模拟静态方法不起作用

Question

我编写的代码只是使用 powermock 模拟了一个静态方法。

在运行测试用例时，没有最后一次调用可用的模拟。

调试时发现在expect语句中抛出。

异常 throwm 的堆栈跟踪：

java.lang.IllegalStateException: no last call on a mock available
at org.easymock.EasyMock.getControlForLastCall(EasyMock.java:466)
at org.easymock.EasyMock.expect(EasyMock.java:444)
at junit.util.mock.Test.test1(Test.java:26)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
....
....

编写的测试类：

import static org.junit.Assert.assertEquals;

import static org.powermock.api.easymock.PowerMock.mockStatic;
import static  org.powermock.api.support.membermodification.MemberMatcher.constructor;

import org.easymock.EasyMock;
import static org.powermock.api.support.membermodification.MemberModifier.suppress;
import static org.easymock.EasyMock.expect;
import org.junit.runner.RunWith;
import org.powermock.api.easymock.PowerMock;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
import static org.powermock.api.easymock.PowerMock.replayAll;

import Testing;

@RunWith(PowerMockRunner.class)
@PrepareForTest({Testing.class})
public class Test {

 @org.junit.Test
 public void test1() {
mockStatic(Testing.class);
expect(Testing.getWord()).andReturn("my Cal").anyTimes();
PowerMock.replay(Testing.class);
PowerMock.verify(Testing.class);
assertEquals(Testing.getWord(),"my Cal");
}
}

待测类：

public class Testing {
public static String getWord() {
    return "from test";
    }
}

我试过你的代码，它工作得很好。所以我不知道该说什么。不正确的一件事是verify 应该在最后。但这不是导致问题的原因。

我可以给你我使用的依赖项，以防它与此相关。
