Lesson 1
Why equal coverage is weak strategy
Systems contain different consequences and failure probabilities, so testing effort should not be distributed evenly.

Risk-Based Test Design
Prioritise testing using likelihood, consequence, change complexity, usage and detectability instead of treating every requirement equally.

Lesson 2
Risk dimensions
Consider customer impact, financial exposure, operational disruption, regulatory consequence and technical complexity.
Lesson 3
Change-based risk
Recent code changes, integration touchpoints and architectural coupling can increase regression probability.
Lesson 4
Coverage as evidence
Coverage is meaningful when it maps to risks and behaviours, not when it is merely a count of cases.
Lesson 5
Exit decisions
Communicate residual risk clearly when time prevents exhaustive testing.
Hands-on practice
Do something with what you learned
Do not just tick these mentally. Write the query, create the test matrix, refactor the code, or document the decision. Practical evidence is the point.
