Duration: 4 Days
JUnit and other testing frameworks based on JUnit such as Cactus, make it possible to write higher-quality Java code. It is a powerful tool designed to support robust, predictable, and automated testing development in the Java enterprise application arena.
In this comprehnsive hands-on Test-Driven Development(TDD)/JUnit training course, developers will get up and running with essential test-driven development programming skills using JUnit and various open-source testing frameworks. Using test-driven development techniques, you will learn the best practices for writing great programs in Java and cover essential TDD topics and skills.
What You Will Learn
- JUnit
- Use the JUnit Test Runner interface
- JUnit to drive the implementation of Java code
- Test applications using native IDE support
- Best practices and patterns for test development
- JUnit's strengths and weaknesses
- Role of debugging when done in conjunction with tests
- Fundamentals of the TDD using Java and its importance, uses, strengths, and weaknesses
- Basics of JUnit, Cactus, and other testing frameworks and how they relate to TDD
- Better control the development and quality of Java code
- How JUnit affects your perspective on development and increases your focus on a task
- JUnit coding style
- Create well structured JUnit programs
- Compile and execute programs using JUnit, Cactus, StrutsTestCase, and DBUnit using the IDE of your choice
- JUnit testing used for either state-based or interaction-based testing
- Extend testing with mock objects using EasyMock
- Refactoring techniques available to make code as reusable/robust as possible
- Testing techniques
