【问题描述】:
我被困在一个非常奇怪的案例中。 我有一些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!");
}
}
我也有一个子类:
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);
}
}
我需要用测试覆盖子类。
我尝试了很多与 PowerMockito 的组合, 但他们都不能验证父类的受保护方法的调用。 另外,我限制只能使用 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
如果我将这段代码添加到 然后 部分
Mockito.verify(aSpy, times(3)).mainMethod(100500);
Mockito.verify(aSpy, times(1)).generifiedMethod("abc", 100);
Mockito.verify(aSpy, times(1)).method(250);
它给了我以下错误信息:
Wanted but not invoked:
a.generifiedMethod("abc", 100);
【问题讨论】:
-
添加
Mockito.verify(aSpy, times(3)).mainMethod(100500);会产生编译错误,因为mainMethod()是protected!
