UPD: it seems that zlib 1.2.11 really changed deflate stored binary representation

const pako    = require('pako');
const zlib    = require('zlib');
const fs      = require('fs');
const assert  = require('assert');
const join    = require('path').join;


const len100k = new Uint8Array(fs.readFileSync(join(__dirname, 'fixtures/lorem_en_100k.txt')));


describe('deflate level 0 checks', function () {

  it('pako deflate -> pako inflate', function () {
    assert.deepEqual(
      pako.inflate(pako.deflate(len100k, { level: 0 })),
      len100k
    );
  });

  it('zlib deflate -> zlib inflate', function () {
    assert.deepEqual(
      zlib.inflateSync(zlib.deflateSync(Buffer.from(len100k), { level: 0 })),
      len100k
    );
  });

  it('zlib deflate -> pako inflate', function () {
    assert.deepEqual(
      pako.inflate(zlib.deflateSync(Buffer.from(len100k), { level: 0 })),
      len100k
    );
  });

  it('zlib deflate vs pako deflate', function () {
    assert.deepEqual(
      zlib.deflateSync(Buffer.from(len100k), { level: 0 }),
      pako.deflate(len100k, { level: 0 })
    );
  });

});

Uh oh!

Fix broken tests { level: 0 } #107
