After add test cases - Jomsaruj/coffeemaker GitHub Wiki

The following JaCoCo test report is generated AFTER add more test cases

As you can see now my unit test cover 100% of instructions and branches for both CoffeeMaker and Inventory class

Here is the list of added test cases

Test ID	Test Case Name	Description	Expected Result	Actual Result	Status
56	testPurchaseEmptyRecipe	involk method makeCoffee with non-exist recipe number and amount of money as parameters	return full amount of money that user input to the system	Same as expected result	pass
57	testSetInventoryToNegative	set all inventory to -1	throws InventoryException	Same as expected result	pass

Optional: I have add 3 more test case for Recipe class. Here is the list of added test cases

Test ID	Test Case Name	Description	Expected Result	Actual Result	Status
58	testCompareDuplicateObject	compare 2 exactly duplicate object	method equal return true	Same as expected result	pass
59	testCompareDifferentObject	compare 2 object that is an instance of different class	method equal return false	Same as expected result	pass
60	testHasCode	test that code of same object is same and code of different object is different	each object has unique code	Same as expected result	pass

It seem impossible to reach 100% coverage for class Recipe because there is a code where they check for null recipe name and it is impossible to set recipe's name as null
