我陷入了一个非常奇怪的情况.
我有一些我需要测试的特定代码.
这里是:
public class A {
/*
* The real method of real class is so big that I just don't want to test it.
* That's why I use throwing an exception.
*/
protected void method(Integer result) {
throw new RuntimeException("Oops!");
}
protected <T> T generifiedMethod(String s, T type) {
throw new RuntimeException("Oops!");
}
protected void mainMethod(Integer value) {
throw new RuntimeException("Oops!");
}
}
我也有一个孩子班:
public class B extends A {
@Override
protected void mainMethod(Integer value) {
if (value == 100500) {
Integer result = super.generifiedMethod("abc", 100);
super.method(result);
}
super.mainMethod(value);
}
}
我需要通过测试来覆盖孩子班.
我正在尝试与PowerMockito进行很多组合,
但是它们都不能验证对父类的受保护方法的调用.
另外,我限制使用Mockito,PowerMockito和TestNG.
这是我的测试代码(变体之一):
@Test
public void should_invoke_parent_logic_methods_of_A_class() throws Exception {
/* Given */
A aSpy = PowerMockito.spy(new A());
PowerMockito.doReturn(250).when(aSpy, "generifiedMethod", "abc", 100);
PowerMockito.doNothing().when(aSpy, "method", 250);
PowerMockito.suppress(method(A.class, "mainMethod", Integer.class));
/* When */
aSpy.mainMethod(100500);
/* Then */
/**
* Here I need to verify invocation of all methods of class A (generifiedMethod(), method(),
* and mainMethod()). But I don't need them to be invoked because their logic is unwanted
* to be tested in case of tests for class B.
*/
}
对于如何测试B类的任何建议,我将不胜感激.谢谢.
更新
如果我添加到Then部分这段代码
Mockito.verify(aSpy, times(3)).mainMethod(100500);
Mockito.verify(aSpy, times(1)).generifiedMethod("abc", 100);
Mockito.verify(aSpy, times(1)).method(250);
它给我以下错误消息:
Wanted but not invoked:
a.generifiedMethod("abc", 100);
最佳答案 您是否考虑使用variant来更改类的设计并使用组合而不是继承?
然后,您将能够模拟/侦察A类的实例并将其注入到B类的实例中.
在这种情况下,您将能够配置您需要的任何行为.
我真的不确定doCallRealMethod()会为你制作技巧,因为你可以选择模拟方法或调用实际方法,但不能同时使用.
