Dfect 0.1.0

Assertion testing library for Ruby

http://snk.tuxfamily.org...

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 313 lines of code.

Version 0.1.0 (2009-04-28)

This release adds new variations to assertion methods, fixes
several bugs, and improves test coverage.

Thank you

* François Beausoleil contributed patches for both code
and tests! :-)

New features

* Added [1]negation (m!) and [2]sampling (m?) variations to
[3]assertion methods.
These new methods implement assertion functionality
missing so far (previously we could not assert that a
given exception was NOT thrown) and thereby allow us to
fully test Dfect using itself.

* Added documentation on [4]how to insulate tests from the
global Ruby namespace.

Bug fixes

* The E() method did not consider the case where a block
does not raise anything as a failure. --François
Beausoleil

* When creating a report about an assertion failure, an
exception would be thrown if any local variables pointed
to an empty array.

* The Dfect::<() method broke the inheritance-checking
behavior of the < class method.
Added a bypass to the originial behavior so that RCov::XX
can properly generate a report about code that uses
Dfect.

* Added workaround for YAML error when serializing a class
object:
TypeError: can't dump anonymous class Class

Housekeeping

* Filled the big holes in test coverage. Everything except
the runtime debugging logic is now covered by the unit
tests.
