> Apply foundations 2 in Testing Fundamentals.

## Understand Inputs, data, and configuration

In **Testing Fundamentals**, use foundations 2 to connect the problem, constraints, and measurable outcome before selecting an approach.

## Practise the workflow

Start small, verify one result, and record what the evidence changes.

## A useful comparison

Think of this as a route plan: each step should lead to a checked destination.

Check your reasoning.
