test-strategy-and-coverage

Define right-sized test layers and coverage priorities for a change.

Test Strategy And Coverage

Trigger Signals

  • the task adds or changes behavior and the right test depth is unclear

Inspect First

  • changed files, existing test layers, and validation commands

Workflow

  1. map the behavioral risk of the change
  2. choose the minimum test layers that cover that risk
  3. identify critical missing cases
  4. summarize the coverage strategy

Output Contract

  • recommended test layers
  • critical cases to cover
  • explicit gaps or acceptable deferrals

Failure Modes

  • no executable validation surface exists

Escalation

  • escalate when a risky change has no trustworthy test path
