Q$5$: Test functions: test$\_$read$\_$data and test$\_$calculate$\_$counts $(5$ pts$)$

Now it's your turn to write your own test functions. Add two test functions test$\_$read$\_$data$()$ and test$\_$calculate$\_$counts to test$\_$data$\_$analysis.py Each function should include: $1)$ at least three assert statements that $2)$ test the functionality of the corresponding method.

Notes:

test$\_$data$\_$analysis.py is missing import statements at the top; be sure to add these

nothing has to be done in the notebook here; however, feel free to test out your work below

def test$\_$ProgrammingLanguage$()$:

out $=$ ProgrammingLanguage$()$

assert type$($out$)==$ ProgrammingLanguage

assert type$($out$.$df$)==$ pd$.$core.frame.DataFrame
