我试图弄清楚如何org.mockito.AdditionalMatchers工作,但我失败了。为什么这个测试失败了?

import static org.hamcrest.CoreMatchers.is;
import static org.junit.Assert.*;
import static org.mockito.AdditionalMatchers.*;

public class DemoTest {

    @Test
    public void testGreaterThan() throws Exception {

        assertThat( 17
            , is( gt( 10 ) )
        );
    }
}

输出是:

java.lang.AssertionError: 
Expected: is <0>
     got: <17>

在这种情况下,您应该使用 Hamcrest 的greaterThangt用于验证模拟对象中方法调用的参数:

public class DemoTest {

    private List<Integer> list = Mockito.mock(List.class);

    @Test
    public void testGreaterThan() throws Exception {
        assertThat(17, is(org.hamcrest.Matchers.greaterThan(10)));

        list.add(17);
        verify(list).add(org.mockito.AdditionalMatchers.gt(10));
    }

}
