UI automation code on a frame, works fine in Chrome/MSEdge but fails in Firefox and Safari

问题

I'm using Karate v0.9.6.RC1. The code is something like this: * switchFrame(1) And input('input[name='cardnumber']','xxxxxxx')

This works fine in Chrome or Edge browser but fails in Firefox or Safari. I tried using different methods like Click, Input, Retry etc after switching to frame but Firefox/Safari doesn't even recognise the object. Also tried different locators. It fails with the below error:

21:14:08.687 request:

I'm not sure if I'm missing something here. Any inputs would be appreciated.

Yes I don't think the FF and Safari browsers implement frame-switching correctly. I could be wrong, but having tried a bit and given up - you are welcome to dig into the code / spec and fix this. PR-s welcome !

I also suggest exploring if you can achieve this via JS, here are some ideas: https://stackoverflow.com/a/60800181/143475

Note that Karate is very easy to contribute to, we have a detailed guide: https://github.com/intuit/karate/wiki/Developer-Guide
