In this lab, you will explore managing a system of software with test suites via JUnit and build management with Make.
, 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.
