Tests

To verify that your stylus app provides a differentiated experience, complete the following tests.

Stylus

Test ID Guideline IDs Description
T-Stylus_Draw_Write Stylus_Draw_Write Draw and write within the app using a stylus. Erase drawings and writing using the stylus.
T-Stylus_Drag_Drop Stylus_Drag_Drop Using a stylus, drag and drop content on drop targets within the app. In multi-window mode, drag and drop content between the app and another app (to and from both apps).
T-Stylus_Enhanced Stylus_Enhanced

Interact with the app using a stylus as follows:

  • As you draw, observe the latency between the current stylus position and the last rendered stroke.
  • Draw with varying amounts of stylus pressure. Check whether the width of the strokes changes as the pressure changes. More pressure should produce thicker strokes.
  • Tilt the stylus as you draw; shading strokes should be produced. The more the stylus is tilted, the wider and lighter the shading strokes should be.
  • Let your fingers and palm touch the screen as you draw. The finger and palm touches shouldn't produce marks.
