Testing is crucial in Software Development for preventing bugs, reducing costs, and boosting performance. This course covers essential methods like Test Driven Development (TDD) and Behavior Driven Development (BDD), with TDD focusing on individual code units and BDD on how these units integrate.

You’ll learn the fundamentals of TDD and BDD, including automated testing’s role in creating resilient applications. Explore testing basics such as test cases, levels, release cycles, and popular tools.

Through real-world inspired labs, you’ll gain hands-on experience with TDD and BDD. Develop TDD test cases with assertions and fixtures using the Nose testing package, and apply advanced techniques like code coverage, fake data, and mock objects. Set up a BDD environment with Behave, write feature and step files, and test web interfaces with Selenium.

By the end, you'll have the skills to effectively perform TDD and BDD, and understand when to use these methodologies for optimal development outcomes.
