Pada percobaan kali ini kita akan melakukan sebuah testing pada sebuah program yang kita buat.
devasc@labvm:~$ python3 -m unittest -h
usage: python3 -m unittest [-h] [-v] [-q] [--locals] [-f] [-c] [-b]
[-k TESTNAMEPATTERNS]
[tests [tests ...]]
positional arguments:
tests a list of any number of test modules, classes and test
methods.
optional arguments:
-h, --help show this help message and exit
-v, --verbose Verbose output
-q, --quiet Quiet output
--locals Show local variables in tracebacks
-f, --failfast Stop on first fail or error
-c, --catch Catch Ctrl-C and display results so far
-b, --buffer Buffer stdout and stderr during tests
-k TESTNAMEPATTERNS Only run tests which match the given substring
Examples:
python3 -m unittest test_module - run tests from test_module
python3 -m unittest module.TestClass - run tests from module.TestClass
python3 -m unittest module.Class.test_method - run specified test method
python3 -m unittest path/to/test_file.py - run tests from test_file.py
usage: python3 -m unittest discover [-h] [-v] [-q] [--locals] [-f] [-c] [-b]
<output omitted>
For test discovery all test modules must be importable from the top level
directory of the project.

Kemudian buat sebuah fungsi dengan nama test_json_search.py
from test_data import *
def json_search(key,input_object):
ret_val=[]
if isinstance(input_object, dict): # Iterate dictionary
for k, v in input_object.items(): # searching key in the dict
if k == key:
temp={k:v}
ret_val.append(temp)
if isinstance(v, dict): # the value is another dict so repeat
json_search(key,v)
elif isinstance(v, list): # it's a list
for item in v:
if not isinstance(item, (str,int)): # if dict or list repeat
json_search(key,item)
else: # Iterate a list because some APIs return JSON object in a list
for val in input_object:
if not isinstance(val, (str,int)):
json_search(key,val)
return ret_val
print(json_search("issueSummary",data))Fungsi tersebut dihubungkan dengan file test_data.py yang tadi telah dibuat. fungsinya untuk melakukan unit testing pada file tersebut, jika tidak terdapat error maka fungsi tersebut tidak mengalami kesalahan/error.
