在hamcrest中包含对面

Question

包含的相反之处是什么？

    List<String> list = Arrays.asList("b", "a", "c");
    // should fail, because "d" is not in the list

    expectedInList = new String[]{"a","b", "c", "d"};
    Assert.assertThat(list, Matchers.contains(expectedInList));


    // should fail, because a IS in the list
    shouldNotBeInList = Arrays.asList("a","e", "f", "d");
    Assert.assertThat(list, _does_not_contains_any_of_(shouldNotBeInList)));

应该是_does_not_contains_any_of_什么？

Answer 1

您可以通过以下方式组合三个内置匹配器:

import static org.hamcrest.Matchers.everyItem;
import static org.hamcrest.Matchers.isIn;
import static org.hamcrest.Matchers.not;

@Test
public void hamcrestTest() throws Exception {
    List<String> list = Arrays.asList("b", "a", "c");
    List<String> shouldNotBeInList = Arrays.asList("a", "e", "f", "d");
    Assert.assertThat(list, everyItem(not(isIn(shouldNotBeInList))));
}

执行此测试将为您提供:

预期:每个项目都不是{"a","e","f","d"}之一
但是:项目是"a"
