Task $1$: Develop Unit Tests for Load Data Module

As a team, you will write four different test cases for your load$\_$data module. Remember to use

automated testing, as you learned during the lectures. You need to import the check module

explained during the lectures. Use the functions in the check module in your implementation.

You are not allowed to modify the check module.

Docstring and type annotations are not required for this lab.

For your tests, use the characters$-$test.csv file provided.

STEP $1$

$1.$ Read the descriptions of the tests below.

$2.$ Decide who is writing which test.

Test $1$: Functions Return a List

In a file named test$1.$py$,$ write a test function named test$\_$return$\_$list to test that all six functions in

the load data module return a list.

For each function except load$\_$data you need to provide at least $3$ test cases:

$5$ functions $*3$ test$/$function $=15$ test cases

For function load$\_$data, you need to provide $6$ test cases.

That$$s $21$ test cases in total.

The function is the folowing:

def character$\_$occupation$\_$list$($file: str$,$ occupation: str$)$:

occupation$\_$ls $=[]$

targetfile $=$ open$($file$,"$r$")$

first$\_$line $=$ True

for line in targetfile:

person $=\{\}$

line $=$ line.strip$(\text{'}$

$\text{'}).$split$(\text{'},\text{'})$

if first$\_$line:

first$\_$line $=$ False

header $=$ line

else:

if occupation in line:

for i in range$(1,$ len$($header$))$:

if i $==6$:

person$[$header$[$i$]]=$ float$($line$[$i$])$

elif i $==8$:

person$[$header$[$i$]]=$ str$($line$[$i$])$

else:

person$[$header$[$i$]]=$ int$($line$[$i$])$

occupation$\_$ls$.$append$($person$)$

targetfile.close$()$

return occupation$\_$ls
