Summary

• To make the executable tests run:

  • Add to each executable test:

    - An extends clause that references your application test class

    - A pass-thru constructor

  • Define an application-test class that

    - Is named AppTest, where App is the name of your application

    - Extends JUnit's TestCase

    - Adds a pass-thru constructor

    - Defines assertFalse

    - Defines a method that calls the system code you want to test (requires knowledge of how the code in the system works)

• Compile the executable tests with javac, just as with any other java program.

• Run your tests with java and JUnit's TestRunner utility:

  • The GUI version is junit.swingui.TestRunner.

  • The command-line version is junit.textui.TestRunner.

• Combine all the tests into a test suite in AllTests, so you can run them in a single operation.

We encourage you to try this out yourself in the following exercise and see that it isn't as hard as you might think.
