docs: //BeforeSuite blocks are run just once before any specs are run.  When running in parallel, each
  //parallel node process will call BeforeSuite.
  //
  //BeforeSuite blocks can be made asynchronous by providing a body function that accepts a Done channel
  //
  //You may only register *one* BeforeSuite handler per test suite.  You typically do so in your bootstrap file at the top level.
