Pytest - no tests ran | 易学教程

问题

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?

回答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_ in its filename.

回答2:

As simple as it looks:

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

Find more about the pytest conventions here.

try add @classmethod on the top of setUP and tearDown.

Did you execute the class itself?
I don't see in this code you are showing that you call the class or definitions to run.
For example, in python you run a class or definition like this:

class Hello():
    # __init__ is a definition runs itself. 
    def __init__(self): 
        print('Hello there')
        # Call another definition. 
        self.andBye()

    # This definition should be calles in order to be executed. 
    def andBye(self):
        print('Goodbye')

# Run class 
Hello()
