Unexpected error thrown while setting the dropdown

[Nick]

Hi,

Please help me out on this, I'm running a data driven test which encounters this error on a drop down step. I'm pretty sure that I have recorded the steps correctly. But for some reason this error keeps on popping on several iterations.

Failure Information:

 I've tried the selection through Text, Values and Index already but there are iterations which are still being failed.

Birth Region field will only be available once Country of birth is selected, the same can be said on the birth district field. (see attached vid)

I have placed a script step prior to the selection step to help find the element though it has helped significantly as it has not failed most of the data driven test there are still iterations which are failing.

Hello Niccolo,

From the video nothing is clear what exactly is failing. It is a good practice to set the AjaxTimeout to select dropdown steps, since usually they require some time until the content is refreshed. Please check the attached file for more clarity.

If this does not help it will be helpful to provide the test so we can give it a try on our end and investigate further.

Hi Ivaylo

the error is encountered on several iterations during a data driven test. the video posted is just a reference as to where the error happens.

on an average about 5-7 iterations are failing out of 50. will run the test again with your suggestion and provide some feed back if it works
