    Automated unit testing is commonly considered an essential part of writing reliable, bug-free software. But writing automated tests introduces a number of challenges of its own. Naively-written tests are complex, brittle and hard to understand. This increases their cost-of-ownership and reduces the value they provide.

    In this talk, Gerard Meszaros examines some of the key pitfalls and shows us how to improve the quality of our automated tests. He shows us how we can make our tests shorter, clearer and cheaper to prepare by refactoring a long, complex test into a short easy-to-understand test. Then he goes on to show how we can apply the same concepts to writing new tests quickly and cheaply.

    Code that is difficult to understand, hard to modify and challenging to extend is hazardous to developers, users and organizations. Refactoring, or improving the design of existing code, is one of our greatest defenses against such code. In this talk, I’ll discuss the value of refactoring, how we practice it safely, when and why we refactor, the power of refactoring tools and when we avoid refactoring.  I’ll be using several real-world examples of refactoring and sharing what I’ve learned about this important practice of the last 20 years.
