Testing TypeScript with Mocha

mocha_testing.ts

/**
  
  This describe blocks will be executed sequentially

  A very important thing to keep in mind when testing with Mocha is, as always, 
  the async nature of JavaScript. Everything inside a describe/it Mocha block 
  will be executed synchroneously, but the results of everything outside them 
  is not guaranteed to be executed sequentially with the rest of the **it** 
  blocks. Therefore, everything should be inside an "it" block if possible.
