Perl module for testing binary data

Test::Bits provides a single subroutine, bits_is(), for testing binary data.

This module is quite similar to Test::BinaryData and Test::HexString in concept. The difference is that this module shows failure diagnostics in a different way, and has a slightly different calling style. Depending on the nature of the data you're working with, this module may be easier to work with.

In particular, when you're doing a lot of bit twiddling, this module's diagnostic output may make it easier to diagnose failures. A typical failure diagnostic will look like this:

The two pieces of binary data are not the same length (got 2, expected 3).

Binary data begins differing at byte 1.

Got: 01111000

Expect: 01111001
