The JavaFX CSS style "-fx-columns" is absent in the list of available styles for PasswordField/TextFields controls. So, tests are listed below failed by the reason:
openPage: page is null, probably not found.

It means either the style "-fx-columns" should be returned in the PasswordField/TextFields controls or these tests should be removed from FXCss test suite.
This issue is related on http://javafx-jira.kenai.com/browse/RT-16689

To check the style run:
package passwordboxesapp;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.PasswordField;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

/**
 *
 * @author Pavel Zernov
 */
public class PasswordBoxesApp extends Application {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        launch(args);
    }
    
    @Override
    public void start(Stage primaryStage) {
        PasswordField pswd = new PasswordField();
        pswd.setText("password");
        pswd.setFocusTraversable(false);
        pswd.setStyle("-fx-columns: 2;");
                       
        StackPane root = new StackPane();
        root.getChildren().add(pswd);
        primaryStage.setScene(new Scene(root, 200, 50));
        primaryStage.show();
    }
}
