In this case, you have two options

1) Add a unique class on each field you want to select during selenium test

<field name="partner_id" class="selenium_partner"/>

2) Patch the rendering engine and add new html `name` attribute on each field same as the field name

Note: The second option will break when form view has one2many field with an editable tree view and both contain same field name

In first option, They already have classes, so cannot create another class for the same field.

<field name="company_id" class="c_field-65" required="1" options='{"no_open": True,"no_create":True }'/>

Can you please explain the second option in more detail please?

for the first option, if you add class from xml it will append the class so even though there is already existing class

anyway for the second option,

Form view rendered set unique label through `setIDForLabel` of abstract field

so in abstract file /addons/web/static/src/js/fields/abstract_field.js

add below line in `setIDForLabel` function

this.getFocusableElement().attr('name', this.name);

Thanks Ravi Gadhia , Adding a new class helps (Y). Thanks alot for your Answer !!!!
