TMF vs Google Puppeteer comparison of testing frameworks
What are the differences between TMF and Google Puppeteer?

	TMF https://github.com/bowsersenior/tmf	Google Puppeteer https://developers.google.com/web/tools/puppeteer
Programming language	Ruby	JavaScript
Category	Unit Testing	Browser Automation
General info	TMF is a minimal testing tool for ruby TMF is a very small testing tool, it's not even a gem, you just copy the code and you're done. it uses just two methods to test: assert and stub	Puppeteer is a Node library which provides browser automation for chrome and chromium Puppeteer runs headless by default, but can be configured to run full (non-headless) Chrome or Chromium; It provides a high-level API to control Chromium or Chrome over the DevTools Protocol
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	No
Client-side Allows testing code execution on the client, such as a web browser		Yes Most things you can do manually in the browser can be done using puppeteer, therefore you can create a testing environment for your tests to run directly. You can test front-end functionality such as UI testing with puppeteer
Server-side Allows testing the bahovior of a server-side code	Yes You can test back-end components with TMF	No
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	No	N/A
Group fixtures Allows defining a fixed, specific states of data for a group of tests (group-fixtures). This ensures specific environment for a given group of tests.	No	N/A
Generators Supports data generators for tests. Data generators generate input data for test. The test is then run for each input data produced in this way.	No	No
Licence Licence type governing the use and redistribution of the software		Apache License 2.0
Mocks Mocks are objects that simulate the behavior of real objects. Using mocks allows testing some part of the code in isolation (with other parts mocked when needed)	No	No
Grouping Allows organizing tests in groups	No	No
