为没有参数的受保护的void方法编写Junit

Question

Write a Junit test case for a protected void method without arguments, which does nothing.

protected void init() {
    i=10;
    j=20;
}

Now, I want to write a Junit for init() method which does nothing apart from initialization. Any help is appreciated. Thanks in advance.

If you want to check that the fields are set after the initialization you do exactly that.

@Test
public void fieldAreInitialized()
{
    YourClass x = new YourClass();
    x.methodWhichCallsInit();

    Assert.assertEquals(10, x.getI());
    Assert.assertEquals(20, x.getJ());
}
