Add a test_write_results_without_filepath

[kimberlythegeek]

Should add a test to verify that write_results still works when no file name or path is given

@terrameijar This occurred to me when reviewing your pr; feel free to pick this up if desired

@kimberlythegeek Thanks! On it.

I noticed that the test_write_results_to_file() test writes results data to a JSON file that doesn't get deleted at the end of the test. I think this file should be deleted after the test run is over. We can use the tempfile module to take care of removing the file after it has been read and the test is over. What do you think @kimberlythegeek ?

@terrameijar Great idea! I hadn't thought of that :)

@kimberlythegeek Is this issue still open?, I would like to work on it if thats the case.

apologies, @hzk120 , looks like this was fixed in #163
