java - 是否可以使用FieldByFieldElementComparator 从assertJ 中排除某些字段？

Question

如何实现以下目标:

List<Data> streams = new ArrayList<>();
assertThat(streams).usingFieldByFieldElementComparatorIgnoringGivenFields("createdOn").containsOnly(data1, data2);

Answer 1

使用ListAssert.usingElementComparatorIgnoringFields(String... fields)与 ListAssert.usingFieldByFieldElementComparator() 做同样的事情但是允许忽略一些字段/属性:

Use field/property by field/property comparison on all fields/properties except the given ones

所以你可以这样写:

List<Data> streams = new ArrayList<>();
//...
Assertions.assertThat(streams)
          .usingElementComparatorIgnoringFields("createdOn")
          .containsOnly(data1, data2);
