Retrieve WidgetOrderYourLastName (from Topic 3). Create a JUnit Test case to test your method. Write three tests using the data and results below (note that you will need to come up with one of your own tests, as only two are provided).

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( ) or DecimalFormat), 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);

Create a JUnit test case to test your newly created method. Use the test data below to confirm you are receiving the correct values.
