升级 Spring Boot 版本后的单元测试 hasOnlyOneElementSatisfying() 方法不起作用

Question

单元测试在其以前的版本中运行良好，而在更新版本后它显示错误

public class PersonSearchUtil {
    private final HashSet<SearchResponse> result = new HashSet<>();
    .
    .
    .
    public HashSet<SearchResponse> getResult() {
            return result;
    }
}

测试方法

@Test
fun `When person id is all zeroes, should merge`() {
    val uuid = UUID.randomUUID()
    add() {
        eeId = "same eeId"
        personId = UUID(0,0)
    }
    add() {
        eeId = "same eeId"
        personId = uuid
    }

    assertThat(service.result)
            .hasSize(1)
            .hasOnlyOneElementSatisfying { response ->.  // hasOnlyOneElementSatisfying is deprecated 
                assertThat(response.eeId).isEqualTo("same eeId")  // shows Unresolved reference: eeId 
                assertThat(response.personId).isEqualTo(uuid)  // shows Unresolved reference: personId
            }
}

错误：

未解决的参考：eeId

未解决的参考：personId

如javadoc中所述，应使用singleElement()代替。

此外，Kotlin 和最新版本的 AssertJ ( assertj/assertj-core#2439 ) 存在一个已知问题。

以下解决方法之一可能会解决您的问题，直到在 AssertJ 中得到解决：

assertThat(service.result as Iterable<SearchResponse>)
    .hasSize(1)
    .hasOnlyOneElementSatisfying { response ->
        assertThat(response.eeId).isEqualTo("same eeId")
        assertThat(response.personId).isEqualTo(uuid)
    }
}

CollectionAssert(service.result)
    .hasSize(1)
    .hasOnlyOneElementSatisfying { response ->
        assertThat(response.eeId).isEqualTo("same eeId")
        assertThat(response.personId).isEqualTo(uuid)
    }
}
