java - testfx 未打印到标准输出

Question

我有一个简单的应用程序，如果用户单击登录按钮，消息被打印到标准输出。我正在尝试开始使用 testfx，但是当它模拟按钮单击时，没有打印任何消息。这是预期的行为，还是我遗漏了什么？

DialogioController.java:

package dialogio;

import java.net.URL;
import java.util.ResourceBundle;
import javafx.fxml.FXML;
import javafx.scene.control.ListView;
import javafx.scene.control.TabPane;
import javafx.scene.control.TextField;
import javafx.scene.input.MouseEvent;
import javafx.scene.control.Button;

public class DialogioController {

    @FXML
    private ResourceBundle resources;

    @FXML
    private URL location;

    @FXML
    private ListView<?> peopleList;

    @FXML
    private TabPane tabList;

    @FXML
    private TextField usernameField;

    @FXML
    private TextField passwordField;

    @FXML
    private TextField ipField;

    @FXML
    private Button loginButton;

    @FXML
    void login(MouseEvent e) {
        System.out.println("Trying to login!");
    }


    @FXML
    void initialize() {
        assert peopleList != null : "fx:id=\"peopleList\" was not injected: check your FXML file 'Dialogio.fxml'.";
        assert tabList != null : "fx:id=\"tabList\" was not injected: check your FXML file 'Dialogio.fxml'.";
        assert usernameField != null : "fx:id=\"usernameField\" was not injected: check your FXML file 'Dialogio.fxml'.";
        assert passwordField != null : "fx:id=\"passwordField\" was not injected: check your FXML file 'Dialogio.fxml'.";
        assert ipField != null : "fx:id=\"ipField\" was not injected: check your FXML file 'Dialogio.fxml'.";

    }
}

        click(loginButton);
    }
}
