Question

如何测试第一个静态方法method(String str, Param param)？

public class Example {

    public static Example method(String str, Param param) {
        return method(str, param, null);
    }

    private static Example method(String str, Param param, SomeClass obj) {
        // ...
    }
}

我尝试使用下面的代码进行测试

@Test
public void should_invoke_overloaded_method() throws Exception {

    final String str  = "someString";    
    mockStatic(Example.class);

    when(Example.method(str, paramMock))
            .thenCallRealMethod();

    when(Example.method(str, paramMock, null))
            .thenReturn(expectedMock);

    Example.method(str, paramMock);
    verifyStatic();
}

但没有运气。我如何修复例如此测试来验证第二种方法的调用？

此代码有效：

import static org.junit.Assert.assertSame;
import static org.powermock.api.mockito.PowerMockito.mock;
import static org.powermock.api.mockito.PowerMockito.mockStatic;
import static org.powermock.api.mockito.PowerMockito.when;

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(Example.class)
public class ExampleTest {
    @Test
    public void should_invoke_overloaded_method() throws Exception {
        final String str = "someString";
        Param paramMock = mock(Param.class);
        Example expectedMock = mock(Example.class);

        mockStatic(Example.class);

        when(Example.method(str, paramMock)).thenCallRealMethod();
        when(Example.class, "method", str, paramMock, null).thenReturn(expectedMock);

        assertSame(expectedMock, Example.method(str, paramMock));
    }
}

如何使用PowerMockito测试两个静态方法（一个调用另一个）？
