mocha server test line numbers are wrong

[atomfried]

Hi there,

mocha reports wrong line numbers in server tests with the bellow configuration. I tried adding

retainLines: true

to the transpileServer function but it doesn't work yet...

Seeing the same thing. For example, I get this error at the end of mocha:unit...

1. "after all" hook:
   TypeError: Cannot read property 'on' of undefined
   at Context. (mocha.global.js:12:17)

And mocha.global.js only has 7 lines. In this case, it's referring to line 5 but reporting 12. My guess is that it's line 12 after it's been transpiled.

Bit of a chore to debug mocha tests.

Same here -- inserting a "retainLines":true option into the .babelrc file seems to have solved it for me.

@briankeane That fixed my issue. I didn't even realize our mocha setup was using babel, thank you!
