Selenium has always been the top choice for anybody who is thinking about automation testing. It is the favourite choice of developers and testers overall. But why do you think there is so much hype around Selenium when there another available toolset? And, surprisingly most of these tools give almost the same results.
Let us begin by stating,
What is Selenium?
Now, before we actually move on to address why Selenium has taken precedence over all other automation tools, let us seek to find out what it exactly is. Well, Selenium is basically is an open-source tool for automation testing that is being carried out on varied web browsers. It is endowed with four different tools that help it handle the diverse needs of different organizations. These tools are:
- Selenium RC
- Selenium Integrated Development Environment
- Selenium Grid
- Selenium WebDriver
The last two have been merged these days.
Coming back to the main question-
Why is Selenium so important?
Selenium gained prominence over other automation testing tools because it comes endowed with the following benefits.
- Language and Framework Support
- Multi-Browser Support
- Support Across Operating Systems
- Easy Implementation
What are the Elements used in Selenium?
The elements are an important part of everything abstract. Web elements are basica is present on the web page. For instance, the text box, button, etc. The WebElement shows the HTML element. The elements can be divided into different categories:
- Edit Box: This is an elementary text control that lets a user type a small amount of text.
- Link: This is also called the hyperlink. It is helpful in connecting one web page to another. The user is able to move from one page to another via a simple click.
- Button: This refers to a button that is clickable. It is used in both the forms and places in the document that requires a simple, and standard button functionality.
- Image: It helps in carrying out various actions in the images just like clicking on the image link or the image button.
- Text Area: This element is used for an inline element that is used for the designation of plain-text editing control that contains more than one line.
- CheckBox: This is basically a text box that has a small interactive box that has the option of being toggled by the user for either indicating an affirmative or a negative choice.
- Radio Button: This button is optional and comes with a graphical control element. It lets the user pick only one of the predefined set of options that are mutually exclusive.
- Dropdown List: This is basically a graphical control element that is quite similar to the list box. It allows the user to pick one value from the list. When this drop-down list is inactive only a single element is displayed.
This was a list of the Webelements in Selenium. Now, here let’s also discuss the various operations that can be performed on these.
List of Operations Performed on WebElements
These operations are to be performed on the WebElements in order to access them. These operations are started with the browser actions until these are performed on the frames. Let us see them in detail:
- Operations to be Performed on Browser: The operations involve launching the browser and then navigating to the specific web page. Then you need to close the current browser, followed by closing all the browsers that have been opened by the WebDriver during execution. You can also maximize the browser and then refresh the same.
- Operations to be Performed on Web Page: These just involve getting the title of the page and also its URL.
- Operations to be Performed on Edit Box: The operations involve entering, getting and clearing the value.
- Operations to be Performed on Link: The operations usually involve clicking on the link and returning its name.
- Operations for Button: The operations involve enabling the click and also displaying its status.
- Operations on Image: There are many operations that can be performed on the image. For a general image, it requires no functionality, while an image button requires a click and the image link redirects it to another page.
- Operations on Text Area: It helps in returning or capturing the message from the web page.
- Operations on Radio Button: The operations involve the selection of the radio button and then checking if the same has been selected or not.
- Operations on Drop Down: This hovers around the selection of an item on the list and then finally getting the item count.
- Operations on Frame: The operations involve switching from a top window to the specific frame on the web page and also switching to a frame to top window.
It is also important to know about how to locate the elements on the web page.
Location of Web Elements on the Page
Selenium has different types of locators for the correct identification of web elements. These are:
- ID locator: ID is considered as the most important way for identification of web elements. IDs are considered as the safest locator options and are seen as the top priority.
- Name locator: Again a highly effective way to locate an element that has the same attribute. In this strategy, the first element with the same value as the name attribute is returned.
- linkText & Partial linkText: Hyperlinks can be identified on a webpage using this. It is determined with the help of an anchor tag (<a>). Anchor tags are usually followed by the link text for the creation of hyperlinks.
- CSS Selector: This is used for providing style rules for various web pages and also for the identification of one or more elements on the web page. It is considered the best way for the location of elements on the web page.
- XPath: It is a language for querying the XML documents. It consists of path expression along with some other conditions.
Selenium is definitely the preferred choice of most automation engineers for the diverse set of uses and functionalities. It is important to have accurate and appropriate knowledge of the same. We have tried to include most aspects of the web elements of selenium so you have a comprehensive view of the same.
