DataDiff 1.1.5

It can handle sequence types (lists, tuples, etc), sets, and dictionaries.

When applicable, data dictionaries and sequences will be diffed recursively.

It has special-case handling for multi-line strings, showing them as a typical unified diff.

Nose assertions drop-in replacements are available.

If the assertion fails, a nice data diff is shown, letting you easily pinpoint the root difference.
