Please run following code on your machine:

import getos from 'getos';
import os from 'os';

getos((e, os) => {
  console.log(
     {
        platform: os.platform(),
        arch: os.arch(),
        version: '3.6.5',
        os,
      }
  );
});

Don't forget to install required packages:

npm install os getos

The problem somewhere in https://github.com/nodkz/mongodb-memory-server/blob/master/src/util/MongoBinaryDownloadUrl.js it does not understand params provided from the code above.

It quite simple to fix, just look at tests https://github.com/nodkz/mongodb-memory-server/blob/master/src/util/__tests__/MongoBinaryDownloadUrl-test.js and add your test case for Win 10. With your PR with broken test helps me to fix code.

PS. How I understand Win 10 uses should get such link 'http://downloads.mongodb.org/win32/mongodb-win32-x86_64-2008plus-ssl-3.6.5.zip'

Sorry for my late reply. It work with this code:

import getos from 'getos';
import os from 'os';


console.log(
    {
    platform: os.platform(),
    arch: os.arch(),
    version: '3.6.5',
    os,
    }
);

And here is the result:

{ platform: 'win32',
  arch: 'x64',
  version: '3.6.5',
  os:
   { arch: { [Function: arch] [Symbol(Symbol.toPrimitive)]: [Function] },
     cpus: [Function: cpus],
     EOL: '\r\n',
     endianness: { [Function: endianness] [Symbol(Symbol.toPrimitive)]: [Function] },
     freemem: { [Function: getFreeMem] [Symbol(Symbol.toPrimitive)]: [Function] },
     homedir: { [Function: getHomeDirectory] [Symbol(Symbol.toPrimitive)]: [Function] },
     hostname: { [Function: getHostname] [Symbol(Symbol.toPrimitive)]: [Function] },
     loadavg: [Function: loadavg],
     networkInterfaces: [Function: networkInterfaces],
     platform: { [Function: platform] [Symbol(Symbol.toPrimitive)]: [Function] },
     release: { [Function: getOSRelease] [Symbol(Symbol.toPrimitive)]: [Function] },
     tmpdir: { [Function: tmpdir] [Symbol(Symbol.toPrimitive)]: [Function] },
     totalmem: { [Function: getTotalMem] [Symbol(Symbol.toPrimitive)]: [Function] },
     type: { [Function: getOSType] [Symbol(Symbol.toPrimitive)]: [Function] },
     userInfo: [Function: getUserInfo],
     uptime: { [Function: getUptime] [Symbol(Symbol.toPrimitive)]: [Function] },
     getNetworkInterfaces: [Function: deprecated],
     tmpDir: [Function: deprecated],
     constants: { UV_UDP_REUSEADDR: 4, errno: [Object], signals: [Object] } } }

It failed on my machine when run the test.

It looks like you have weak internet connection speed.
Try to increase jasmine.DEFAULT_TIMEOUT_INTERVAL = 60000; timeout for the first binaries download.

[nodkz]

Try new 1.8.0 version on your Win machine.

It will automatically download latest MongoDB version on package install.
I think that for the majority of users it will remove the timeout problem for the first test run.
