing is a decisive condition for success. As none of the testing methods proved themselves as being generally effective and applicable, a combination of them, would amplify the advantages and minimize the disadvantages.   

The rationality is based on empirical assumptions, reasonably accepted.
 
For example:

-    The higher number of people are tested, the more asymptomatic or mild symptomatic infection carriers will be identified.
-    The lower number of infected will produce a lower rate of infections
-    The accuracy of the testing method will influence the effectiveness of diagnosis
-    The number of infected will influence the loading of the medical systems
-    The entire population cannot be tested at the same time
-    The medical system's role is crucial. Could be the problem (source of infection) or the solution (prevention, testing and identifying the infection, treatment)
-    The logistical and economic conditions are determinant.
-    Preserving and enlarging step by step the cleared areas will lead to a cleared society
The description of the testing methods with advantages and disadvantages is scientifically proved and there are numerous related articles published in scientific journals and publications.
