Test code coverage help

I have some code a third party put in with zero test coverage.  I do not know how to write test coverage.  Any ideas?  I need 2% more coverage to meet the minimum of 75%.

April,

Here the class test you can use. Do you know how to execute through the developer console?
  
@isTest(SeeAllData=true)
public class TestMeritIncreaseCalculationUtility {
    
    static testMethod void getNewRate(){
        MeritIncreaseCalculationUtility objTest = new MeritIncreaseCalculationUtility();
        
        //Here you put parameters to cover all situations of the method
        //This test cover 60% of this class
        objTest.getNewRate(0, 6, 20);     
        objTest.getNewRate(4, 2, 50);
    }
}
Please if this help you put like best anwser.
Marcilio.

Would I have to create this on the sandbox then promote via a change set?
