Automated Testing with Playwright, Behave, and Python 🎭🐍

1. Introduction

This project provides an automated end-to-end (E2E) testing framework using:

• Playwright 🎭 for browser automation
• Behave 📝 for Behavior-Driven Development (BDD)

It enables seamless testing across multiple browsers while using Gherkin syntax for clear, human-readable test scenarios.

2. Features ✅

• ✔️ Cross-browser testing (Chromium, Firefox, WebKit)
• ✔️ BDD-style test execution with Gherkin syntax
• ✔️ Headless & non-headless execution
• ✔️ Page Object Model (POM) implementation
• ✔️ Screenshots & trace reports for debugging
• ✔️ CI/CD integration support

3. Setup & Installation ⚙️

🔹 Prerequisites

Ensure you have the following installed:

• Python 3.8+
• Git

🔹 Create a Virtual Environment

python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

🔹 Install Dependencies

pip install -r requirements.txt
playwright install

5. Running Tests 🚀

▶ Run all tests

behave

▶ Run a specific feature file

behave features/login.feature

▶ Run tests in headless mode

behave --tags=headless

▶ Run tests with output

python3 -m behave --no-capture login.feature

5. Writing a Test with Behave 📝

🔹 Feature File (Gherkin Syntax)

📄 features/login.feature

gherkin
Feature: Login Functionality

  Scenario: User logs in successfully
    Given the user is on the login page
    When they enter valid credentials
    And click the login button
    Then they should be redirected to the dashboard

🔹 Step Definitions

📄 steps/login_steps.py

python
from playwright.sync_api import sync_playwright
from behave import given, when, then

@given("the user is on the login page")
def step_open_login_page(context):
    with sync_playwright() as p:
        context.browser = p.chromium.launch(headless=False)
        context.page = context.browser.new_page()
        context.page.goto("https://example.com/login")

@when("they enter valid credentials")
def step_enter_credentials(context):
    context.page.fill("#username", "testuser")
    context.page.fill("#password", "password123")

@when("click the login button")
def step_click_login(context):
    context.page.click("#login-button")

@then("they should be redirected to the dashboard")
def step_verify_dashboard(context):
    assert context.page.url == "https://example.com/dashboard"
    context.browser.close()
