Mocha test fails with error from “before all” hook

Question

From what I understand, the mocha test framework will throw this error if some error occurs in the before method:

> $(npm bin)/mocha test/*.j         


        

Answer 1

As I was posting this question, I stumbled on this bug which led me to the discovery that I need to make a call to this.enableTimeouts(false) in the beginning of the before function, like so:

let server
before(function(done) {
  this.enableTimeouts(false)  <----
  server = require('../app')
  server.initialize()
    .then(() => {
      console.info('listening on', process.env.PORT)
      server.listen(process.env.PORT, done)
    })
    .catch(err => {
      console.log(err)
      done(err)
    })
})

Hopefully this helps someone else a few hours of debugging.
