拥有POJO
,例如:
public class ClientWebRequest {
private URI uri;
private HttpMethod httpMethod;
private final Header header;
private final Body body;
public ClientWebRequest(){
header = new Header();
body = new Body();
}
//getters and setters
关于JUnit
使用AssertJ
,以下内容有效,@Test
方法传递:
assertThat(clientWebRequest).isNotNull();
assertThat(clientWebRequest.getHeader()).isNotNull()
assertThat(clientWebRequest.getHeader().getAccept()).isNotNull();
assertThat(clientWebRequest.getHeader().getAcceptLanguage()).isNull();
assertThat(clientWebRequest.getHeader().getContentType()).isNull();
assertThat(clientWebRequest.getBody()).isNotNull();
assertThat(clientWebRequest.getBody().getBody()).isNull();
即使它起作用,也会以某种方式冗长。
我想知道是否可能只用一个句子重写所有上述内容,检查每个嵌套的属性/字段。因此,我尝试了以下例子:
assertThat(clientWebRequest.getHeader()).isNotNull()
.hasFieldOrProperty("accept").isNotNull()
.hasFieldOrProperty("acceptLanguage").isNull();
但失败并显示以下错误消息:
org.junit.ComparisonFailure: expected:<null>
but was:<Header [accept=[application/json;charset=UTF-8], acceptLanguage=null, contentType=null]>
at
我的主要目标是为isNotNull
isNull
和POJO
Alpha :感谢Joel
的建议,以下内容有效:
assertThat(clientWebRequest).isNotNull()
.extracting("header.accept")
.doesNotContainNull();
assertThat(clientWebRequest).isNotNull()
.extracting("header.acceptLanguage", "header.contentType")
.containsNull();
从上面(两个街区)如果我尝试以下(一个街区):
assertThat(clientWebRequest).isNotNull()
.extracting("header.accept")
.doesNotContainNull();
.extracting("header.acceptLanguage", "header.contentType")
.containsNull();
失败了。只是好奇是否可以应用一个块。
答案 0 :(得分:6)
我认为最好的方法是extract所有属性/字段,然后检查它不包含null。
示例:
TolkienCharacter frodo = new TolkienCharacter("Frodo", 33, HOBBIT);
// support nested properties:
assertThat(frodo).extracting("name", "age", "race.name")
.doesNotContainNull()
.containsExactly("Frodo", 33, "Hobbit");
请注意,您也可以使用测试对象中的lambdas to extract values。
assertThat(frodo).extracting(TolkienCharacter::getName,
character -> character.age,
character -> character.getRace().getName())
.containsExactly("Frodo", 33, "Hobbit");
