How to Write a Mouse Hover Test Script Using Selenium and Page Object Model (POM)

To write a test script for mouse hovering in a web page using Page Object Model (POM) with Selenium, you'll follow a set of steps that ensure your automation is efficient, maintainable, and easy to understand. In this article, we'll guide you through creating a test script for mouse hovering, from setting up your project to writing the actual test cases.

1. Setting Up Your Project

Before you start writing your test script, ensure that you have a Selenium project set up with the necessary dependencies. Here is a basic setup for a Maven project:

dependencies
    dependency
        
        artifactIdselenium-java/artifactId
        version4.x.x/version      !-- Replace with the latest version --
    /dependency
    dependency
        groupIdorg.testng/groupId
        artifactIdtestng/artifactId
        version7.x.x/version      !-- Replace with the latest version --
        scopetest/scope
    /dependency
/dependencies

Make sure to include the latest versions of Selenium and TestNG in your project.

2. Creating Page Object Classes

In the Page Object Model, each page of your application is represented as a class, with methods to interact with that page. Here is an example of a Page Object class for a web page with a hoverable element:

import ;
import ;
import ;
public class HoverPage {
    private WebDriver driver;
    private By hoverElement  (hoverableId);
    private By tooltipElement  (tooltipId);
    public HoverPage(WebDriver driver) {
          driver;
    }
    public void hoverOverElement() {
        new Actions(driver).moveToElement((hoverElement)).build().perform();
    }
    public String getTooltipText() {
        String tooltipText  (tooltipElement).getText();
        return tooltipText;
    }
}

In this example, hoverElement is the element that the mouse should hover over, and tooltipElement is the element that displays the tooltip text after hovering.

3. Writing Test Cases

The test cases for mouse hovering should be written using a testing framework such as JUnit or TestNG. Here’s an example of a test case that uses the page object class created above:

import ;
import ;
import ;
import ;
import ;
import ;
public class HoverTest {
    private WebDriver driver;
    private HoverPage hoverPage;
    @BeforeClass
    public void setUp() {
        // Set up the ChromeDriver and initialize the driver
        (, path/to/chromedriver);
        driver  new ChromeDriver();
        // Navigate to the web page with hoverable elements
        ();
        hoverPage  new HoverPage(driver);
    }
    @Test
    public void testMouseHover() {
        hoverPage.hoverOverElement();
        String tooltipText  ();
        (Expected Tooltip Text, tooltipText); // Replace with the expected tooltip text
    }
    @AfterClass
    public void tearDown() {
        if (driver ! null) {
            driver.quit();
        }
    }
}

In this example, the HoneTest class sets up the WebDriver, initializes the HoverPage object, and defines a test method testMouseHover that performs the hover action and checks the tooltip text for match with the expected value.

Running the Test

To run the test, use your preferred Integrated Development Environment (IDE) or build tool that supports TestNG or JUnit. This approach provides a basic structure for mouse hovering testing using Selenium and Page Object Model (POM). You should adjust the locators and expected values according to your specific application under test.

By following these steps and best practices, you can build robust and maintainable test scripts that effectively cover your web application's mouse hover functionality.
