Test::Bits - Provides a bits_is() subroutine for testing binary data
use Test::Bits; bits_is( $binary_data, [ 0b0010101, 0b01111100 ], 'binary data contains expected values' );
This module 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 Note that the bytes are numbered starting from 0 in the diagnostic output.
The "bits_is()" subroutine takes two required arguments and an optional test name. The first argument should be a plain scalar containing binary data. If it contains any UTF-8 characters an error will be thrown. The second argument should be an array reference of numbers from 0-255 representing the expected value of each byte in the first argument. This allows you write the numbers out in binary format (0bXXXXXXXX) for test cases if you wish to.
