Question

Accepted Answer

Selenium components include Selenium IDE, Selenium RC, Selenium WebDriver. Different locators are ID, Name, Class Name, Tag Name, Link Text, Partial Link Text, CSS Selector and XPath. Selenium WebDriver is a tool used to automate web application testing. XPath is a language used to navigate through XML documents and web pages.

Accepted Answer

1.Selenium components are : Selenium IDE , Selenium WebDriver , Selenium Grid , Selenium RC (deprecated)

2. Locators are a way of identifying web elements on a web page for selenium to operate on : 
Xpath , id , name , classname, CSSSelector, Link Text, Partial link text, Tagname

3. Selenium webdriver is a component of Selenium which uses browser's native methods to automate web application.
4. //tagname[@ttribute='value']

Accepted Answer

Selenium WebDriver:

Selenium WebDriver is the core component of the Selenium framework. It provides a programming interface to interact with web browsers. WebDriver allows you to write scripts in various programming languages (Java, Python, C#, etc.) to automate browser actions. With WebDriver, you can open a browser, navigate to web pages, interact with elements (clicking buttons, typing text, etc.), and perform various other actions required for testing or automation.

XPath Example:

XPath (XML Path Language) is a powerful tool for selecting elements in an XML document (which includes HTML documents). Here's an example of an XPath expression to locate an element with a specific attribute value:

Suppose you want to locate an input element with the attribute id having the value "username" on a web page. The XPath expression would be:

//input[@id='username']

Selenium Components:

Selenium is a popular open-source automated testing framework primarily used for automating web applications for testing purposes, but it can also be used for various other tasks such as web scraping and automating repetitive tasks on websites. The main components of Selenium are:

1. Selenium WebDriver: This component provides a programming interface to control browsers programmatically. It allows you to simulate user interactions like clicking, typing, and navigating through web pages.

2. Selenium IDE (Integrated Development Environment): This is a record-and-playback tool that allows testers to record their interactions with the website and generate test scripts. However, it's not as powerful or flexible as WebDriver and is generally used for simple tasks.

3. Selenium Grid: Selenium Grid allows you to run your tests on multiple machines in parallel, enabling you to run tests on different browsers and operating systems simultaneously.

4. Selenium Remote Control (RC): This is the older version of Selenium that has been deprecated in favor of WebDriver. It allows you to control the browser remotely but is less efficient and versatile compared to WebDriver.

Different Locators in Selenium:

Locators are used to identify and locate elements on a web page. Selenium provides several locators to find elements:

1. ID: Locates an element by its unique HTML ID attribute.

2. Name: Finds an element by its "name" attribute.

3. Class Name: Locates elements by their CSS class name.

4. Tag Name: Finds elements by their HTML tag name.

5. Link Text: Locates hyperlinks with the exact text.

6. Partial Link Text: Locates hyperlinks with partial text.

7. XPath: XPath is a powerful language for locating elements based on their XML path in the HTML structure.

8. CSS Selector: Locates elements using CSS selectors.

Accepted Answer

Selenium IDE.

Selenium RC.

Selenium WebDriver.

Selenium Grid.

By.By CSS ID: find_element_by_id.

By CSS class name: find_element_by_class_name.

By name attribute: find_element_by_name.

By DOM structure or Xpath: find_element_by_xpath.

by tagName: find_element_by_tag_name()

By link text: find_element_by_link_text.Selenium WebDriver is a web framework that permits you to execute cross-browser tests. This tool is used for automating web-based application testing to verify that it performs expectedly. Selenium WebDriver allows you to choose a programming language to create test scripts.

Use Ctrl+F to write XPath in the elements tab, as shown below. As seen above, a simple XPath is used to locate the firstName tab. Based on the XPath syntax, first use // which means anywhere in the document. Here, input is the tag name that has an id attribute with the value “usernamereg-firstname”
