The `coverageRules` configuration property allows you to define additional rules for what elements should be tracked and which commands constitute coverage for those elements. + +These rules augment (rather than replace) the default interactive element detection, which is based on HTML semantics and WHATWG standards. This allows you to extend UI Coverage to track custom components or count specific commands as coverage without modifying your application code. + +## Syntax + +```json +{ + "uiCoverage": { + "coverageRules": [ + { + "selector": string, + "commands": string[] + } + ] + } +} +``` + +### coverageRules + +_Optional._ Object[] + +An array of objects used to define custom coverage rules for UI Coverage. _**Each object can have the following properties:**_ + +### selector + +_Required._ String (CSS Selector) + +A CSS selector that identifies elements that should be tracked for coverage.
