Test and sub-assembly 5.1-5.2

Since the last experiment 5.1 basically completed Phase 1 (encapsulation), Phase 2 (subtraction simple test), so this experiment we focus on the implementation of Phase 3 parameter detection,

Test Cases
Test Project Name	Arithmetic Simple test
Test personnel	Feng Meixin (http://www.cnblogs.com/maxx/) Wu Shu Ting (http://www.cnblogs.com/wst-2015/)	Date of establishment	May 8, 2015
Functional characteristics	Test this arithmetic (parameter)

Black box test:

Number of operators	input type	Input data	Expected output	Actual output	Test status
1	1 Correct values	(4,4,+)	8	8	That's right
2	2 numeric value with illegal characters	(2,32,3w,-,+)	An exception occurred	An exception occurred	That's right
1	3 Subtraction	(16,8,/)	2	2	That's right
1	4 Illegal operators	(2,4,G)	Illegal characters	Illegal characters	That's right
2	5 Division Denominator is 0	(3,1,0,-,/)	Prompt appears	The divisor cannot be 0, the formula is invalid	That's right

White box test:

Number of operators	Test Cases	Use case description	Overridden Code	Test results
2	(2,1,1,-,+)	Input of numeric values	Input (15-50)	Run successfully without failure
1	(3,5,W)	Illegal operator	Input (92-117)	Can judge illegal characters
4	(4,5,1,1,-,*+,-)	Whether to run the algorithm	（）	Run successfully without failure

Because there is urgent, failed to perfect the test case, come back tonight, will be well perfected, hope teacher Haihan!
