这是测试:
import static junit.framework.Assert.assertTrue;
import static org.powermock.api.mockito.PowerMockito.mock;
import static org.powermock.api.mockito.PowerMockito.whenNew;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
@RunWith(PowerMockRunner.class)
@PrepareForTest( {ClassUnderTesting.class} )
public class ClassUnderTestingTest {
@Test
public void shouldInitializeMocks() throws Exception {
CollaboratorToBeMocked mockedCollaborator = mock(CollaboratorToBeMocked.class);
suppress(constructor(CollaboratorToBeMocked.class, InjectedIntoCollaborator.class));
whenNew(CollaboratorToBeMocked.class)
.withArguments(InjectedAsTypeIntoCollaborator.class)
.thenReturn(mockedCollaborator);
new ClassUnderTesting().methodUnderTesting();
assertTrue(true);
}
}
这些是类:
public class ClassUnderTesting {
public void methodUnderTesting() {
new CollaboratorToBeMocked(InjectedAsTypeIntoCollaborator.class);
}
}
public class CollaboratorToBeMocked {
public CollaboratorToBeMocked(Class<InjectedAsTypeIntoCollaborator> clazz) {
}
public CollaboratorToBeMocked(InjectedIntoCollaborator someCollaborator) {
}
public CollaboratorToBeMocked() {
}
}
public class InjectedAsTypeIntoCollaborator {
}
public class InjectedIntoCollaborator {
}
这是错误:
org.powermock.reflect.exceptions.TooManyConstructorsFoundException: Several matching constructors found, please specify the argument parameter types so that PowerMock can determine which method you're refering to.
Matching constructors in class CollaboratorToBeMocked were:
CollaboratorToBeMocked( InjectedIntoCollaborator.class )
CollaboratorToBeMocked( java.lang.Class.class )
问题来了:如何让 PowerMock 找出要查找的构造函数？
有问题的行 是suppress。这就是错误的来源。
最佳答案
也许你的问题来不及了。今天遇到了，在下面的url找到了解决方案。基本上，您需要像这样指定参数类型。
whenNew(MimeMessage.class).**withParameterTypes(MyParameterType.class)**.withArguments(isA(MyParameter.class)).thenReturn(mimeMessageMock);

希望对您有所帮助。 :)
