[英]How to mock method from other class in a loop using PowerMock?
我有一个待测试的公共无效方法“ a”,在“ a”中,我有一个以字符串为迭代器的循环,在此循环中,我以字符串迭代器为参数调用了B的公共无效方法,我想模拟它,我想编写一个使用PowerMock来测试“ a”的单元测试,如何实现这个目标?
您在方法“ a”中是否有任何静态方法引用,如果不直接使用Mockito,则PowerMock通常用于存根静态方法,模拟私有变量,构造函数等。我希望您不进行集成测试,所以只准备模拟类B的方法,然后使用Mockito.verify方法检查您的方法是否被实际调用。 请参阅下面的答案。
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.Mockito;
import org.mockito.junit.MockitoJUnitRunner;
@RunWith(MockitoJUnitRunner.class)
public class ClassATest {
@InjectMocks
ClassA classsA;
@Mock
ClassB classB;
@Test
public void testClassAMethod() {
//Assuming ClassA has one method which takes String array,
String[] inputStrings = {"A", "B", "C"};
//when you call classAMethod, it intern calls getClassMethod(String input)
classA.classAMethod(inputStrings);
//times(0) tells you method getClassBmethod(anyString()) been called zero times, in my example inputStrings length is three,
//it will be called thrice
//Mockito.verify(classB, times(0)).getClassBMethod(anyString());
Mockito.verify(classB, times(3)).getClassBMethod(anyString());
}
