Creating Test Scripts in Selenium

 Selenium is one of the most popular open-source tools for automating web application testing. It supports multiple programming languages like Java, Python, C#, and works with major browsers including Chrome, Firefox, and Edge. Creating test scripts in Selenium enables QA engineers to simulate real user interactions, validate application behavior, and ensure software quality efficiently.

What is a Selenium Test Script?

A Selenium test script is a piece of code written to perform specific actions on a web page — such as clicking a button, entering text, verifying elements, or navigating between pages — just as a real user would do. These scripts can be used for functional, regression, and smoke testing.

Getting Started: Tools and Setup

Install Java or Python (depending on your language of choice).

Download Selenium WebDriver for your browser.

Set up your IDE (Eclipse for Java, PyCharm/VS Code for Python).

Add Selenium libraries to your project.

For Java (Maven):

<dependency>

  <groupId>org.seleniumhq.selenium</groupId>

  <artifactId>selenium-java</artifactId>

  <version>4.18.0</version>

</dependency>

For Python:

pip install selenium

Example: Basic Selenium Test Script (Python)

from selenium import webdriver

from selenium.webdriver.common.by import By

driver = webdriver.Chrome()

driver.get("https://example.com")

# Locate input field and enter text

driver.find_element(By.NAME, "username").send_keys("testuser")

# Click login button

driver.find_element(By.ID, "loginBtn").click()

# Verify page title

assert "Dashboard" in driver.title

driver.quit()

This script opens a website, enters login credentials, clicks a button, and checks if the login was successful.

Best Practices for Writing Selenium Scripts

Use Page Object Model (POM) to organize test code and improve maintainability.

Implement explicit waits to handle dynamic content:

from selenium.webdriver.support.ui import WebDriverWait

WebDriverWait(driver, 10).until(lambda d: d.title == "Dashboard")

Use assertions to validate test outcomes.

Maintain a test data strategy using data files or parameters.

Conclusion

Creating test scripts in Selenium empowers testers to automate repetitive tasks, reduce human error, and accelerate release cycles. With its wide language support and robust capabilities, Selenium remains a go-to choice for web application automation. Mastering script creation is the first step toward building a reliable and scalable test automation framework.

DevOps vs Agile: Key Differences Explained

 In the modern software development landscape, DevOps and Agile are two dominant methodologies that aim to deliver high-quality software efficiently and reliably. While they share common goals—such as faster releases, improved collaboration, and continuous improvement—they are not the same. This blog explains the key differences between DevOps and Agile, their core principles, and how they complement each other. Definition and Focus Agile is a software development methodology focused on iterative development, where requirements and solutions evolve through collaboration between cross-functional teams. Agile emphasizes adaptability, customer feedback, and working software delivered in small, frequent iterations (sprints). DevOps, on the other hand, is a software delivery approach that bridges the gap between development and operations teams. It emphasizes automation, continuous integration/continuous delivery (CI/CD), monitoring, and collaboration to achieve faster, more reliable so...

Regression Analysis in Python

Regression analysis is one of the most widely used statistical techniques in data science and machine learning. It helps us understand relationships between variables and make predictions. In this blog, we’ll walk through the basics of regression analysis using Python and its popular libraries. 🔍 What is Regression Analysis? Regression analysis is a predictive modeling technique used to examine the relationship between a dependent (target) variable and one or more independent (predictor) variables. The most common type is linear regression, which assumes a linear relationship between variables. For example, predicting house prices based on area, location, and number of bedrooms is a regression problem. 🛠 Libraries Required Before we start, install the required Python libraries: pip install numpy pandas matplotlib seaborn scikit-learn Now, let's import them: import numpy as np import pandas as pd import matplotlib.pyplot as plt import seaborn as sns from sklearn.linear_model impor...
