How to specify parameters and test another function from a different file

Question

I have a test where certain functions are tested in a file. In that file it calls out another function from another file. What can I add to the test so that the test coverage works?

def parse_location
location = extracted_data.get_field(field.location)
if self.field_present("location2"):
location2 = extracted_data.get_field(field.location2)
if self.get_words_out("location2"): #this is located in another file and circleci coverage fails
location2 = parse_word(location2, self.get_words_out("location2")
correct_location = location + " " + location2

How can I add get_words_out("location2") to the test? My pytest looks like:

("location, location2, expected"
[
  (Portugal, Porto, Portugal Porto),
]
)

What I would like to have:

("location, location2, parse_location2, expected"
[
  (Portugal, Porto not needed, not needed, Portugal Porto),
]
)

Having a file where the specific words are listed and called to be parse out works. But I need to have those words called from within the test for the test coverage in circleci not to fail.

Sorry for the messy format.
