Is it possible to write a unit test with Jest for a JavaScript file that is namespaced using the below format?
// utilities.js
var MyApp = MyApp || {};
MyApp.Common = MyApp.Common || {};
MyApp.Common.Utilities = new function(){
this.getSomething = function(){ // Need to unit test this function
return 'Something';
}
}
If not, is there a better way to structure the namespaces to allow for unit testing?
If you export MyApp like following example then in utilities.test.js you can
const {MyApp} = require('./utilities');
it('should work', ()=>{
expect(MyApp.Common.Utilities.getSomething()).toEqual('something');
});
