# Roundabout

A Rails Engine that generates a page transition diagram for your Rails app from the system tests and shows it on the browser.

![Example](https://raw.githubusercontent.com/amatsuda/roundabout/master/example_diagram.png)

## Requirements

- Ruby 2.x

- Rails 3 or newer

- RSpec / Minitest / TestUnit

- Capybara

## Installation

Bundle this gem to your Rails app's development and test env:

```ruby
  gem 'roundabout', group: [:development, :test]
```

## Usage

Run the whole tests with `ROUNDABOUT` envvar (I suppose parallel spec is not supported ATM):

```bash
% ROUNDABOUT=1 rails test:system
```

All page transitions via capybara will be recorded, then woven into a diagram.

To see the generated diagram, just browse at `http://localhost:3000/roundabout`.
You can also download a png image version and a PDF version from that page.

## Example

The image shown at the very top of this document was generated from [Redmine](https://github.com/redmine/redmine) project's codebase.

Each box shows Rails controller/action name, and the arrows between them means as follows:

Dark:   Redirect
Red:    Form
Yellow: Link

## Contributing

Send me a PR with a patch.

## TODO

- More tests (with multiple kinds of testing frameworks, capybara drivers, Rails versions, etc.)

- Configure CI

- Parallel tests support

- etcetcetc.
