在测试中,我使用的是模拟对象:
@Mock
ListMultipleChoice<String> listMultipleChoiceMock;
我尝试验证其方法的使用:
verify(listMultipleChoiceMock).setRequired(true);
verify(listMultipleChoiceMock).setMaxRows(2);
verify(listMultipleChoiceMock).setDefaultModel(any(IModel.class));
但它引发了以下异常:
org.mockito.exceptions.misusing.UnfinishedVerificationException: 缺少方法调用验证(模拟):
此行的例外情况:
verify(listMultipleChoiceMock).setMaxRows(2);
setMaxRows接受一个int。
当我评论此行时,测试成功。当我调试我的程序时,我可以看到设置setMaxRows的方法:
brandsListMultipleChoice.setMaxRows(brandLabels.size());
brandLabels是List,size()返回一个int。
我检查了brandLabels的大小,它是2.我已经尝试过anyInt()和0,两者都会导致抛出异常。
我做错了什么?为什么这个验证没有成功?
以下是我的代码示例,该代码将失败:
import org.apache.wicket.markup.html.form.ListMultipleChoice;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.Mock;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
import static org.mockito.Matchers.anyObject;
import static org.mockito.Mockito.verify;
import static org.powermock.api.mockito.PowerMockito.whenNew;
@RunWith(PowerMockRunner.class)
@PrepareForTest({Example.class})
public class ExampleTest {
@Mock
ListMultipleChoice<String> brandsListMultipleChoiceMock;
@Before
public void setUp() throws Exception {
whenNew(ListMultipleChoice.class).withAnyArguments().thenReturn(brandsListMultipleChoiceMock);
Example example = new Example();
}
@Test
public void test() throws Exception {
verify(brandsListMultipleChoiceMock).setRequired(true);
verify(brandsListMultipleChoiceMock).setMaxRows(1);
verify(brandsListMultipleChoiceMock).setDefaultModel(anyObject());
}
}
正在测试的课程:
import org.apache.wicket.markup.html.form.ListMultipleChoice;
import org.apache.wicket.model.IModel;
import org.apache.wicket.model.PropertyModel;
import java.util.ArrayList;
import java.util.HashSet;
import java.util.List;
import java.util.Set;
public class Example {
private ListMultipleChoice<String> brandsListMultipleChoice;
public Example() {
List<String> brandLabels = new ArrayList<>();
brandLabels.add("DEMO");
brandsListMultipleChoice = new ListMultipleChoice<>("brands", new PropertyModel<Set<String>>(this, "brandProperty"), brandLabels);
brandsListMultipleChoice.setRequired(true);
brandsListMultipleChoice.setMaxRows(brandLabels.size());
brandsListMultipleChoice.setDefaultModel(new IModel<Set<String>>() {
private Set<String> list = new HashSet<>();
@Override
public Set<String> getObject() {
return list;
}
@Override
public void setObject(Set<String> ts) {
list = ts;
}
@Override
public void detach() {
}
});
}
}
当我注释掉第二个或第三个验证规则时,测试成功。

我尝试编写简单的测试:
public class ListMultipleChoiceTest {
public class ListMultipleChoice<T>{
public void setMaxRows(int maxRows) {
}
}
@Mock
ListMultipleChoice<String> listMultipleChoiceMock;
@Test
public void testSetMaxRows() {
verify(listMultipleChoiceMock, never()).setMaxRows(2);
listMultipleChoiceMock.setMaxRows(2);
verify(listMultipleChoiceMock).setMaxRows(2);
}
}
它成功通过。 您应该仔细检查您的课程用法。 或者提供更多代码示例。

显然无法模拟最终方法。
解决这个问题的方法是将模拟类添加到注释@PrepareForTest(ListMultipleChoice.class)
通过这种方式,PowerMockito将处理模拟对象。
