Testing the Contract Metaphor A contract represents a service agreement between two parties, the bounded provision of service by one party to the other.

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?

Is ''Agile'' Distracting You? If a process tool or service claims to be agile it must be good, right? Not necessarily. The term "agile" has become abused and, since we don't have a standard dictionary definition, it is open to interpretation. So, let's look beyond the label to what really matters—value. |
