TimePickerElement

Full API (methods, signatures, descriptions): see api-reference.md. This note covers only behaviour that isn't obvious from the signatures.

String values use HH:mm, LocalTime is set directly

setValue(String) (inherited from HasInputFieldElement) / assertValue(String) expect the HH:mm display format (e.g. "09:00"), while setValue(LocalTime) sets the value directly. Pick the overload matching your format.

Asserting a cleared value

After clearing, assert emptiness with the LocalTime overload passing an explicit null cast:

time.clickClearButton();
time.assertValue((LocalTime) null);
