Compound interest Calculation--unit test

Scenario analysis, expected return values, and the following table of running results:

notes: Expected results 0.0 , which indicates that the input data is incorrect. That's not getting the right results.

Test module	Test input	Expected results	Run results	Bug tracking
Compound Interest Calculation	(100,10,0.03)	134.39	That's right
Simple Interest Calculation	(100,10,0.03)	130.0	That's right
Calculate Pre-Investment principal	(100,10,0.03)	76.92	That's right
Calculate how many years after doubling	(100,200,0.03)	23.44	That's right
Calculate interest rate	(100,200,10)	0.073	That's right
Fixed by year	(100,10,0.03)	1180.77	That's right
Monthly voting	(100,10,0.03)	14169.35	That's right
Monthly principal and interest	(100,10,0.03)	1.11	That's right
