我目前在JUnit测试中遇到困难,需要一些帮助。所以我用静态方法得到了这个类,它将重构一些对象。为简化起见,我举了一个小例子。这是我的工厂类:
class Factory {
public static String factorObject() throws Exception {
String s = "Hello Mary Lou";
checkString(s);
return s;
}
private static void checkString(String s) throws Exception {
throw new Exception();
}
}
这是我的测试课程:
@RunWith(PowerMockRunner.class)
@PrepareForTest({ Factory.class })
public class Tests extends TestCase {
public void testFactory() throws Exception {
mockStatic(Factory.class);
suppress(method(Factory.class, "checkString"));
String s = Factory.factorObject();
assertEquals("Hello Mary Lou", s);
}
}
基本上我试图实现的是私有方法checkString()应该被抑制(因此不抛出Exception),还需要验证方法checkString()实际上是在方法factorObject()中调用的。
已更新: 使用以下代码可以正常进行抑制:
suppress(method(Factory.class, "checkString", String.class));
String s = Factory.factorObject();
...然而它为String“s”返回NULL。那是为什么?

好的,我终于找到了所有问题的解决方案。如果有人遇到类似问题,请输入以下代码:
import junit.framework.TestCase;
import org.junit.runner.RunWith;
import org.mockito.Mockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
import static org.mockito.Mockito.anyString;
import static org.mockito.Mockito.times;
import static org.powermock.api.support.membermodification.MemberModifier.suppress;
import static org.powermock.api.support.membermodification.MemberMatcher.method;
import static org.powermock.api.mockito.PowerMockito.mockStatic;
import static org.powermock.api.mockito.PowerMockito.verifyPrivate;
@RunWith(PowerMockRunner.class)
@PrepareForTest(Factory.class)
public class Tests extends TestCase {
public void testFactory() throws Exception {
mockStatic(Factory.class, Mockito.CALLS_REAL_METHODS);
suppress(method(Factory.class, "checkString", String.class));
String s = Factory.factorObject();
verifyPrivate(Factory.class, times(1)).invoke("checkString", anyString());
assertEquals("Hello Mary Lou", s);
}
}

哟可以这样做:
PowerMockito.doNothing().when(Factory.class,"checkString");
有关详细信息,请访问:

编辑:
ClassToTest spy = spy(new ClassToTest ());
doNothing().when(spy).methodToSkip();
spy.methodToTest();
