🚀 Step-by-Step Learning Approach
⚡ 1️⃣ Best Practices & Test Optimization (6-7 Days)
Writing scalable and efficient test automation scripts is critical for enterprise-grade automation.
🔹 Optimizing WebDriver Usage
DON’T: Creating multiple WebDriver instances
driver1 = webdriver.Chrome()
driver2 = webdriver.Chrome()
✅ DO: Use a Singleton WebDriver instance
class WebDriverManager:
_driver = None
@staticmethod
def get_driver():
if WebDriverManager._driver is None:
WebDriverManager._driver = webdriver.Chrome()
return WebDriverManager._driver
🔹 Implementing Page Object Model (POM)
Instead of writing test logic inside test cases, separate it into page classes.
✅ Example of POM Implementation:
class LoginPage:
def __init__(self, driver):
self.driver = driver
self.username_field = driver.find_element(By.ID, "username")
self.password_field = driver.find_element(By.ID, "password")
self.login_button = driver.find_element(By.ID, "login")
def login(self, username, password):
self.username_field.send_keys(username)
self.password_field.send_keys(password)
self.login_button.click()
