/**

 * </p>
 *
 * <pre>
 * JFileChooserFixture fileChooser = JFileChooserFinder.findFileChooser().using(robot);
 * </pre>
 *
 * <p>
 * Where {@code robot} is an instance of {@link org.assertj.swing.core.Robot}.

 * <p>
 * This example shows how to find a {@code JFileChooser} by type using a lookup time of 10 seconds:
 * </p>
 *
 * <pre>
 * JFileChooserFixture fileChooser = JFileChooserFinder.findFileChooser().withTimeout(10000).using(robot);
 * </pre>
 *
 * <p>
 * We can also specify the time unit:
