VBot
JSON based visual regression testing library
A visual regression testing library/tool, aims to quickly automate browser-based tests with minimum development overhead. To test flexibly in different testing scenarios, either testing against web UI wired with backends or just static web pages, VBot exposes API to be used with testing frameworks like mocha or ava, etc. Therefore, the test data variables can be updated according to different conditions, in order to decouple from real backends and avoid false negative results. -

BDD / TDD assertion framework for node.js
Chai is a BDD / TDD assertion library for node and the browser that can be delightfully paired with any javascript testing framework. Chai has several interfaces that allow the developer to choose the most comfortable. The chain-capable BDD styles provide an expressive language & readable style, while the TDD assert style provides a more classical feel. Plugins extend Chai's assertions to new contexts such as vendor integration & object construction. Developers can build their own plugins to share with community or use the plugin pattern to DRY up existing tests. You can also use it within the browser; install via npm and use the chai.js file found within the download. Browse our growing directory of custom plugins & vendor integrations to find the best tool for your needs. Chai has an extensive utility belt for plugin developers. Learn how to build your plugins & share. -

Just-API
Test REST, GraphQL APIs
Just-API is a declarative, specification-based test framework for REST, GraphQL APIs. Users can test APIs without writing code, but they can also tap into code when they want to. It reads API test specifications from YAML files and runs them in serial/parallel mode. Test reports can be generated in several formats including HTML and JSON. In simple terms, users build a test suite by providing a set of request and response validation specification in a YAML file. Each suite can have one or more specs. Just-API builds the request, sends it to the server and validates the response as per the specification. Runs test suites in parallel/serial mode. Supports all widely used HTTP methods. Supports x-www-form-urlencoded requests, Multipart requests, File uploads. Built-in Response Validation Constructs(Headers, Cookies, Status code, JSON body, JSON schema) Custom Response validator functions. Supports running custom inline or module javascript sync/async functions. -

Loki
Visual Regression Testing for Storybook
There are a few visual regression tools for the web, but most either cannot be run headless or use phantomjs which is deprecated and a browser nobody is actually using. They usually also require you to maintain fixtures. With react-native it's now possible to target multiple platforms with a single code base, but there's no single tool to test all to my knowledge. Loki aims to have easy setup, no to low maintenance cost, reproducible tests independent of which OS they are run on, runnable on CI, and support all platforms storybook does. -
