[Feature Request] Ignoring parts of file like functions currently not possible #775

Open sagiavinash opened 7 years ago

sagiavinash commented 7 years ago

I have gone through this doc for coverage ignore comments https://github.com/gotwarlost/istanbul#ignoring-code-for-coverage

but i am not able to ignore a function all together in a file

// module.js
function testedFn() {
  // do something
}

/* istanbul ignore next */
function untestedFn() {
  // do something
}

This is important for transisition phase of codebase from being completely untested to completely tested. Within a module the priority to test a particular function is not the same. So please allow removing certain parts of a file to be ignored.

ESLint has really good ignore comment utilities like /* eslint-disable */ and /* eslint-enable */ that allow progressively making the codebase compliant
