Agile Technical Practices Distilled

By: Pedro M. Santos, Marco Consolaro, Alessandro Di Gioia

Overview of this book

The number of popular technical practices has grown exponentially in the last few years. Learning the common fundamental software development practices can help you become a better programmer. This book uses the term Agile as a wide umbrella and covers Agile principles and practices, as well as most methodologies associated with it. You’ll begin by discovering how driver-navigator, chess clock, and other techniques used in the pair programming approach introduce discipline while writing code. You’ll then learn to safely change the design of your code using refactoring. While learning these techniques, you’ll also explore various best practices to write efficient tests. The concluding chapters of the book delve deep into the SOLID principles - the five design principles that you can use to make your software more understandable, flexible and maintainable. By the end of the book, you will have discovered new ideas for improving your software design skills, the relationship within your team, and the way your business works.

Great Habits

In this lesson, we introduced a new habit. Check it out on the following list.

Considerations when Writing a New Test

  • Tests should test one thing only.
  • Create more specific tests to drive a more generic solution (triangulate).
  • Give your tests meaningful names (behavior-oriented/goal-oriented names) that reflect your business domain.
  • See that the test fails for the right reason.
  • Ensure you have meaningful feedback from failing tests.
  • Keep your tests and production code separate.
  • Organize your unit tests to reflect your production code (similar project structure).
  • Organize your test in arrange, act, and assert blocks.

– Arrange (also known as Given) all necessary preconditions.

– Act (also known as When) on the subject under test.

– Assert (also known as Then) that the expected results have occurred.

  • Write the assertion first and work backward.

– Write your test by first writing...
