Karate DSL vs pytest: What are the differences?
What is Karate DSL? Open Source Web-Services Test Automation Framework. Combines API test-automation, mocks and performance-testing into a single, unified framework. The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. Besides powerful JSON & XML assertions, you can run tests in parallel for speed - which is critical for HTTP API testing.
What is pytest? A full-featured Python testing tool to help you write better programs. A framework makes it easy to write small tests, yet scales to support complex functional testing for applications and libraries. It is a mature full-featured Python testing tool.
Karate DSL and pytest can be primarily classified as "Testing Frameworks" tools.
Karate DSL and pytest are both open source tools. It seems that pytest with 4.42K GitHub stars and 1.06K forks on GitHub has more adoption than Karate DSL with 2.12K GitHub stars and 526 GitHub forks.
