Book description
Develop high-quality and maintainable Python applications using the principles of test-driven development
In Detail
This book starts with a look at the test-driven development process, and how it is different from the traditional way of writing code. All the concepts are presented in the context of a real application that is developed in a step-by-step manner over the course of the book. While exploring the common types of smelly code, we will go back into our example project and clean up the smells that we find.
Additionally, we will use mocking to implement the parts of our example project that depend on other systems. Towards the end of the book, we'll take a look at the most common patterns and anti-patterns associated with test-driven development, including integration of test results into the development process.
What You Will Learn
Implement the test-driven development process in Python applications
Fully leverage Python's powerful built-in unittest and doctest modules
Effectively add features to existing code bases that do not have any tests
Safely resolve problems with the code and design, without breaking any functionality
Utilize Python's powerful mock and patch functionality to test complex interactions
Integrate unit testing into the overall software delivery process
Use doctest to test code with examples
Enhance TDD with the nose2 test runner
