Help please: Learning developer's confusion on texting
imagine there is function which does something like this.function someFunc(arguments, callback) { // some kind of I/O operation. someAsyncFunction([args. . . ], function(err, res) { // do some processing on the data. callback(null, attemptingNick); }); }How do you write tests for this? If I try and write things inside callback in a separate functions then functions get really tiny.
