Test Strategy Successful Agile • Strategy • Team

Prerequisites • Continuous Integration • Test Automation

Automated Tests Rust Code Breaks Sync Fails Trust Fails

Two Scenarios • Fix 1 to 3 tests • Fix 800 tests

Your Code

Public API Supporting Classes

Focused Tests

Tests Broad

Unit Tests • Exercise one unit • No external resources • Fast • Focused • Labor intensive

Mock Client Test • A system or module • Integration test • Broad • Slow

Tests Require • Continuous Integration • Frequent check-ins

Three Strategies • Test Driven Development • Defect Driven Testing • Blitzkrieg

TDD • Write a test that fails • Write just enough code • Repeat

TDD • Drives design • Creates a solid product • Requires enlightenment

• Find a bug • Add a test • Jazz it up DDT

DDT • Inoculates your code • Incrementally builds suite • Retrofit

BK • March across the product • Breadth, not depth • Create templates

BK • Jump start the effort • Same page • Requires enlightenment

Scenario One • New project • Enlightenment TDD + BK + DDT

DDT • No enlightenment Scenario Two • New project

Scenario Three • Existing project • Enlightenment BK + DDT

Scenario Four • Existing project • No enlightenment DDT

Scenario Five • Existing product • Some enlightened developers DDT

Summary • Test categories: Focused & Broad • Test types: Unit & Mock Client • Strategies: TDD, DDT, BK

Your Goal • Pick a strategy • Start within two days • Use it one month • Re-evaluate
