How do you mock an outer method calling a callback using sinon?
Example given the following code, getText should return 'a string' as response in the callback function

sinon.stub(a, 'getText').returns('a string')

let cb = function(err, response) {

   console.log(response)

}

a.getText('abc', cb)

and it should produce the output 'a string' since it calls callback function cb but there is no output

You can use callsArgWith

sinon.stub(a, 'getText').callsArgWith(1, null, 'a string')

let cb = function(err, response) {

   console.log(response); // 'a string'

}



a.getText('abc', cb)
