Basic commands for interacting with web elements using Selenium

‍Selenium offers an array of commands designed to engage with web elements seamlessly while navigating a web page. Below, we'll delve into some fundamental and widely utilized commands for interacting with web elements:

Finding Elements:

findElement(By.locator): This is the core method for finding elements on a webpage.

Interaction Commands:

.click(): Simulates clicking on an element.

.sendKeys("text"): Enters the specified text into a text field or text area.

.clear(): Clears the text from a text field or text area.

.submit(): Submits a form. This is typically used with form elements.

Verification Commands:

.isDisplayed() : Checks if the element is visible on the webpage.

.isEnabled() : Checks if the element is enabled for interaction.

.isSelected() : Checks if an element like a checkbox or radio button is selected.

Getting Information:

.getText() : Retrieves the text content of an element.

.getAttribute(“attribute _name”) :Gets the value of a specific attribute of the element.

Key Components of a Selenium Test Framework

Selenium is a robust tool that allows you to manage web browsers programmatically. It functions well across different browsers and operating systems and supports scripting in various languages like Python, Java, and C#. For our purposes, we'll be using Python. Selenium comprises four core components : Selenium IDE, Selenium RC, Selenium WebDriver, and Selenium Grid.

Selenium IDE:

Selenium IDE, a Firefox Add-On and Chrome Extension, is an Integrated Development Environment within the Selenium Suite. You can record, edit, and run Selenium tests using Selenese commands, making it ideal for both developers and software testers to automate web application interactions. While initially facing minimal maintenance, Selenium IDE has seen recent improvements and offers flexibility in creating and modifying test scripts.
‍

👉🏻Selenium Remote control :
Selenium RC acts as a central server, allowing you to write automated web application tests in any programming language with the help of client libraries. While each test run needs a separate port, only one RC server instance is required for Java/PHP tests.

👉🏻Selenium Web Driver :
Unlike its Selenium RC, Selenium WebDriver interacts directly with browsers, eliminating the need for a separate server. It supports popular browsers and even offers headless testing with HtmlUnit. Additionally, WebDriver leverages native OS functionalities for smoother execution and avoids compatibility issues.

👉🏻Selenium GRID :
Essentially, Selenium Grid is a central hub that manages multiple web browsers running on different machines. Its distributed testing power makes Selenium Grid a valuable tool for thorough and efficient web application testing. You can run your Selenium tests across these browsers in parallel, which reduces testing time and facilitates thorough cross-browser compatibility testing.

Advantages of using Selenium for Automation testing

In today's web development race, a flawless user experience is the winning ticket. Manual testing, though essential, can be slow and error-prone. That's where selenium software testing steps in - a powerful automation testing tool.

Here's what makes Selenium the go-to choice for testers:

Different Types of Testing Frameworks in Selenium

‍It might be difficult to choose the best framework among the many possibilities available. Let us examine the primary categories of Selenium frameworks to assist you in making a well-informed choice:

1. Prebuilt Data-Driven Testing Framework: This type of testing framework allows tests to be run with different data sets stored outside by keeping test data and scripts apart. This division allows for simple data adjustments without requiring rewriting of the code, keeping the tests flexible and clear.
   
   
2. Keyword-Driven Framework: Using action-based keywords, keyword-driven frameworks allow tests to be written in a legible manner for humans. Better cooperation is encouraged by this transparency, which improves communication between technical and non-technical teams.
   ‍
3. Hybrid Framework: Providing flexibility and adaptability, hybrid frameworks combine the advantages of data-driven and keyword-driven techniques. They enable a flexible testing approach that meets the needs of various testing situations and intricate project requirements.

‍

How do we select the right types of Frameworks in Selenium?

Choosing the appropriate Selenium framework requires taking into account a few crucial elements:

• Project Requirements: Recognize the testing requirements specific to your project, including cooperation, scalability, data variances, and complexity.
  
  
• Team Skills: Assess the proficiency of your group in several framework types, such as keyword-driven and data-driven methodologies.
  
  
• Test Objectives: To find the framework that best supports reaching your test objectives, clearly identify them.
  
  
• Application Complexity: Select a framework that can manage your web application's complexity after taking it into consideration.
  
  
• Community Support: Make sure the framework you select has a large and active community supporting it in case you need help, updates, or resources.

The different reporting frameworks used for Selenium tests

Reporting, which provides information on test execution and outcomes, is essential to Selenium test automation. To improve visibility and decision-making, let's examine some reporting formats frequently used with Selenium tests.

• TestNG Reports : TestNG Reports are structured HTML reports that show test grouping, status, and comprehensive test reports.
  
• ExtentReports : Comprehensive reporting that improves report readability with interactive HTML elements like test history, screenshots, and classification.
• Allure Framework: Multiple languages and frameworks are supported; user-friendly reports with comprehensive test procedures, attachments, and trend analysis are provided.
• ReportNG : ReportNG provides improved HTML reports with classification and statistics, using easily customizable themes for easy reading.
