how to catch browser exceptions for generic handler

[sahas-]

The problem

This is more of a guidance than an issue. I do have stack overflow question open for a while now and thought I'll ask here..sorry ..

I'm looking for guidance to handle browser exceptions in a central place instead of that being thrown out from the PageObjects classes. I'd like to be able to return a custom object with custom error message and stack trace from PageObject class back to the test and let the test handle, use the information for reporting etc..is it possible?

For example, I've my test like this

browser.setValue(_elements.searchbox, envSettings.searchTerm).catch((e)=>{
    let msg = {
           isSuccess: false,
           description: "failed while setting value in google search box",
           stacktrace: e
    }
   return Q.reject(msg);
})

when I run the test, I get this error

browser.setValue(...).catch is not a function

Whats the best way to bubble up all browser errors to a common handler?

Environment

• WebdriverIO version: latest
• Node.js version: system
• Standalone mode or wdio testrunner: wdio
• if wdio testrunner, running synchronous or asnychronous tests: synchronous
• Additional wdio packages used (if applicable):

browser.setValue(...).catch is not a function no wonder, since your are running commands synchronously. You could loop over all commands the browser variable provides and overwrite them using try/catch.

use the information for reporting

What kind if reporting?
