babel-plugin-babel-strip-test-code

Testing your private functions made safe and easy

What does it do?

strips exports __test__ = ... code from your codebase allowing you to expose private functions for testing

How do I do it?

Add an ES2015 export to your js file and call it __test__ which will allow you to expose your private functions in test mode but when you run babel on your code for production, it will strip the exports from the production code.

Example

In

let foo;
 
function funkyFunc(str) {
    console.log(str);
}
 
function testFunc() {
    funkyFunc('over here');
}
 
export const __test__ = {
    test1: funkyFunc,
    test2: testFunc
};
 
export default funkyFunc;
 

Out

let foo;
 
function funkyFunc(str) {
    console.log(str);
}
 
function testFunc() {
    funkyFunc('over here');
}
 
export default funkyFunc;
