Difference between Karma and Mocha
Imagine the following scenario:
Write your own test suites with
Mocha
Use
Karma
to run programmatically yourMocha
tests cross-browser and cross-devicesMore, integrate
Karma
with your Jasmine existing environmentEven more, integrate
Karma
in your Continuous Integration cycleUse a million
Karma
plugin to check coverage, complexity, framework stuff, etc...
The power of Karma
is that it can spawn real browsers - such Chrome or Firefox - to effectively test your code with them.
With Mocha
you can run it in a NodeJS
environment or in a webpage.

I am new to the Javascript world, being majorly into OOP. I have tried to look up online for a clear cut distinction between Karma and Mocha but in vain. I know Karma is a Test Runner and Mocha is a unit testing Framework, but Mocha also has its own driver and can be used for running tests in the browser. That said, I don't understand what Karma brings to the plate, and why are people using these in conjunction.

Harry Moreno almost 9 yearsTo be fair though, you can run mocha in multiple browsers to get the cross-browser effect you list. Karma really shines as a test runner, continuous integration, retesting on file change, ability to use in conjunction with jasmine/qunit, etc
