                        Dfect 1.0.0

            Assertion testing library for Ruby

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

```

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

Dfect is exciting because:

```
 * It has only 5 methods to remember: D F E C T.

 * It lets you debug assertion failures interactively.

 * It keeps a detailed report of assertion failures.

 * It lets you nest tests and execution hooks.

 * It is implemented in a mere 479 lines of code.

```

Version 1.0.0 (2009-05-03)

This release improves default choices, adds emulation layers  
to mimic other testing libraries, and fixes some bugs.

Incompatible changes

```
 * The :debug option is now enabled by default and is no
   longer linked to the value of $DEBUG.

 * Dfect.run() now appends to previous results by default.
   This behavior can be disabled by passing false to the
   method.

```

New features

```
 * Add emulation layers to mimic other testing libraries:
      + dfect/unit -- Test::Unit
      + dfect/mini -- Minitest
      + dfect/spec -- RSpec

```

Bug fixes

```
 * Do not blindly replace Class#to_yaml; it might be fixed
   someday.

```

Housekeeping

```
 * Add [1]Motivation section in user manual to promote
   interactive debugging.

 * Add brief [2]History of this project's inception.

 * Remove redundant assertions for F!() and T!() methods in
   test suite.

 * Add copyright notice at the top of every file.

```
