About this course

Skip About this course

Testing is one of the most critical processes of the Software Development Lifecycle (SDLC) and often contributes to preventing bugs, reducing development costs, and improving performance. Two of the best methods for testing software are Test Driven Development (TDD) and Behavior Driven Development (BDD). TDD tests individual units of code while BDD tests how these units work together.

This course introduces you to the fundamentals of both TDD and BDD, You’ll discover what automated testing is and why it is essential for building robust applications resilient to failure. You'll explore the basics of testing, including test cases, testing levels, the traditional release cycle, and the benefits, concepts and popular tools involved.

This course provides multiple real-world inspired hands-on labs to demonstrate your skills with TDD and BDD. You’ll create TDD test cases by writing test assertions and building test fixtures, and you’ll run these test cases using the Nose testing package. You’ll practice more advanced TDD methods, such as increasing code coverage, generating and using fake data, and testing mock objects. You’ll also practice setting up a BDD environment using Behave, write the feature and step files, test a web interface using Selenium, and load sample data for testing.

By the end of the course you will have the knowledge and skills to perform test driven development (TDD) and behavior driven development (BDD) testing and understand when to apply these development techniques.
