1. How I Wrote My Own
BDD Framework

2. Earlier last year...
Revamped our Automated UAT Suite
5 Months to Develop
200 Files
7,000 LOC
Pretty Reports

11. Some Stats
500+ lines of human-editable code
94.8% Ruby
5.2% Ragel
90% Code Coverage
Ruby 1.9.3 and 2.0.0
i18n support out of the box

14. Lexing (aka Tokenizing) Analogy

Create a Project A user with a role of <Role> in the
system <Can or Cannot Create> projects

15. Lexing (aka Tokenizing)
Create a Project
================
* A user with a role of <Role> in the system
<Can or Cannot Create> projects
Examples:
| Role | Can or Cannot Create |
| Admin | Can Create |
| User | Cannot Create |
[
[:GROUP, 'Create a Project'],
[:REQUIREMENT, 'Given a user has a role of ...'],
[:TEXT, 'Examples:'],
[:ROW, nil], [:CELL, 'Role' ], [:CELL, 'Can or Cannot Create'],
[:ROW, nil], [:CELL, 'Admin'], [:CELL, 'Can Create'],
[:ROW, nil], [:CELL, 'User' ], [:CELL, 'Cannot Create']
]

Create a Project
A user with a role of <Role> in the system

26. Parsing
GroupNode.new('Create a Project', [
RequirementNode.new('Given a user has a role of ...', [
ExamplesNode.new([
RowNode.new(['Role', 'Can or Cannot Create']),
RowNode.new(['Admin', 'Can Create']),
