Error after install mocha in meteor - meteor

Question

I want to make some test to my software, so I follow some tutorial on the internet and find out the package practicalmeteor:mocha. But after install the package and open the local(without writing any test). I receive the error yelling:

I am using meteor 1.6.1.1

Answer 1

I will put this as an answer because it may still be relevant so new users that came to the same point.
practialmeteor:mocha is a recommended package but not compatible anymore with Meteor >=1.6.1 and the chance is very high that it is not maintained anymore (as you can see on their open gh issues).
Alternative packages include
cultofcoders:mocha
meteortesting:mocha

Answer 2

I've also met such thing so that it really took me some time to figure out.
According to the Meteor Todo App with Angular tutorial, practicalmeteor:mocha package is recommended. And what an interesting thing is that meteortesting:mocha is used in a typical scaffold project.
"scripts": {
"start": "meteor run",
"test": "meteor test --once --driver-package meteortesting:mocha",
"test-app": "TEST_WATCH=1 meteor test --full-app --driver-package meteortesting:mocha",
"visualize": "meteor --production --extra-packages bundle-visualizer"
},
However, only using cultofcoders:mocha which is forked from practicalmeteor:mocha did work.
meteor remove practicalmeteor:mocha
meteor add cultofcoders:mocha
meteor test --driver-package cultofcoders:mocha
Enjoy coding!
