Question

Need to send a command to the console '$gui.dispatch('callBarcodeHandler', '98783083')' from test. For example, in the test I log in and I need to send a command to scan the barcode.

Using page.evaluate function you can execute an arbitrary code inside the Browser context a.k.a console

Example:

const windowHeight = await page.evaluate('window.innerHeight');
