Agenda

  • Traditional Approach
  • Test-driven Approach
  • Advantages & Potentials
  • Implementation

Traditional Approach

(Agency)

A Closing Test Phase

  • Long acceptance test phase in the end
  • A lot of manual testing
  • Regression after bug fixes
  • No guarantee of stable implementation
  • Risky defects liability period

Test-driven Approach

(Agency)

Upfront Specification

  • Acceptance test specification in concept phase
  • Tests implemented by programmers
  • Tests executed automatically
  • Extremely short handover in the end
  • Regression under control

Advantages & Potentials

Why it makes sense

Make The Same Things Earlier

  • No additional budget required
  • Product stability
  • Waste less money for bug fixing
  • Cheap repeatability of testing
  • Focus on advanced quality topics

Implementation

It's all about acceptance criteria

What Do We Need?

  1. User stories
  2. Test specifications

Learning Resources

Testing. Take Back Control
