HasSuffixElement

Interface for Vaadin components that support suffix slot content

Overview

HasSuffixElement provides utilities to interact with Vaadin components that implement the HasSuffix interface, which allows placing content in a suffix slot. The suffix typically appears at the end of the component, after the main input or content area.

This mixin interface extends HasLocatorElement and provides default implementations for accessing, reading, and asserting suffix slot content.

Interface

public interface HasSuffixElement extends HasLocatorElement {
    default Locator getSuffixLocator() { ... }
    default String getSuffixText() { ... }
    default void assertSuffixHasText(String text) { ... }
}

Methods

getSuffixLocator()

Returns a locator for the suffix slot content.

default Locator getSuffixLocator()

Returns: Locator targeting the first element with slot="suffix"

Implementation:

return getLocator().locator("*[slot=\"suffix\"]").first();

---

getSuffixText()

Retrieves the text content of the suffix slot.

default String getSuffixText()

Returns: The text content of the suffix element

---

assertSuffixHasText()

Asserts that the suffix slot has the expected text, or is hidden when null.

default void assertSuffixHasText(String text)

text · String

Expected text content of the suffix. If null, asserts that the suffix is not visible.

Behavior:

• If text is non-null: Asserts the suffix has exactly that text
• If text is null: Asserts the suffix is not visible

Implementing Classes

The following element classes implement HasSuffixElement:

• TextFieldElement - Text input fields
• BigDecimalFieldElement - Decimal number fields
• AbstractNumberFieldElement - Base class for number fields
• ButtonElement - Action buttons
• SideNavigationItemElement - Navigation items

Usage Examples

Basic Suffix Access

import com.microsoft.playwright.Page;
import org.vaadin.addons.dramafinder.element.TextFieldElement;

public class SuffixExample {
    public void testSuffixContent(Page page) {
        TextFieldElement weightField = TextFieldElement.getByLabel(page, "Weight");
        
        // Get the suffix text (e.g., "kg" unit)
        String suffixText = weightField.getSuffixText();
        System.out.println("Unit: " + suffixText);
        
        // Assert the suffix displays the expected unit
        weightField.assertSuffixHasText("kg");
    }
}

Custom Suffix Interactions

public class CustomSuffixExample {
    public void clickSuffixIcon(Page page) {
        TextFieldElement passwordField = TextFieldElement.getByLabel(page, "Password");
        
        // Access the suffix locator for custom interactions
        Locator suffixIcon = passwordField.getSuffixLocator();
        
        // Click on an interactive suffix element (e.g., show/hide password icon)
        suffixIcon.click();
    }
}

Asserting Suffix Visibility

public class SuffixVisibilityExample {
    public void testSuffixVisibility(Page page) {
        TextFieldElement temperatureField = TextFieldElement.getByLabel(page, "Temperature");
        
        // Assert suffix is present with text
        temperatureField.assertSuffixHasText("°C");
        
        // After changing settings, assert new suffix
        // (e.g., user switches to Fahrenheit)
        temperatureField.assertSuffixHasText("°F");
    }
}

Integration Test Example

import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assertions.*;

public class TextFieldSuffixIT {
    @Test
    public void shouldDisplayPercentageSuffix() {
        TextFieldElement discountField = TextFieldElement.getByLabel(page, "Discount");
        
        // Verify the percentage symbol appears as a suffix
        assertEquals("%", discountField.getSuffixText());
        
        // Assert using the built-in assertion method
        discountField.assertSuffixHasText("%");
    }
    
    @Test
    public void shouldHideSuffixWhenNotSet() {
        TextFieldElement plainField = TextFieldElement.getByLabel(page, "Plain Input");
        
        // Assert no suffix is visible
        plainField.assertSuffixHasText(null);
    }
    
    @Test
    public void shouldInteractWithSuffixButton() {
        TextFieldElement searchField = TextFieldElement.getByLabel(page, "Search");
        
        // Click the search button in the suffix slot
        searchField.getSuffixLocator().click();
        
        // Verify search was triggered
        // ... additional assertions
    }
}

Button with Suffix Example

import org.vaadin.addons.dramafinder.element.ButtonElement;

public class ButtonSuffixExample {
    public void testButtonWithIcon(Page page) {
        ButtonElement submitButton = ButtonElement.getByText(page, "Submit");
        
        // Check if button has an icon in the suffix slot
        String suffixContent = submitButton.getSuffixText();
        
        // For icon buttons, you might want to check the locator directly
        Locator iconLocator = submitButton.getSuffixLocator();
        boolean hasIcon = iconLocator.count() > 0;
    }
}
