### Question:
PanLine extends JPanel { public String getAlign() { EnumAlign enumAlign = (EnumAlign) comboBoxAlign.getSelectedItem(); return enumAlign.getXmlValue(); } PanLine(); String getAlign(); String getThickness(); String getCustomWidth(); String getCustomWidthUnit(); String getColor(); void setAlign(EnumAlign enumAlign); void setThickness(String thickness); void setCustomWidth(String width); void setCustomWidthUnit(EnumWidthUnit enumWidthUnit); void setColor(String hexValue);  }### Answer:
@Test public void testGetAlign() { JComboBox comboBox = new JComboBox(); for (EnumAlign enumAlign : EnumAlign.values()) { comboBox.addItem(enumAlign); } comboBox.setSelectedIndex(1); Whitebox.setInternalState(panLine, "comboBoxAlign", comboBox); String align = panLine.getAlign(); String expectedAlign = EnumAlign.values()[1].getXmlValue(); assertEquals(expectedAlign, align); }
