文件src/main/resources/core/mainWindow.fxml的详细信息并不重要,但下面是一个示例:

<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.layout.VBox?>
<VBox prefHeight="600.0" prefWidth="900.0" xmlns="http://javafx.com/javafx/11.0.1"
      xmlns:fx="http://javafx.com/fxml/1" fx:controller="core.FXMLController" >
    <children>
        <Label text="Some label"></Label>
    </children>
</VBox>

上述测试失败。调用实际方法
Stage.show()
,忽略它是模拟的事实。
如果我将其从
Mock
更改为
GroovyMock
则使用Mock方法
show()
,测试通过。

为什么一个普通的Spock
Mock
会被忽略?

普通Java
Mock
s不能模拟final方法,根据
阶段。show
是final
GroovyMock
s通过使用groovy MOP工作,因此只有在从groovy代码调用时才能工作,但在这方面它们更强大。

普通Java
Mock
s不能模拟最终方法,根据
阶段。show
是最终的
GroovyMock
s通过使用groovy MOP工作,因此只有在从groovy代码调用时才能工作,但它们在这方面更强大。

Duh!因为它是
最终版本
。谈论一个“小学生的错误”。。。谢谢!;-)我只是想写同样的答案,因为昨天晚上我很忙。我在OP的测试中添加了这一行以进行说明:
println“modifiers=“+java.lang.reflect.Modifier.toString(Stage.getDeclaredMethod(“show”).modifiers)
。输出将是:
modifiers=public final
