setTimeout not working with node.js

rated 0 times [ 86] [ 6] / answers: 1 / hits: 16899 / 9 Years ago, thu, april 23, 2015, 12:00:00

I am writing mocha test cases to test the following steps. I intend to make an API call and wait for 30 minutes before calling another API. I am using an internal node API which was written to call REST APIs to write this test case. But for some reason, setTimeout is not waiting for the given ms.
Can someone please help me?

 describe('Checkout - ', function() {

   before(function() {

     lapetus = test.Lapetus;

   });

  it('Get purchase contract after session is expired [C123]',     function(done) {

    this.timeout(180000000);

    lapetus.run(function() {

     // create customer

     ......



     // create new cart and add one item

     ......



    // create new contract with empty cart id

    .......

    var pc_id =....;



    // wait for 30 minutes for the session to expire

    console.log('wait... ' + new Date);

    this.setTimeout(getPC(lapetus,pc_id), 18000000);

    console.log('ok... ' + new Date);

    done();

  });

});



  var getPC = function(lapetus, pc_id){

   // get newly created purchase contract and verify session expired message throws

    .....

    ......

 };

  });

It does not wait 30 minutes. The call back I put in (the getPC method) executes immediately.

Any help is appreciated.

Thanks

Your call back is executing immediately because you're calling it then and there.

Change it to this.setTimeout(function() { getPC(lapetus,pc_id); }, 18000000); so that what you want to execute is in a function for setTimeout to call.

** Edit **

In relation to my last comment. You should move your ok... inside of the function you've put inside of setTimeout. This will cause the ok... to execute right before getPC is called.

this.setTimeout(function() {

    console.log('ok... ' + new Date);

    getPC(lapetus,pc_id)

}, 18000000);

It is important to understand that setTimeout will only start a timer which will execute your code later. setTimeout is going to start that timer, and not wait for it to finish. It will move to the next bit of code once it is done starting that timer.
