You can extract the function in the source code and use it for testing.
Installation
npm i extract-function --save-devUsing module in source code
var sourceCode = `
/**
* @extract BasicFunc
* */
function basicFunc() {
// OK
}
function test() {
// OK
}
`;
var ExtractFunction = require("extract-function");
var ef = new ExtractFunction(sourceCode);
ef.hasAnnotationName("extract"); // -> `true`
ef.getAnnotationnValue("extract"); // -> `BasicFunc`
ef.getComments(); // -> `/**\n * @extract BasicFunc\n * */`
ef.getClosestFunction(); // -> `function basicFuc() {\n // OK\n }`Using the Command Line
Usage
extract-function --src files --out directory --beautify boolean
Example
$ extract-function -s ./src/**.js -o ./test/extractFiles --beatufiy false

objInFunction: function () {
// OK
},
};
/**
* @extract AnonymousFunction
* */
(function () {
// OK
})();
function outerFunction() {
/**
* @extract InnerFunction
* */
function innerFunction() {
// OK
}
}
});Output : A list of extracted files.
