java - 无法理解的 JUnit 错误

Question

尝试通过预先将两个映射转换为列表来测试它们的相等性(包括顺序)。可能有更好的方法来做到这一点，但我想知道为什么会出现这个错误。这是测试:

@Test
public void sortedEntriesTest() {
    List<Map.Entry<String, AtomicInteger>> actualList = stream.sortedEntries(stream.getMap());
    List<Map.Entry<String, AtomicInteger>> expectedList = 
                                              expectedMap.entrySet()
                                                         .stream()
                                                         .sorted(Comparator.comparingInt(e -> -e.getValue().get()))
                                                         .collect(Collectors.toList());
    Assert.assertThat(expectedList, is(actualList));
}

这是错误:

java.lang.AssertionError: 
Expected: is <[file=1, for=1, project=1, is=1, an=1, just=1, example=1, this=2]>
 but: was <[file=1, for=1, project=1, is=1, an=1, just=1, example=1, this=2]>
Expected :is <[file=1, for=1, project=1, is=1, an=1, just=1, example=1, this=2]>

Actual   :<[file=1, for=1, project=1, is=1, an=1, just=1, example=1, this=2]>

Answer 1

尝试

Assert.assertThat(expectedList, is(equalTo(actualList)));

相反。
