How to use sinon on karma?

Question

I'm trying to use karma, chai and sinon to test spy.

1. I did:

   npm install karma-sinon --save-dev
   

2. I added:

   frameworks: ['mocha','chai','chai-sinon']
   

3. I run:

   karma start
   

But I'm getting this error:

Error: No provider for "framework:chai-sinon"! (Resolving: framework:chai-sinon)

Answer 1

I had the same problem by simply adding the chai entry to the Frameworks section of my karma.conf.js script did not solve the problem. Following this Github Issue I found that you need to install the karma-cli globally, and everything else can be local and work.

 npm install --save-dev karma
 npm install -g karma-cli
 npm install --save-dev karma-phantomjs-launcher karma-chai karma-sinon
