Eradicating Non-Determinism in Tests

April 14, 2011 0

Martin Fowler discusses the problem of non-deterministic tests – tests that sometimes pass and sometimes fail. Non-deterministic tests can completely destroy the value of an automated regression suite. This article outlines how to deal with them and presents treatments for the common causes for non-determinism: lack of isolation, asynchronous behavior, remote services, time, and resource leaks.

Unit Testing in Java: Broad Assertion

February 28, 2011 1

Broad assertion cuts out too large a chunk of output and side effects for bit-to-bit comparison, which makes it harmful due to the resulting brittleness. The assertion fails if any small detail changes, regardless of whether that change is relevant to the interests of this particular test. In this article, based on chapter 4 of Unit Testing in Java, author Lasse Koskela explains how to refactor the tests that suffer from broad assertion.
