Browser Automation & Testing

Selenium

Selenium is an open-source automation testing framework primarily used for web application testing. It provides a suite of tools, including Selenium WebDriver for browser automation, Selenium IDE for record-and-playback testing, and Selenium Grid for parallel test execution across multiple environments. It supports various programming languages like Java, Python, C#, and JavaScript, enabling developers to write test scripts that simulate user interactions with web browsers.

Also known as: Selenium WebDriver, Selenium IDE, Selenium Grid, Selenium RC, Selenium 2.0

🧊Why learn Selenium?

Developers should learn Selenium when they need to automate functional, regression, or cross-browser testing for web applications, as it helps ensure software quality and reduces manual testing efforts. It is particularly useful in agile and DevOps environments for continuous integration and delivery pipelines, where automated tests can be integrated with tools like Jenkins or GitHub Actions. Specific use cases include testing dynamic web pages, handling complex UI elements, and validating web applications across different browsers and operating systems.

.env is a file format and tool used to store environment variables, which are key-value pairs that configure application settings like API keys, database URLs, and other sensitive or environment-specific data. It allows developers to separate configuration from code, making applications more secure and portable across different environments (e.g., development, testing, production). Tools like dotenv in Node.js or python-dotenv in Python parse .env files to load these variables into the application's environment at runtime.

.htaccess (Hypertext Access) is a configuration file used on Apache web servers to control directory-level settings, such as URL redirection, access control, and performance optimizations. It allows developers to override global server configurations for specific directories without modifying the main server configuration files. This file is commonly used for tasks like enabling HTTPS, blocking IP addresses, or setting custom error pages.

2D Drafting is the process of creating technical drawings and schematics in two dimensions using specialized software, primarily for engineering, architecture, and manufacturing design. It involves producing precise, scaled representations of objects, components, or structures with detailed annotations, dimensions, and symbols to communicate design intent and specifications. This skill is foundational for translating conceptual ideas into actionable plans for construction, fabrication, or analysis.

2D Drafting Tools

2D drafting tools are software applications used to create precise technical drawings, schematics, and blueprints in two dimensions. They enable engineers, architects, and designers to produce detailed plans with accurate measurements, annotations, and geometric shapes. These tools are essential for documenting designs before moving to 3D modeling or physical construction.

2D Drawing Review

2D Drawing Review refers to the process and software tools used to examine, annotate, and collaborate on two-dimensional technical drawings, such as blueprints, schematics, or CAD designs. It involves checking for accuracy, compliance with standards, and identifying errors or improvements in engineering, architecture, or manufacturing contexts. Tools for this purpose often include features like markup, version control, and real-time collaboration to streamline review cycles.

2D Graphics Software

2D graphics software refers to computer programs used to create, edit, and manipulate two-dimensional digital images, illustrations, and designs. These tools provide features like drawing, painting, vector graphics, image editing, and layout design for applications such as digital art, UI/UX design, game sprites, and print media. They range from professional suites like Adobe Photoshop to free alternatives like GIMP and Inkscape.
