协议提供程序验证失败,并显示: 对于输入字符串:"null"



我试图在提供商端进行验证,但出现错误-

验证DataConsumer和DataProvider之间的协定[使用File pact/DataConsumer DataProvider.json]给定某种状态请求json数据请求失败-对于输入字符串:";\空";

不确定我错过了什么。

我的Pojo-

@EqualsAndHashCode
@RequiredArgsConstructor
@Builder(toBuilder = true)
@JsonDeserialize(builder = DataModel.DataModelBuilder.class)
public class DataModel {
@JsonProperty("name")
private final String name;
@JsonProperty("price")
private final double price;
}

合同-

测试-


@ExtendWith(SpringExtension.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@Provider("DataProvider")
@PactFolder(value = "pact")
public class ContractVerificationTest {
@TestTemplate
@ExtendWith(PactVerificationSpringProvider.class)
void pactVerificationTestTemplate(PactVerificationContext context) {
context.verifyInteraction();
}
@State("some state")
void testPact() {
}
}

在提供者测试中,您没有返回提供者状态注释中的值(名称、价格((它目前什么都不做(,因此当Pact试图动态替换请求中的值时,它们为null。

你真的需要它们首先由提供者生成吗?

请参阅https://pactflow.io/blog/injecting-values-from-provider-states/有关如何使用和修复的详细示例。

更新可能是您对参数进行了双重转义吗?

示例中:

.queryParameterFromProviderState("accountNumber", "${accountNumber}", "100")

在您的代码中:

.valueFromProviderState("price", "\${price}", 10.0)
