What is Karma?
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.
Karma is a tool in the Browser Testing category of a tech stack.
Karma is an open source tool with 12K GitHub stars and 1.7K GitHub forks. Here’s a link to Karma's open source repository on GitHub

Protractor or Cypress for ionic-angular?
We have a huge ionic-angular app with almost 100 pages and 10+ injectables. There are no tests written yet. Before we start, we need some suggestions about the framework. Would you suggest Cypress or Angular's Protractor with Jasmine / Karma for a heavy ionic app with Angular?

Karma Alternatives & Comparisons
What are some alternatives to Karma?
Jasmine
Jasmine is a Behavior Driven Development testing framework for JavaScript. It does not rely on browsers, DOM, or any JavaScript framework. Thus it's suited for websites, Node.js projects, or anywhere that JavaScript can run.
Jest
Jest provides you with multiple layers on top of Jasmine.
Mocha
Mocha is a feature-rich JavaScript test framework running on node.js and the browser, making asynchronous testing simple and fun. Mocha tests run serially, allowing for flexible and accurate reporting, while mapping uncaught exceptions to the correct test cases.
Protractor
Protractor is an end-to-end test framework for Angular and AngularJS applications. Protractor runs tests against your application running in a real browser, interacting with it as a user would.
Git
Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.
