<h1 class="center">Visual Regression Testing for Storybook</h1>

## Rationale

There's 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.

## Supported platforms

* Chrome in docker (recommended)
* Local Chrome application
* iOS simulator
* Android emulator

## Rationale

There's 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 generally also require you to maintain fixtures and/or only support one platform. 

## Aims

* Easy setup
* No additional maintenance cost
* Reproducible tests independent of OS
* Support all platforms storybook does

## Supported platforms

* Chrome in docker (recommended)
* Local Chrome application
* iOS simulator
* Android emulator
