Introduction

Selenium is an open-source automated testing framework used for web application testing. It is a popular tool among software testers and developers for testing web applications across different browsers. It has a wide range of features that make it a preferred choice for web application testing. One of the key features of Selenium is its ability to locate web elements on a web page. This is done by using locators. In this article, we will discuss the eight locators in Selenium that can be used to locate web elements on a web page.

What are Locators?

Locators are used to identify and locate web elements on a web page. They are used to find the HTML elements on a web page so that they can be interacted with. Locators are used in Selenium to locate web elements such as buttons, links, text boxes, etc. They are also used to identify elements on a web page that can be interacted with, such as links, buttons, and text boxes.

Types of Locators in Selenium

There are eight types of locators in Selenium that can be used to locate web elements on a web page. These are:

By CSS ID
By CSS Class Name
By Name Attribute
By DOM Structure or Xpath
By Tag Name
By Link Text
By Partial Link Text
By CSS Selector

By CSS ID

The By CSS ID locator is used to locate web elements on a web page by their ID attribute. The ID attribute is a unique identifier for an element on a web page. The By CSS ID locator is used to locate an element on a web page by its ID attribute. It is used in the following syntax:

find_element_by_id(“id_name”)

By CSS Class Name

The By CSS Class Name locator is used to locate web elements on a web page by their class name. The class name is an attribute of an element on a web page that is used to identify the element. The By CSS Class Name locator is used to locate an element on a web page by its class name. It is used in the following syntax:

find_element_by_class_name(“class_name”)

By Name Attribute

The By Name Attribute locator is used to locate web elements on a web page by their name attribute. The name attribute is an attribute of an element on a web page that is used to identify the element. The By Name Attribute locator is used to locate an element on a web page by its name attribute. It is used in the following syntax:

find_element_by_name(“name_attribute”)

By DOM Structure or Xpath

The By DOM Structure or Xpath locator is used to locate web elements on a web page by their DOM structure or Xpath. The DOM structure is the structure of the HTML document that is used to identify elements on a web page. The Xpath is an expression that is used to locate elements on a web page. The By DOM Structure or Xpath locator is used to locate an element on a web page by its DOM structure or Xpath. It is used in the following syntax:

find_element_by_xpath(“xpath_expression”)

By Tag Name

The By Tag Name locator is used to locate web elements on a web page by their tag name. The tag name is an attribute of an element on a web page that is used to identify the element. The By Tag Name locator is used to locate an element on a web page by its tag name. It is used in the following syntax:

find_element_by_tag_name(“tag_name”)

By Link Text

The By Link Text locator is used to locate web elements on a web page by their link text. The link text is the text of a link on a web page that is used to identify the link. The By Link Text locator is used to locate an element on a web page by its link text. It is used in the following syntax:

find_element_by_link_text(“link_text”)

By Partial Link Text

The By Partial Link Text locator is used to locate web elements on a web page by their partial link text. The partial link text is the text of a link on a web page that is used to identify the link. The By Partial Link Text locator is used to locate an element on a web page by its partial link text. It is used in the following syntax:

find_element_by_partial_link_text(“partial_link_text”)

By CSS Selector

The By CSS Selector locator is used to locate web elements on a web page by their CSS selector. The CSS selector is an expression that is used to identify elements on a web page. The By CSS Selector locator is used to locate an element on a web page by its CSS selector. It is used in the following syntax:

find_element_by_css_selector(“css_selector”)

Conclusion

In conclusion, the eight locators in Selenium are By CSS ID, By CSS Class Name, By Name Attribute, By DOM Structure or Xpath, By Tag Name, By Link Text, By Partial Link Text, and By CSS Selector. These locators are used to locate web elements on a web page so that they can be interacted with. They are essential for web application testing with Selenium.
