patch testing
Skin sensitivity check
Patch testing is a method of checking for allergic reactions by applying small amounts of substances to the skin, usually on the back, and leaving them in place for a set period.
Dermatologists use patch testing to identify contact allergies—reactions to metals, fragrances, preservatives, or other materials: Patch testing confirmed she was allergic to nickel.
In software development, patch testing means verifying that a code fix works correctly before deployment.
