Question

我正在尝试使用Mockito来模拟服务，但是它说我没有正确使用参数Mather。

import com.spmsoftware.appframework.validation.ValidationContext;
import com.spmsoftware.appframework.validation.ValidationContextSupport;
import com.spmsoftware.filters.api.model.Filter;
import com.spmsoftware.filters.api.validation.FilterValidationService;
import com.spmsoftware.tablereference.api.service.TableReferenceService;
import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;
import org.mockito.runners.MockitoJUnitRunner;

import static org.mockito.Matchers.anyLong;
import static org.mockito.Matchers.anyObject;
import static org.mockito.Mockito.when;

public class TestInputTabValidator {
    @Mock
    private Filter filter;
    @Mock
    private TableReferenceService tableReferenceService;
    @Mock
    private FilterValidationService filterValidationService;


    @InjectMocks private InputTabValidator inputTabValidator;


    @Before
    public void setUp() {
        MockitoAnnotations.initMocks(this);
        preCondition();
    }

    private void preCondition() {
        when(tableReferenceService.getTable(anyLong())).thenReturn(anyObject());
        when(tableReferenceService.tableExists(1L)).thenReturn(true);
    }

    @Test
    public void validateInputTabSaveWithFilter() {
        ValidationContext validationContext = new ValidationContextSupport();
        inputTabValidator.validate(new Object[]{anyLong(), filter}, validationContext);
        Assert.assertTrue("no validation errors recorded", !validationContext.hasErrors());

    }

    public void validateInputTabSaveWithoutFilter() {
        ValidationContext validationContext = new ValidationContextSupport();
        inputTabValidator.validate(new Object[]{anyLong()}, validationContext);

        Assert.assertTrue("no validation errors recorded", !validationContext.hasErrors());

    }

} 




 org.mockito.exceptions.misusing.InvalidUseOfMatchersException: 
 Invalid use of argument matchers!
 1 matchers expected, 2 recorded:
 -> at com.spmsoftware.genericWebservices.validator.TestInputTabValidator.preCondition(TestInputTabValidator.java:55)
 -> at com.spmsoftware.genericWebservices.validator.TestInputTabValidator.preCondition(TestInputTabValidator.java:56)

 This exception may occur if matchers are combined with raw values:
     //incorrect:
     someMethod(anyObject(), "raw String");
 When using matchers, all arguments have to be provided by matchers.
 For example:
     //correct:
     someMethod(anyObject(), eq("String by matcher"));

 For more info see javadoc for Matchers class.

原因归因于Mockito.any(MessageCreator.class)，但是没有办法测试我的发送方法是否在MessageCreator中没有创建实际对象的情况下执行？

问题出在以下几行：

when(tableReferenceService.getTable(anyLong())).thenReturn(anyObject());

您无法使用匹配器作为预期的返回值。你想要的可能是：

when(tableReferenceService.getTable(anyLong())).thenReturn(new Table());

或

Table table = mock(Table.class);
when(tableReferenceService.getTable(anyLong())).thenReturn(table);

取决于tableReferenceService.getTable()返回的对象是否需要嘲笑。

获取org.mockito.exceptions.misusing.InvalidUseOfMatchersException异常，即使我已正确使用了Mather
