when piped through

Write a Buffer to a transform stream or a sequence of transform streams, then delegate to another assertion using the last stream as the subject.

It's intended to be used with the to yield output satisfying assertion:

return expect(

Buffer.from([

0x1f,

0x8b,

0x08,

0x00,

0x03,

0x63,

0x60,

0x04,

0x00,

0x69,

0x22,

0xde,

0x36,

0x02,

0x00,

]),

'when piped through',

require('zlib').Gunzip(),

'to yield output satisfying',

Buffer.from([0x00, 0x01])

);

Example with multiple transform streams:

return expect(

Buffer.from('yadda'),

'when piped through',

[require('zlib').Gzip(), require('zlib').Gunzip()],

'to yield output satisfying',

Buffer.from('yaddayadda')

);

expected Buffer.from([0x79, 0x61, 0x64, 0x64, 0x61])

when piped through [ Gzip, Gunzip ] to yield output satisfying Buffer.from([0x79, 0x61, 0x64, 0x64, 0x61, 0x79, 0x61, 0x64, 0x64, 0x61])

expected Gunzip

to yield output satisfying Buffer.from([0x79, 0x61, 0x64, 0x64, 0x61, 0x79, 0x61, 0x64, 0x64, 0x61])

expected Buffer.from([0x79, 0x61, 0x64, 0x64, 0x61])

to equal Buffer.from([0x79, 0x61, 0x64, 0x64, 0x61, 0x79, 0x61, 0x64, 0x64, 0x61])
