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

Problem

I have been using Vue-cli 3 with Karam. When I add sinon-chai to frameworks in karam.config.js. I got the error "Error: No provider for "framework:sinon-chai"! (Resolving: framework:sinon-chai)".

{
     ...
     frameworks: ['mocha', 'chai', 'sinon-chai'],
     ...
}

Solution

After installing karma-sinon-chai, the error was gone.

yarn add karma-sinon-chai --dev
