PowerMock访问私人会员 [英] PowerMock access private members

问题描述

阅读后：
https://code.google.com/ p / powermock / wiki / BypassEncapsulation
i意识到，我不明白。

After reading: https://code.google.com/p/powermock/wiki/BypassEncapsulation i realized, i don't get it.

参见本例：

public class Bar{
   private Foo foo;

   public void initFoo(){
       foo = new Foo();
   }
}

如何访问私人会员 foo 使用PowerMock（例如，验证 foo 是否为空）？

How can i access the private member foo by using PowerMock (For example to verify that foois not null)?

注意：

我不想要的是用额外的修改代码方法。

编辑：

我意识到我错过了示例代码块带解决方案的链接页面。

I realized that i missed a sample code block on the linked page with the solution.

解决方案：

 Whitebox.getInternalState(bar, "foo");

推荐答案

这应该像编写以下测试类一样简单：

That should be as simple as writing the following test class:

public class BarTest {
    @Test
    public void testFooIsInitializedProperly() throws Exception {
        // Arrange
        Bar bar = new Bar();

        // Act
        bar.initFoo();

        // Assert
        Foo foo = Whitebox.getInternalState(bar, "foo");
        assertThat(foo, is(notNull(Foo.class)));
    }
}

添加正确（静态）导入保留为练习给读者：）。

Adding the right (static) imports is left as an exercise to the reader :).
