Junit - 如何测试List

背景

测试过程中,需要校验查询列表 返回数据的正确性。

常见的需求如:

  1. 验证查询条件正确性:输入某查询条件,验证返回结果的List所有记录的 该字段 均为输入条件;
  2. 验证数据正确性:验证查询结果中,某字段不能为空,某字段一定需要 > 0,某字段是个List,但是List的Size一定不为0;
  3. 添加数据后,查询列表可以包含该数据;

foreach 理论上也可以,但是每次写起来有点麻烦,就可以使用 hamcrest

方式

@Test
void object_list_test(){
    List<Person> list = Arrays.asList(
            new Person("bob", "andy"),
            new Person("bob", "judy")
    );


    //Test not empty list
    assertThat(list, not(IsEmptyCollection.empty()));

    //Test every object property
    assertThat(list, everyItem(hasProperty("firstName",not(blankOrNullString()))));
    assertThat(list, everyItem(hasProperty("firstName",is("bob"))));

    //Test contains object property
    assertThat(list, hasItem(hasProperty("lastName",is("andy"))));

    //Test contains object
    Person person = new Person("bob","andy");
    assertThat(list, hasItem(person));

    assertThat(list, IsCollectionWithSize.hasSize(2));
}
