What is Automated Software Testing?

Automated software testing utilizes scripts or tools to verify that your software functions as expected. Instead of manually clicking through every feature, you write tests that run automatically, saving time, reducing human error, and catching bugs early.

Analogy:
Think of automated testing as having a robot assistant that checks your code every time you make a change.

Why Use Python for QA?

Python is one of the most popular languages for automated testing because: - It’s easy to read and write, even for beginners. - It has powerful testing libraries like unittest, pytest, and Selenium. - It integrates well with CI/CD tools for continuous testing. - It’s widely used in both web and software QA.

Types of Automated Tests

• Unit Tests: Check individual functions or components.
• Integration Tests: Ensure different parts of the app work together.
• End-to-End (E2E) Tests: Simulate real user scenarios from start to finish.
• Regression Tests: Make sure new changes don’t break existing features.

Getting Started: Prerequisites

• Python basics: Variables, functions, loops

• Key libraries:
  • unittest and pytest for core testing
  • selenium for web automation
• Installation:
  bash pip install pytest selenium
• A code editor: VS Code, PyCharm, or Jupyter Notebook

Step 1: Setting Up Your Python Testing Environment

Install the required libraries and create a new Python file for your tests:

pip install pytest selenium

Import the basics:

import pytest

Step 2: Writing Your First Automated Test

Let’s write a simple unit test for a function that adds two numbers.

def add(a, b):
    return a + b

def test_add():
    assert add(2, 3) == 5
    assert add(-1, 1) == 0
    assert add(0, 0) == 0

Run your test in the terminal:

pytest test_example.py

Result:
You’ll see output showing which tests passed or failed, making it easy to spot issues.

Sample Test Data Table

Input A	Input B	Expected Result
2	3	5
-1	1	0
0	0	0

Note:
This table illustrates how you can structure test cases for clarity and coverage.

Step 3: Expanding to Web Application Testing

For web apps, use Selenium to automate browser actions. Here’s a basic example:

from selenium import webdriver

driver = webdriver.Chrome()
driver.get('https://example.com')

title = driver.title
assert "Example Domain" in title

driver.quit()

What this does:
- Opens Chrome - Navigates to a website - Checks if the page title is correct - Closes the browser

Best Practices for Automated Testing

• Write clear, independent tests: Each test should check one thing.
• Use descriptive names: Make it obvious what each test does.
• Automate regularly: Integrate tests into your development workflow.
• Keep tests up-to-date: Update or remove tests as your app changes.
• Document your tests: Help others understand and maintain your suite.
