Initialize and reset a test

• Setup a tests suite with the setup() method
• Reset a testing environment with the tearDown() method
• Introduction to fixtures
• Lab: setup and reset a tests suite with setup() and tearDown() methods

Testing exceptions

• Write unit tests for methods, which can handle exceptions
• Testing exception with the setExpectedException() assertion method
• Testing exception by using the @expectedException annotation
• Testing exception thanks to a try { } catch code block
• Lab: implement unit tests for a method that can throw an exception

Test Driven Development
