isCalled not working with Ext.fireEvent

[Kurt]

I am trying to figure out if an event has been received.
I know that the event is catched and runs MyApp.util.Barcode.onBarcodeScanned.

Here is my code:

            t.isCalled(
                "onBarcodeScanned",
                MyApp.util.Barcode,
                "Checking if method 'onBarcodeScanned' has been called"
            );

           // this works 
           MyApp.util.Barcode.onBarcodeScanned('T|123123123');
           // this does not work
           Ext.fireEvent('barcodeScanned', 'T|123123123');

           // to allow for more time after the event fired
            t.waitForMs(500, () => {
                t.describe('init', function(t) {})
            });

If I fire the event from the console, it works.
Any idea what to change?

Hello,

You mentioned the SmartMobile.util.Barcode.onBarcodeScanned('T|123123123'); works, which means Siesta correctly intercepts the onBarcodeScanned method in the MyApp.util.Barcode object.

As regarding Ext.fireEvent('barcodeScanned', 'T|123123123'); - this is something specific to your application, sorry, can't say anything about this.

I believe it is not about my app.

Running Ext.fireEvent('barcodeScanned') works fine.
I am getting a console.log from the onBarcodeScanned, but it is not captured by isCalled.

Any other ideas?

I found the problem:

class
    onBarcodeScanned      => gets created by isCalled
    prototype
        onBarcodeScanned  => original Function, which was set to Ext.on('barcodeScanned', ...)

Looks like the Ext.on saves the original method and isCalled uses the newly created one.

Any ideas, what I can do to figure out if the function got called?

Right, this is the order of capturing the onBarcodeScanned method.

The only proper way would be to load your application code first (w/o launching it), install the override in the class'es prototype, then launch the app (so that the app captures the override).

But may be you can test some other side effect of the onBarcodeScanned method call?

[Kurt]

You were right. I can test if the globalEvent has been set.

Instead of :

// I know that this is the  only listener on barcodescanned
let l0 = Ext.globalEvents.events['barcodescanned'].listeners[0];

t.isCalled("fireFn", l0, "Checking if method 'onBarcodeScanned' has been called");

Ext.fireEvent('barcodeScanned', 'T|123123123');

I can use:

t.expect(Ext.globalEvents.events['barcodescanned'].listeners[0]).toBeDefined();

Thanks
