Testing a derived function

The test_derived_function should be used when testing a derived function. This helper function is stored within the tests/testthat/helper-utils.R file. The recommended workflow with this function is to:

1. Create a CSV file that has all your test cases for the derived function within the tests/testdata folder
2. Create a testthat test case that reads in that CSV file using the read.csv function
3. Call the test_derived_function function within the test case with the read in CSV file and the function to test

Take a look at the pack_years_fun test within the tests/testthat/test-smoking.R file for an example.
