                          Detest

            Assertion testing library for Ruby

           http://snk.tuxfamily.org/lib/detest/

```

Detest is an assertion testing library for Ruby that  
emphasizes a simple assertion vocabulary, instant  
debuggability of failures, and flexibility in composing  
tests.

Version 3.1.0 (2010-07-25)

This release adds N() methods for nil value assertions and  
renames the project from “DIFECTS” to “Detest” to avoid  
forming a habit of intentional misspellings.

New features:

```
 * Add N(), N!(), and N?() methods for asserting that a
   value is nil. This idea comes from Gavin S.'s
   [1]Attest assertion testing library.

```

Housekeeping:

```
 * Rename project from "DIFECTS" to "Detest".

 * Upgrade project to Inochi 4.0.0 infrastructure.

 * Minor code refactoring and manual revisions.

```
