# Installation

Run `bundle install` to install the gems mentioned in the Gemfile.

To avoid conflict with gems on the machine globally it may be better to specify gem location with:

`bundle install --path ~/.gem`

# Running tests
On the command line type:
`bundle exec rake spec` or simply `bundle exec rake`

# Structure

## Tests
Tests are within the 'spec' folder and end in '_spec'. Setup and teardown for tests is in 'spec/spec_helper'

## Templates
These are the base requests with ERB inside them to create smartly changing requests accoring to the test.yml

## Data
Data used in the test is stored in `config/data` folder. The `data_magic` gem is used by default to read files here.

## Libaries
Libaries to be installed are in 'Gemfile'. Specific gem versions can be specified here and enforeced with `bundle exec rake`

## Reports
Reports are shown in the 'logs' folder. By default Rake produces a junit, an html report, and a `traffic.log` file with the API request and responses in it
