Auto-graded programming assignments may use a Unit test to test small parts of a program. Unlike a Compare output test, which evaluates your program's output for specific input values, a Unit test evaluates individual methods to determines if each method: is named correctly and has the correct parameters and return type • calculates and returns the correct value (or prints the correct output) This example lab uses multiple unit tests to test the kilo ToPounds() function. Complete a program that takes a weight in kilograms as input, converts the weight to pounds, and then outputs the weight in pounds. 1 kilogram = 2.204 pounds (lbs). Ex: If the input is: 10 the output is: 22.040000000000003 lbs Note: Your program must define the method public static double kiloToPounds (double kilos) The program below has an error in the kilo ToPounds() method. 1. Try submitting the program for grading (click "Submit mode", then "Submit for grading"). Notice that the first two test cases fail, but the third test case passes. The first test case fails because the program outputs the result from the kilo ToPounds() function, which has an error. The second test case uses a Unit test to test the kilo ToPounds() function, which fails. 2. Change the kiloToPounds() method to multiply the variable kilos by 2.204, instead of dividing. The return statement should be: return (kilos * 2.204); Submit again. Now the test cases should all pass. Note: A common error is to mistype a function name with the incorrect capitalization. Function names are case sensitive, so if a lab program asks for a kiloToPounds() function, a Kilo ToPounds() function that works for you in develop mode will result in a failed unit test (the unit test will not be able to find kilo ToPounds()).

Transcribed Image Text:Auto-graded programming assignments may use a Unit test to test small parts of a program. Unlike a Compare output test, which evaluates
your program's output for specific input values, a Unit test evaluates individual methods to determines if each method:
is named correctly and has the correct parameters and return type
• calculates and returns the correct value (or prints the correct output)
This example lab uses multiple unit tests to test the kilo ToPounds() function.
Complete a program that takes a weight in kilograms as input, converts the weight to pounds, and then outputs the weight in pounds. 1
kilogram = 2.204 pounds (lbs).
Ex: If the input is:
10
the output is:
22.040000000000003 lbs
Note: Your program must define the method
public static double kiloToPounds (double kilos)
The program below has an error in the kilo ToPounds() method.
1. Try submitting the program for grading (click "Submit mode", then "Submit for grading"). Notice that the first two test cases fail, but
the third test case passes. The first test case fails because the program outputs the result from the kilo ToPounds() function, which
has an error. The second test case uses a Unit test to test the kilo ToPounds() function, which fails.
2. Change the kiloToPounds() method to multiply the variable kilos by 2.204, instead of dividing. The return statement should be: return
(kilos * 2.204); Submit again. Now the test cases should all pass.
Note: A common error is to mistype a function name with the incorrect capitalization. Function names are case sensitive, so if a lab
program asks for a kiloToPounds() function, a Kilo ToPounds() function that works for you in develop mode will result in a failed unit test
(the unit test will not be able to find kilo ToPounds()).
