same result with mocha --require ./server.babel.js --require babel-polyfill --compilers js:babel-register ./test/checklist.js

tried run dummy test mocha ./test/del-me.js:

class Test {
  static createSession(...args) {
    console.log(args);
  }
}

describe('Main workflow', () => {
  Test.createSession(1, 2, 3)
});

works fine

works correct only on node@7

solved by adding:

"ignore": false,

to babel config

Could this be a real issue after all? selenium-webdriver claims to support Node 4 and up, yet it is using rest parameters which isn't supported by default in Node 4 and 5 (if I'm not mistaken). I'm getting errors in Node v4 and v5 (but not v6 and v7) when running a jest test with selenium-webdriver 3.0.1:

 SyntaxError: Unexpected token ...
      
      at transformAndBuildScript (node_modules/jest/node_modules/jest-cli/node_modules/jest-runtime/build/transform.js:320:12)

      at Object.<anonymous> (node_modules/selenium-webdriver/firefox/index.js:119:12)

I believe this is coming from

selenium/javascript/node/selenium-webdriver/lib/http.js

Line 161 in d943ee2

function toExecuteAtomCommand(command, atom, ...params) {

It looks like Node 4 and 5 do support rest parameters, but only with the --harmony flag.

As of 3.0, selenium-webdriver requires node 6.9 or newer.

I see. I just re-read the docs, and even though they are a little confusing it's stated that LTS (6.9.1) and stable (7 something) are the only supported versions. Makes sense, thanks for clarifying @jleyba!
