Description
Objective
In this lab, you will explore managing a system of software with test suites via JUnit and build
management with Make.
Working alone or in a group of 2, you will apply your knowledge of JUnit and Makefiles to write
a test script for the newest release of the HfxDonairExpress online ordering system, to improve their
build automation, and to include your test cases in their existing testing setup.
Preparation
• Download and install GNU Make. You can alternatively use it on timberlea.
Procedure
Set-up
1. Download and unzip the source directory posted on Brightspace.
Lab steps
Part 1 – Unit Testing Write a JUnit test suite for HfxDonairExpress, with one test method
for each of the following cases. You should put these test cases in a file called UnitTests.java. Your
test cases should check that the method in question (either order or makeOrder) returns the correct
value.
1. order method: Ordering a small donair
2. order method: Ordering a large donair with the coupon code “YOLO5”
3. order method: Ordering a medium pizza with pepperoni and mushrooms
4. makeOrder method: Making 1 order
5. makeOrder method: Making 2 orders in a row

Part 2 – Understanding Makefiles Answer the following questions about the provided Makefile:
1. Which file(s) are included in the SRC variable?
2. What file(s) does the all target depend on?
3. What is the command used to make the hfxdonairexpress.jar file?
4. What does the test target do? You may want to try running the command make test to see.
Part 3 – Writing Makefiles Add the following features to the existing Makefile:
1. Modify the Makefile so that your unit test class is compiled and included in hfxdonairexpress.jar
2. Modify the Makefile to put the compiled .html documentation files into a new sub-directory,
docs
3. Modify the Makefile to include a target clean which deletes the compiled .class and .html
files. Note: the rm command can be used to delete a file
Questions
1. Why is it important to have a portable, reproducible build system that isn’t tied to a particular
IDE?
2. How often should you run a class’ test suite when developing a software system? Explain.
3. Can you see any reason to split test cases up into separate files, or should you just include all of
your test cases for every class in the same file?
Reporting
1. In one file, list
• The members of your team.
• The answers to the questions in part 2.
• The answers to the Questions section of the lab.
2. Generate a PDF from the document.
3. Submit the PDF, UnitTests.java, and you modified Makefile in Brightspace in the Lab/Lab
6 folder.
Assessment
The assessment will be on a letter grade and will reflect how well you have used JUnit and Make,
as well as how your answers to the broadening questions demonstrate that you have thought through
how unit tests and build automation can help you in maintaining and deploying a complicated piece
of software.
