Test Driven Development in Java Training Course

1 . Agile Development Microprocess

• Traditional versus agile development processes
• Iterative and incremental development
• Informal and continuous design
• The role of refactoring
• Refactoring versus other code changes
• Extreme Programming
• Test-Driven Development

2 . Testing in Principle

• Traditional view and reality of testing
• Driving development through testing
• Testing early, often and automatically
• Testing versus debugging
• White-box versus black-box testing
• Functional versus operational testing

3 . Basic Unit Testing in Practice

• Test plans versus test code
• Use of Assert
• Testing at the interface
• Testing the simplest things first
• Testing incrementally
• Testing correctness of failure

4 . Overview of JUnit

• JUnit and the xUnit family
• Test cases, test suites and test runners
• Essential structure of the framework
• Assertion methods
• Testing correctness of exceptions
• Defining common fixture code
• JUnit pattern usage
• Extensions to JUnit

5 . Test-Writing Techniques

• Red, green, refactor
• None to one to many
• Faking it
• Telling the truth
• Isolated and short tests
• Refactor common fixture code
• Declare, prepare, assert
• Test by method, state or scenario
• Custom assertions
• Compile-time constraints
• Running all tests

6 . Common Refactorings

• Renaming variables, methods, classes and packages
• Restructuring class hierarchies by extracting interfaces, superclasses and subclasses
• Partitioning classes by extracting classes and methods
• Changing private representation

7 . Decoupling Techniques

• Unmanaged dependencies
• Test-driven decoupling
• Layering
• Reorganising packages
• Eliminating cyclic dependencies
• Mock objects
• Eliminating Singletons, statics and other globals
• Testing I/O
