when piped through

Write a string 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(

'foobarquux',

'when piped through',

require('zlib').Gzip(),

'to yield output satisfying',

'to have length',

);

Example with multiple transform streams:

return expect(

'How about that',

'when piped through',

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

'to yield output satisfying',

'when decoded as',

'utf-8',

'not to contain',

'about'

);

expected 'How about that'

when piped through [ Gzip, Gunzip ] to yield output satisfying when decoded as 'utf-8' not to contain 'about'

expected Gunzip

to yield output satisfying when decoded as 'utf-8' not to contain 'about'

expected Buffer.from([0x48, 0x6F, 0x77, 0x20, 0x61, 0x62, 0x6F, 0x75, 0x74, 0x20, 0x74, 0x68, 0x61, 0x74])

when decoded as 'utf-8' not to contain 'about'

How about that
