Test yoki skript yakunlangandan so'ng fixture chaqirilishini qanday ta'minlash mumkin?

Testdan so'ng tozalash funksiyasining chaqirilishini ta'minlash uchun odatda teardown yoki finalizator mexanizmlari qo'llaniladi, bu test natijasidan qat'i nazar tozalash kodining bajarilishini kafolatlaydi.

Mashhur test frameworklarida bu maxsus metodlar yoki dekoratorlar orqali amalga oshiriladi:

• pytest da yield parametri bilan fixture ishlatish mumkin:

import pytest

@pytest.fixture
def resource():
    # tayyorlash
    res = acquire_resource()
    yield res
    # tozalash
    release_resource(res)

• unittest (Python) da tearDown() metodi har bir testdan so'ng chaqiriladi:

import unittest

class MyTest(unittest.TestCase):
    def setUp(self):
        self.res = acquire_resource()

    def tearDown(self):
        release_resource(self.res)

    def test_something(self):
        self.assertTrue(use_resource(self.res))

• Java da JUnit bilan, @After yoki @AfterEach anotatsiyalari ishlatiladi:

@After
public void tearDown() {
    releaseResource();
}

Shu tarzda, tozalash yoki resursni bo'shatish bloki, testdan so'ng, hatto test xato bilan tugagan bo'lsa ham, kafolatlangan holda bajariladi.
