Unit test of compound interest calculation

Test module	Test input	Expected results	Run results
Calculate Principal	(Final value F, age n, interest rate i)	Principal P
1	(3000000,0.03,10)	2232281	√
2	(230000,0.05,30)	53216	√
Calculation life	(final value F, principal p, interest rate i)	Duration N
1	(2000000, 1000000, 0.1)	8	√
2	(20000,3000,0.1)	20	√
Calculate annual interest rate	(final value F, principal p, age n)	Annual Interest Rate I
1	(2000000,1000000,10)	0.072	√
2	(300000,25000,10)	0.282	√

Test scenario: Calculate principal, age, annual interest rate

Expected return value:

Principal: 2232281 actual value: 2232281.75 allowable Error: 1.0

Annual interest Rate: 0.072 actual value: 0,072 allowable error: 0.005

Test results:

Description: I don't know how to do it because I just touched the unit test. The input range for the storage life and the annual interest rate is not unit tested and is controlled only in the source program.
