That's No Reason to Automate!

Automating test execution is supposed to give tremendous benefits, but often gives disappointing results—because it hasn’t met the objectives set for it. The fault may not lie with the automation itself, but with the objectives you are attempting to achieve. Aiming at the wrong target does not bring success! For example, objectives for automation are often confused with objectives for testing, but they should be different. In this article, learn how to avoid the most insidious traps and how to recognize good objectives for automation.

Testing the Contract Metaphor

A contract represents a service agreement between two parties, the bounded provision of service by one party to the other. This metaphor also applies to how we can think about the relationship between unit tests and code. A contractual mindset encourages test names and partitioning based on clear propositions, backed up with executable examples.

Issues about Metrics about Bugs

Managers often use metrics to help make decisions about the state of the product or the quality of the work done by the test group. Yet, measurements derived from bug counts can be highly misleading because a "bug" isn't a tangible, countable thing; it's a label for some aspect of some relationship between some person and some product, and it's influenced by when and how we count ... and who is doing the counting.

GUT Instinct

Whether or not a unit test is considered good is not simply about what it tests: It is also very much about "how" it tests. Is the test readable and maintainable? Does it define the expected behavior or merely assume it? To be sustainable, the style of a unit test is just as important as the style of any other code. Perhaps a little surprisingly, the most commonly favored test partitioning style does not meet these expectations.

The Trouble with Derivation

This article discusses the dark underbelly of derivation: the fragile base class. It's possible to modify a base class in such a way that, even though you've improved its implementation and all your tests work just fine, you've nonetheless damaged the derived classes, perhaps fatally.

Resistance Is Futile

Why do so many people resist change, even when that change will be for the better? It's simple, really. Every change ends something, and endings mean loss. People don't like loss. Even the best changes mean something familiar will end.
