Writing a Comprehensive Unit Test

A common theme amongst people professing “best practices” for unit tests is that you should only write a single assertion for each test. People who make these proclamations rarely show any unit test and those that do only show one. Yet this pattern may require a dozen other unit tests to ensure quality for even a trivial operation. This article uses examples to question that recommendation.

Rajneesh Namta shares the lessons he’s learned while automating software tests on a recent Agile project.

The Limits of Agile

The problems faced by teams that are attempting Agile in non-traditional settings aren't that Agile principles are inapplicable, nor that the feedback cycle is doomed to failure; but rather, outside of a certain Agile sweet-spot there are additional barriers and costs to applying Agile techniques. None of these obstacles prevents Agile in itself but each increases the cost of getting to Agile.
