The Python Apprentice

By: Robert Smallshire, Austin Bingham

Overview of this book

Experienced programmers want to know how to enhance their craft and we want to help them start as apprentices with Python. We know that before mastering Python you need to learn the culture and the tools to become a productive member of any Python project. Our goal with this book is to give you a practical and thorough introduction to Python programming, providing you with the insight and technical craftsmanship you need to be a productive member of any Python project. Python is a big language, and it’s not our intention with this book to cover everything there is to know. We just want to make sure that you, as the developer, know the tools, basic idioms and of course the ins and outs of the language, the standard library and other modules to be able to jump into most projects.

Summary


  • The unittest module is a framework for developing reliable automated tests.
  • You define test cases by subclassing from unittest.TestCase.
  • The unittest.main() function is useful for running all of the tests in a module.
  • The setUp() and tearDown() fixtures are used to run code before and after each test method.
  • Test methods are defined by creating method names that start with test_ on test case objects.
  • The various TestCase.assert... methods can be used to make a test method fail when the right conditions aren't met.
  • Use TestCase.assertRaises() in a with-statement to check that the right exceptions are thrown in a test.
  1. Test-driven development, or simply TDD, is a form of software development where tests are written first, That is, before you write the actual functionality to be tested. This may seem backwards at first, but it can be a surprisingly powerful technique. You can learn more about TDD here.

  2. Note that we don't actually try to test any functionality yet. This is just the initial skeleton...
