SlimerJS vs. Zombie.js vs. blanket.js vs. python-sql Comparison Chart

SlimerJS is a free, open source scriptable browser for web developers, allowing interaction with web pages through external JavaScript scripts. It enables tasks such as opening web pages, clicking links, and modifying content, making it useful for functional tests, page automation, network monitoring, screen capture, and web scraping. Unlike PhantomJS, SlimerJS runs on top of Gecko, the browser engine of Mozilla Firefox, instead of WebKit, and can operate in both headless and non-headless modes. APIs of SlimerJS are similar to the APIs of PhantomJS but there are a few differences in their behavior. However, most of the scripts for PhantomJS run perfectly well with SlimerJS right now.

A seamless JavaScript code coverage library. Blanket.js is a code coverage tool for JavaScript that aims to be easy to install, easy to use, and easy to understand. Blanket.js can be run seamlessly or can be customized for your needs. JavaScript code coverage compliments your existing JavaScript tests by adding code coverage statistics (which lines of your source code are covered by your tests). Parsing the code using Esprima and node-falafel, and instrumenting the file by adding code tracking lines. Connecting to hooks in the test runner to output the coverage details after the tests have been completed. A Grunt plugin has been created to allow you to use Blanket like a "traditional" code coverage tool (creating instrumented copies of physical files, as opposed to live-instrumenting). Runs the QUnit-based Blanket report headlessly using PhantomJS. Results are displayed on the console, and the task will cause Grunt to fail if any of your configured coverage thresholds are not met.
