first passing test, assert that getPrimeFactors method exists
test 2: tested that getPrimeFactors method returns an array
test 3: assert that getPrimeFactors takes one parameter
committing lastest work:
- asserts that the isPrime is correctly validating a number
- asserts that getPrimeFactors is returning correct array for a prim
- asserts that getLrgestPrime returns the correct integer
For the moment I have just used the array of prime factors for 13195 as I could not get the gmp extension to work locally to solve the problem.
