Retrieve CompoundInterestYourLastName (from Topic 3). Create a JUnit Test case to test your method. Write three tests using the data and results below.

A hint: You can give your assertEquals method some leeway so you don't need the exact values by using this method:

assertEquals(double expected, double actual, double delta); Asserts that two doubles or floats are equal to within a positive delta.

If you ran your methods (with the main method without the printf( )), you'll see that you get several decimal points. One way that we can account for small differences is by giving the assertEquals method a delta - 0.01. This means that if the return result is within 0.01 of the expected value, return true. The assertion method would look something like:

assertEquals(expected, actual, 0.01);

Write assertion methods for the three examples below. Make sure that your assertion methods all pass.

System.out.printf("Your total is $%.2f", computeBalance(1000, .045, 3));

// should return $1141.17

System.out.printf(" Your total is $%.2f", computeBalance(2000, .03, 5));

// should return $2318.55

System.out.printf(" Your total is $%.2f", computeBalance(3000, .01, 10));

// should return $3313.87

Pay close attention to your parameters to make sure they match the test data!
