Sample Code §

Testing Flask App §

import unittest
from datetime import datetime
from freezegun import freeze_time
from module_03_ci_culture_beginning.homework.hw1.hello_word_with_day import (
    GREETINGS,
    app,
)

class TestHelloWorldWithDayApp(unittest.TestCase):
    def setUp(self):
        app.config["TESTING"] = True
        app.config["DEBUG"] = False
        self.app = app.test_client()
        self.base_url = "/hello-world/"
    def test_username_in_response(self):
        username = "Username"
        response = self.app.get(self.base_url + username)
        response_text = response.data.decode()
        self.assertIn(username, response_text)
    def test_weekday_in_response(self):
        username = "Username"
        # Create dates from monday (index = 0) to sunday (index = 6)
        datetimes = (datetime(2023, 10, day) for day in range(9, 16))
        # Test response for each weekday
        for weekday in range(0, 7):
            with freeze_time(datetimes):
                response = self.app.get(self.base_url + username)
                response_text = response.data.decode()
                self.assertIn(username, response_text)
                self.assertIn(GREETINGS[weekday], response_text)

Using self.subTest() §

import unittest
from module_03_ci_culture_beginning.homework.hw2.decrypt import decrypt

class TestDecryptFunction(unittest.TestCase):
    test_cases = (
        ("абра-кадабра.", "абра-кадабра"),
        ("абраа..-кадабра", "абра-кадабра"),
        ("абраа..-.кадабра", "абра-кадабра"),
        ("абра--..кадабра", "абра-кадабра"),
        ("абрау...-кадабра", "абра-кадабра"),
        ("абра........", ""),
        ("абр......a.", "a"),
        ("1..2.3", "23"),
        (".", ""),
        ("1.......................", ""),
    )
    def test_decrypt(self):
        for test_case in self.test_cases:
            encrypted, decrypted = test_case
            with self.subTest(encrypted=encrypted, decrypted=decrypted):
                self.assertEqual(decrypt(encrypted), decrypted)
