Product

KDS.

Desired behavior

We should add unit tests to KListWithOverflow, since it has some complicated calculations and needs to be protected from regressions. So we need to test at least the following things:

• It should render the whole list items if it fits in the available space, even if there is just 1px of difference.
• It shouldnt render the more slot if the list items fits in the available space.
• It shouldnt render the items that are overflowed and dont fit in the available space even if there is just 1px of difference.
• It should render the more slot if there are overflowed items.
• It should pass the correct items in the overflowItems array passed to the more slot.
• It shouldnt render a divider as the last item in the visible list, even if it fits in the available space.

Current behavior

We currently dont have unit tests for KListWithOverflow.
