Locate elements By Tagname in Selenium Webdriver

Overview

In this tutorial, we will learn how to locate elements using By Tagname in Selenium Webdriver automation scripts. Using TagName is very generic and may result in one or more web elements for a particular tag. Example use case where this method is useful, is when we want to count rows in a table using tag <tr>.

Example:

List<WebElement> rows = htmlTable.findElements(By.tagName(“tr”));

For example, if we are testing the number of rows than we can assert with rows.size()

Sample Test to Count <input> tags

In this example, we will count the number of input tag elements on the TestLink Login page.
