What is IsDisplayed() in Selenium? Syntax and Working Explained

Imagine you are automating a test and need to make sure a button is visible before clicking it. So, how do you check? That's where Selenium's IsDisplayed flourish as a lifesaver! It’s the hidden asset that helps you confirm if web elements are visible and ready to interact. In this blog, we will analyse how IsDisplayed works while breaking down its syntax and show you real-world examples to ramp up your automation skills.

Understand What is Selenium?

Selenium is an open-source framework that is used to automate web browsers. It allows software testers to simulate real user interactions with websites, ensuring functionality and performance. With Selenium, you can automate tasks, ranging from filling out forms to navigating pages. One of the prerequisites to learn Selenium is a basic understanding of web technologies such as HTML and JavaScript.

The tool supports a wide range of Programming Languages, such as Python, Java and C#, and works across different browsers (Chrome, Firefox, and Safari). Here, Selenium WebDriver, the core component, interacts directly with browsers to control their actions.

For example,

This code opens a website, locates a login button, and clicks it automatically. Moreover, Selenium works to streamline web testing and helps ensure web applications work as expected.

What is Web Elements in Selenium?

Web elements in Selenium represent the webpage’s components, such as buttons, links, text fields, and images that can be interacted with during automated testing. These elements are identified using locators like ID, name, class, and XPath.

Selenium interacts with these elements through its WebDriver API, which allows users to perform actions like clicking, typing, or validating visibility. Hence, properly locating and manipulating these elements is essential for automating browser tasks and ensuring web applications work as expected.

What is isDisplayed Method in Selenium?

The isDisplayed in Selenium checks whether a web element is visible on a webpage or not. It returns a boolean value 'true' if the element is visible and 'false' if not. This method is crucial for ensuring elements are present and interactable during automated tests.

Syntax

Here, the element refers to the web element you want to check for visibility. The method returns ‘true’ if the element is displayed on the page and ‘false’ otherwise.

How to Use isDisplayed Method in Selenium?

To use isDisplayed, first locate the element using Selenium's WebDriver, then call the method to check its visibility. For example, if you want to verify if a button is visible on the page, you would use the following code snippet:

What is isEnabled Method in Selenium?

The isEnabled in Selenium determines whether a web element, such as a button or text field, is enabled or disabled. An element that is enabled can be interacted with (e.g., clicked or typed into), while a disabled element cannot be interacted with.

Syntax

Here, element refers to the web element being checked. If the element is enabled, isEnabled returns ‘true’, indicating that it can be interacted with. On the other hand, if the element is disabled, it returns ‘false’, meaning interaction is not possible. This method is important to validate the state of interactive elements in automated tests.

What is isSelected Method in Selenium?

The isSelected in Selenium is used to check whether a specific element, like a checkbox or radio button, is selected. It returns a boolean value 'true' if the element is selected, and 'false' if it's not. This method is often used for verifying whether a user has made a selection in forms or input fields.

Syntax

In this syntax, an element represents the web element (e.g., a checkbox or radio button). The method returns ‘true’ if the element is currently selected, otherwise, it returns ‘false’. This is crucial for validating user selections in automated tests.

Comparison Between isDisplayed, isSelected & isEnabled

The methods isDisplayed, isSelected, and isEnabled allow you to interact with and verify the state of web elements during automation, ensuring that the elements behave as expected. Their brief comparison is stated below:

1) isDisplayed checks if an element is visible on the page. It returns to true if the element is visible and false if it is not.

2) isSelected checks whether elements like checkboxes or radio buttons are selected. It returns true if selected and false if not.

3) isEnabled determines if an element is enabled (clickable or interactable). It returns `true` if the element is enabled and 'false' if it is disabled.

Each of these methods serves a specific role in web testing, helping ensure that the web elements behave as expected during automation. The key difference lies in what aspect of the element they validate: visibility, selection state, or interactivity.

Conclusion

We hope you understand this brief overview on isDisplayed in Selenium. Mastering the isDisplayed in Selenium is important to ensure that web elements are visible and interactable during automated testing. Incorporating Synchronization in Selenium WebDriver is essential in conjunction with the isDisplayed function to guarantee that elements are fully loaded before performing checks.
