I need to make a loop of 3 times and 2 seconds in between each iteration. I tried these 3 options:

Option 1

var casper = require('casper').create({

    verbose: false,

    logLevel: 'debug'

});



casper.start(http://google.com);



casper.on('remote.message', function(msg) {

    this.echo('remote message caught: ' + msg);

})



casper.thenEvaluate(function() {

    var x = 0;

    var intervalID = setInterval(function () {



       console.log(Using setInternal  + x);



       if (++x === 3) {

           window.clearInterval(intervalID);

       }

    }, 2000);



});



casper.run();

Observation: Nothing appeared because the script ended right away before the first setInterval being called.

Option 2

Replaced thenEvaluate() with then() below

for (i=0; i<3; i++) {

    this.wait(2000);

    this.echo('Using this.wait ' + i);

}

Observation: It outputs 3 times right away and then a long wait since this.wait() is async. This is not what I want because I want a delay in between.

Option 3
Replace the part in then() with this below. I was thinking about doing a recursive call to waitFunc() after each wait() being called.

var count = 0;

var waitFunc = function() {

    this.wait(2000, function() {

        if (count < 3) {

            casper.echo('Using this.wait ' + count);

            count++;

            waitFunc();

        }

    });



};

Observation: Nothing printed out on the screen.

So my question is: How to make this.wait or setInterval works in a loop of 3 times like this case?
