it('--https --cacert --pfx --key --cert --pfx-passphrase', (done) => {

We don't need this test. Also, has it always been the case that the CLI can run with unknown args?

[hiroppy]

We always accept any args like this.

$ npm run webpack-dev-server -- -a

> [email protected] webpack-dev-server /Users/hiroppy/webpack/webpack-dev-server
> node examples/run-example.js "-a"

And this test is poor.
