Karma vs Selenium: What are the differences?

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; Selenium: Web Browser Automation. Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily, it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should!) also be automated as well.

Karma and Selenium can be categorized as "Browser Testing" tools.

"Test Runner" is the primary reason why developers consider Karma over the competitors, whereas "Automates browsers" was stated as the key factor in picking Selenium.

Karma and Selenium are both open source tools. It seems that Selenium with 14.9K GitHub stars and 4.97K forks on GitHub has more adoption than Karma with 10.7K GitHub stars and 1.61K GitHub forks.

According to the StackShare community, Selenium has a broader approval, being mentioned in 776 company stacks & 440 developers stacks; compared to Karma, which is listed in 119 company stacks and 57 developer stacks.

        가장 강력한 웹 UI / UX 테스트 툴 이지만, 문제도 많다. iframe 안에 있는 건 잘 select 가 안되기도 하고, 화면이 작아 컴포넌트가 화면에 보이지 않으면 또 select 할 수 없다. 하지만 브라우저를 있는 그대로 제어 할 수 있다는 게 가장 큰 매력이다.

        ps. selenide 와 같이 쓰면 코드가 많이 개선된다.

        Maintaining and expanding automated regression tests is one of my primary responsibilities at CrowdTwist. We use Selenium to test the front-end parts of our platform.

        Selenium is a great way to automatically test if a build is sane and can be deployed.
