### Beginner Task ###
# This test will not pass. Fix the function or the test so that it passes.
# Discuss the way you made it pass with other group members.

#' Check if animal is likely a dog
#'
#' @param height_cm Integer. Dog's height from floor to shoulder, rounded to the nearest centimeter.
#' @param has_fur Boolean. Indicates whether the animal has fur.
#'
#' @return List. Animal's parameters and a boolean indicating whether animal might be a dog.

            expect_equal(dog_status$`Dog Parameters`, "Fur:TRUE, Height (cm):40")
          })

### Advanced Task ###
# Begin with the function you created in Parts 1-5. 
# Write a test for your function. See above for an example of a test.
# Some test possibilities: expect_equal, expect_error, expect_length, expect_lt, expect_gt
# If you have time, explain your code to other group members.
