wondering a bit about this complicated test setup .. are you aware of the
VirtualFlowTestUtils (in test.something.infrastructure)? Using it, a test would
shrink down to something like:
@Test
public void testRemoveColumnsFixed() {
tableView.setFixedCellSize(20);
tableView.getColumns().remove(0, 2);
Toolkit.getToolkit().firePulse();
assertEquals(tableView.getVisibleLeafColumns().size(),
VirtualFlowTestUtils.getCell(tableView,
0).getChildrenUnmodifiable().size());
}
Or what am I missing?
