Following Design Guidelines & Achieving More By Writing Less Code

The Core Idea

Well-designed frameworks favor reusable, generic components over one-off, tightly-coupled scripts — the goal is to write a small amount of well-structured code that can support a large number of test scenarios.

Practical Guidelines

• Prefer configuration and data over duplicated code (data-driven design).
• Extract repeated logic into shared utility or base classes.
• Keep methods small, single-purpose, and clearly named.
• Avoid hardcoding values that are likely to change.

The Payoff

Following these guidelines means adding a new test scenario is often as simple as adding a new row of data, rather than writing and maintaining an entirely new script.
