# Prerequisites
This creates files within an existing folder. It could add onto an existing project.
For a new project create a folder and be at it's location on the command line

```
mkdir soaspec_test
cd soaspec_test
```

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

## 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
