What to change
Choose regression coverage by dependency as well as by edited filename. Ask the supplier to identify which routes use the changed component and select representative important cases. Include a control path that should retain its behaviour. The owner need not inspect every implementation detail, but should see why the chosen sample is capable of detecting a shared failure. Preserve those examples with the component's change record for future releases.
A worked example
Illustrative example
Illustrative test: A shared navigation change is exercised from a guide, a service page and a directory.
How to check the result
The sample covers the dependency's real public reach.
A mistake to avoid
A file list can understate the impact of one reusable component.
Your action checklist
Use these checks to prepare a discussion with your team or supplier. Tick a check when you have recorded the decision or evidence, rather than when a feature has simply been promised.
