Conftest.py concept

To access fixtures in all the test files then we need to create a method and append the required fixtures to it in conftest.py file.

Here test file name conftest.py is predefined,We shouldn’t change the name of the file.

When a defined fixture is not found in the test file where the test methods are created then it will search in the conftest.py file. If it found the required fixture then it will execute it accordingly.


In below example we have created conftest.py and 2 test files as ( test_PytestExample1.py and test_PytestExample2.py)

pytest conftest

conftest.py

import pytest


@pytest.fixture
def fixtureMethod():
    print("This is a Fixture Method")

test_PytestExample1.py

def test_methodA(fixtureMethod):
    print("This is method A")


def test_methodB(fixtureMethod):
    print("This is method B")

test_PytestExample2.py

def test_methodC(fixtureMethod):
    print("This is method C")


def test_methodD(fixtureMethod):
    print("This is method D")

Run the below command to execute all the test files in the package.

pytest -v -s
