I am trying to get information from inside a void actionEvent so I can use it for JUnit test ( first time trying to use JUnit ). But i am not sure how to do this. If anyone can throw some guidance, i would appreciate it.
Here is my code below. (this code it just to use with test with JUnit, i know its garbage sauce.

import java.awt.Container;
import javax.swing.JTextField;

得分: 1

我发现，与其尝试这样做，将ActionEvent从按钮点击转换为auth会更容易。就像这样。

btnLogout.setOnAction((ActionEvent e) -> {
    doLogin();
});

然后将其他所有内容放在doLogin中。
@Spindoctor的答案也不错，应该予以考虑。

英文:

I found instead of trying to do this, its easier to cast the ActionEvent's from the button click to the auth. Such as this.

btnLogout.setOnAction((ActionEvent e) -> {
doLogin();
});

and put everything else in the doLogin.
@Spindoctor s answer is good though and should be counted.
