TDD Programimng

TDD in Java

This TDD in Java training course is essential for any Java team adopting Agile software development.

  • 2 days hands-on TDD in Java training workshop.
  • Optional day add-on to provide extra time with exercises / to look at code and discuss legacy issues.
  • Free follow on day of hands on coaching with developers on your code base

A test-driven approach, in which design is grown and code delivered incrementally according to functionality or risk, forms the basis of the construction phase of an iterative and incremental development. The use of unit testing provides confidence in existing code and supports the ability to refactor code as development unfolds.

TDD in Java training

This 2-day workshop presents a number of modern practices for developing code based on an adaptive development life cycle. Agility and predictability are two qualities often missing from software development.

The course is intended as a practical course: the best way to appreciate how test-driven development works and what it feels like is to do it in practice, making sense of the principles item bodies. In this form the course is based on lecture material, demonstration, discussion, exercises and hands-on labs.

Who is this course for?

The course is suitable for software developers experienced in Java and familiar with object-oriented principles and practices. Any previous exposure to JUnit or Agile development concepts is beneficial but not essential.

What Will I learn?

  • Appreciate the benefits of testing as a design tool and not just a defect reduction technique.
  • Recognise the purpose and practice of refactoring in keeping a system supple and adaptable.
  • Know how to build up a set of unit tests in JUnit.
  • Understand the consequences of dependency management on testing and code quality.

Topics included

  • Programmer Testing Evidence of care: Testing viewpoint, Pragmatic testing, Automation, Bug pathology, Qualitative and constructive.
  • Good Unit Tests Test quality: Good unit tests (GUTs), Not-so-good unit tests, Fine-grained tests, Behavioural tests, Functional versus operational testing and Black-box tests.
  • Overview of JUnit JUnit and the xUnit family: Test cases in JUnit 3, Test cases in JUnit 4, JUnit assertions, Testing thrown exceptions, Other JUnit features and Organising JUnit tests.
