Я хочу сделать утверждение, что компонент рендеринга моей таблицы имеет ожидаемую всплывающую подсказку.class GuiCheckBoxCellRendererTest extends SwingTest {
JFrame frame;
@AfterEach
void tearDown() {
runAndWait(frame::dispose);
}
@Test
void getTableCellRendererComponent_givenValue_returnsExpectedCheckBox() {
String tooltip = "Some tooltip";
CheckBoxCellRenderer renderer = callAndWait(() -> CheckBoxCellRenderer.from(tooltip));
DefaultTableModel tableModel = callAndWait(() -> new DefaultTableModel(new Object[][]{{1, "Alex"}}, new String[]{"Status", "Name"}));
table = callAndWait(() -> new JTable(tableModel));
runAndWait(() -> table.setDefaultRenderer(Object.class, renderer));
frame = createFrame(table);
robot.showWindow(frame);
robot.focusAndWaitForFocusGain(frame);
assumeThat(callAndWait(frame::isVisible)).isTrue();
assumeThat(callAndWait(frame::isShowing)).isTrue();
assumeThat(callAndWait(table::isVisible)).isTrue();
assumeThat(callAndWait(table::isShowing)).isTrue();
JTableFixture tableFixture = new JTableFixture(robot, table);
tableFixture.cell(TableCell.row(0).column(0)).select();
robot.waitForIdle();
tableFixture.requireToolTip(tooltip); // requires tooltip for the entire table, apparently
}
JFrame createFrame(JComponent component) {
return callAndWait(() -> {
JFrame frame = new JFrame();
JScrollPane scrollPane = new JScrollPane(component);
scrollPane.setPreferredSize(new Dimension(200, 150));
frame.add(scrollPane);
frame.pack();
return frame;
});
}
}
