Continue asking about monkey patches I use :)
While building object-oriented page objects (sic), I've came to the idea of
adding `Watir::Element#try` which will try to run code against element, but if
it's not present (`UnknownObjectException` is raised), it will return `nil`.
Just like `#try` in ActiveSupport, but not catching `NoMethodError`.
I needed this because I had the same page accessible to two user roles.
Depending on the role, some elements could be present and some not. For example:
```ruby
def user
{
:name => user_div.div(:class => 'name').text, # shown to all roles
:status => user_div.div(:class => 'status').text, # shown to admin only
}
end
```
Apparently, this code will raise `UnknownObjectException` when try to retrieve
`:status` if currently logged in user role is not admin.
So I made it like:
```ruby
def user
{
:name => user_div.div(:class => 'name').text, # shown to all
roles
:status => user_div.div(:class => 'status').try(:text), # shown to admin
only
}
end
```
Now, `:status` will fail the test only on verification step (if needed).
I understand that this may be a problem for other projects with different
codebase, so if you think it's a bad idea, I'll just close the issue.
