​
Overview

HasValueElement is a mixin interface for Vaadin components that expose a textual value through an input slot. This interface provides methods to get, set, clear, and assert input values.

​
Methods

​
getInputLocator

default Locator getInputLocator()
Returns the locator for the native input element inside the component. Returns: Locator for the element with slot="input" attribute

​
getValue

default String getValue()
Gets the current string value of the input field. Returns: The current value as a string

​
setValue

default void setValue(String value)
Sets the field value by filling the input and dispatching a change event.
​
value
String
The value to set in the input field

​
clear

default void clear()
Clears the input value by setting it to an empty string.

​
assertValue

default void assertValue(String value)
Asserts that the input value matches the expected string using Playwright assertions.
​
value
String
The expected value to assert against

​
Implementation Details

This interface extends HasLocatorElement and provides default implementations for all methods. The value operations work on the input slot element, which is located using *[slot="input"]. The setValue() method not only fills the input but also dispatches a change event to ensure that client-side listeners are triggered.

​
Implementing Classes

This interface is implemented through HasInputFieldElement, which is used by:
  • TextFieldElement (and its subclasses like EmailFieldElement, PasswordFieldElement, etc.)
  • AbstractNumberFieldElement (and its subclasses like IntegerFieldElement, NumberFieldElement)
  • BigDecimalFieldElement
  • ComboBoxElement
  • MultiSelectComboBoxElement
  • SelectElement
  • DatePickerElement
  • DateTimePickerElement
  • TimePickerElement

​
Usage Example

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

// Get a text field by label
TextFieldElement nameField = TextFieldElement.getByLabel(page, "Name");

// Set a value
nameField.setValue("John Doe");

// Get the current value
String currentValue = nameField.getValue();

// Assert the value
nameField.assertValue("John Doe");

// Clear the field
nameField.clear();
nameField.assertValue("");
