public class DecimalSliderTester<T extends DecimalSlider>
extends ComponentTester<T>

Tester for DecimalSlider components.

Simulates the user moving the slider handle in the browser: setting the value directly or incrementing/decrementing it by steps, with validation that the component is usable and the value stays within the min/max bounds and step alignment.

Before Vaadin 25.2 this class was named SliderTester. It was renamed without a deprecation cycle because the Slider component is experimental and behind a feature flag.

Since:

1.1
