Codecov vs Karma: What are the differences?

What is Codecov? Hosted coverage reports with awesome features to enhance your CI workflow. Our patrons rave about our elegant coverage reports, integrated pull request comments, interactive commit graphs, our Chrome plugin and security.

What is Karma? Spectacular Test Runner for JavaScript. Karma is not a testing framework, nor an assertion library. Karma just launches a HTTP server, and generates the test runner HTML file you probably already know from your favourite testing framework. So for testing purposes you can use pretty much anything you like.

Codecov and Karma are primarily classified as "Code Coverage" and "Browser Testing" tools respectively.

Some of the features offered by Codecov are:

  • Beautiful Reports
  • Pull Request Comments
  • Interactive Commit Graphs

On the other hand, Karma provides the following key features:

  • Test on Real Devices
  • Remote Control
  • Testing Framework Agnostic

"More stable than coveralls" is the primary reason why developers consider Codecov over the competitors, whereas "Test Runner" was stated as the key factor in picking Karma.

Karma is an open source tool with 10.7K GitHub stars and 1.61K GitHub forks. Here's a link to Karma's open source repository on GitHub.

Typeform, Sellsuki, and Coderus are some of the popular companies that use Karma, whereas Codecov is used by Repro, ContentSquare, and homezen. Karma has a broader approval, being mentioned in 119 company stacks & 57 developers stacks; compared to Codecov, which is listed in 49 company stacks and 29 developer stacks.

Advice on Karma, Codecov

Felipe
Felipe

May 24, 2020

Needs advice

My website is brand new and one of the few requirements of testings I had to implement was code coverage. Never though it was so hard to implement using a #docker container.
Given my lack of experience, every attempt I tried on making a simple code coverage test using the 4 combinations of #TravisCI, #CircleCi with #Coveralls, #Codecov I failed. The main problem was I was generating the .coverage file within the docker container and couldn't access it with #TravisCi or #CircleCi, every attempt to solve this problem seems to be very hacky and this was not the kind of complexity I want to introduce to my newborn website.
This problem was solved using a specific action for #GitHubActions, it was a 3 line solution I had to put in my github workflow file and I was able to access the .coverage file from my docker container and get the coverage report with #Codecov.
