Input Simulators

Input Simulators

HeadlessTestingFramework offers both low-level and high-level input entry points.

Touch

Avalonia.HeadlessTestingFramework.TouchInputSimulator is the lowest-level API and exposes direct touch lifecycle methods:

  • TouchDown(...)
  • TouchMove(...)
  • TouchUp(...)
  • Tap(...)
  • DoubleTap(...)
  • Swipe(...)
  • SimulatePinchZoom(...)
  • SimulateTwoFingerPan(...)

Use it when precise control over positions and timing matters.

Keyboard

Avalonia.HeadlessTestingFramework.KeyboardInputSimulator covers individual keys, text typing, modifiers, and convenience shortcuts such as:

  • CtrlKey(...)
  • Copy(...)
  • Paste(...)
  • SelectAll(...)
  • ArrowUp() through ArrowRight()

Mouse

Avalonia.HeadlessTestingFramework.MouseInputSimulator is the direct path for click, drag, and wheel scenarios where pointer semantics matter more than touch semantics.

Gesture Level APIs

Avalonia.HeadlessTestingFramework.GestureSimulator raises higher-level gesture events, while Avalonia.HeadlessTestingFramework.MultiTouchTestHelperFactory helps trigger recognizer-based pinch, pan, and rotation flows.

Recommended Usage
