Pytest - no tests ran

Question

I'm using pytest and selenium. When I try run my test script:

import pytest
from selenium import webdriver
from pages import *
from locators import *
from selenium.webdriver.common.by import By
import time

class RegisterNewInstructor:
    def setup_class(cls):
        cls.driver = webdriver.Firefox()
        cls.driver.get("http://mytest.com")

    def test_01_clickBecomeTopButtom(self):
        page = HomePage(self.driver)
        page.click_become_top_button()
        self.assertTrue(page.check_instructor_form_page_loaded())


    def teardown_class(cls):
        cls.driver.close()

The message shown is: no tests ran in 0.84 seconds

Could someone help me run this simple test?

Answer 1

According to the pytest test conventions, your class should start with Test to be automatically picked up by the test discovery mechanism. Call it TestRegisterNewInstructor instead.

Or, subclass the unittest.TestCase:

import unittest

class RegisterNewInstructor(unittest.TestCase):
    # ...

Also keep in mind that the .py test script itself must begin with test_ or end with _test in its filename.

Answer 2

As simple as it looks:

1. Make sure that your file name matches the pattern: test_*.py or *_test.py.
2. Make sure that your function name starts with the test prefix.
