To automate Gmail login with pytest, you can use the pytest framework along with the selenium package to simulate user actions on a web browser. Here are the steps you can follow:

Install the pytest and selenium packages using pip:

pip install pytest selenium

Download the appropriate driver for your browser. You can download the Chrome driver from https://sites.google.com/a/chromium.org/chromedriver/downloads. Make sure to select the version that matches the version of your browser.
Create a new Python file for your test, and import the necessary modules:

import pytest
from selenium import webdriver

Create a fixture that sets up the Selenium WebDriver instance:

@pytest.fixture
def browser():
driver = webdriver.Chrome()
yield driver
driver.quit()

This fixture creates a new Chrome driver instance before the test runs, and quits the driver after the test is finished.

Define a test that logs into Gmail using a valid username and password:

def test_login(browser):
browser.get("https://mail.google.com")
email_input = browser.find_element_by_css_selector("input[type='email']")
email_input.send_keys("your-email-address")
next_button = browser.find_element_by_css_selector("button[jsname='LgbsSe']")
next_button.click()
password_input = browser.find_element_by_css_selector("input[type='password']")
password_input.send_keys("your-password")
signin_button = browser.find_element_by_css_selector("button[jsname='LgbsSe']")
signin_button.click()
assert "Gmail" in browser.title

This test navigates to the Gmail login page, enters the email address and password, and clicks the "Next" and "Sign in" buttons. It then checks if the Gmail inbox is displayed by checking if the page title contains the string "Gmail".

Run the test using pytest:

pytest test_gmail_login.py

This will launch the Chrome browser and run the test. If the test passes, you should see a message indicating that one test has passed. If the test fails, you should see an error message indicating the reason for the failure.
