Java 柑橘框架-可以从响应中分配变量吗？

我正在尝试测试以下两个REST调用：

请求1

GET getLatestVersion
Response: {"version": 10}

请求2

POST getVersionData (body={"version": 10})
Response: {"version": 10, data: [...]}

是否可以将请求1中的“版本”分配给同一测试中请求2中使用的变量

@CitrusTest(name = "SimpleIT.getVersionTest")
public void getVersionTest() { 
    // Request 1
    http()
            .client("restClient")
            .send()
            .get("/getLatestVersion")
            .accept("application/json");

    http()
            .client("restClient")
            .receive()
            .response(HttpStatus.OK)
            .messageType(MessageType.JSON)
            // Can the version be assigned to a variable here?
            .payload("{\"version\":10}");

    // Request 2
    http()
            .client("restClient")
            .send()
            .post("/getVersionData")
            // Idealy this would be a Citrus variable from the previous response
            .payload("{\"version\":10}")
            .accept("application/json");

    http()
            .client("restClient")
            .receive()
            .response(HttpStatus.OK)
            .messageType(MessageType.JSON)
            .payload("\"version\": 10, data: [...]");
}

一种有效的方法是从TestContext中提取值并将其指定为变量

@CitrusTest(name = "SimpleIT.getVersionTest")
@Test
public void getVersionTest(@CitrusResource TestContext context) {

    http(httpActionBuilder -> httpActionBuilder
        .client("restClient")
        .send()
        .get("/getLatestVersion")
        .name("request1")
        .accept("application/json")
    );

    http(httpActionBuilder -> httpActionBuilder
        .client("restClient")
        .receive()
        .response(HttpStatus.OK)
        .messageType(MessageType.JSON)
        .payload("{\"version\":\"@greaterThan(0)@\"}")
    );

    // This extracts the version and assigns it as a variable
    groovy(action -> action.script(new ClassPathResource("addVariable.groovy")));

    http(httpActionBuilder -> httpActionBuilder
            .client("restClient")
            .send()
            .post("/getVersionData")
            .payload("{\"version\":${versionId}}")
            .accept("application/json")
    );

    http(httpActionBuilder -> httpActionBuilder
            .client("restClient")
            .receive()
            .response(HttpStatus.OK)
            .messageType(MessageType.JSON)
    );
}

addVariable.groovy

这将从响应中提取变量并将其添加到TestContext

import com.consol.citrus.message.Message
import groovy.json.JsonSlurper

Message message = context.getMessageStore().getMessage("receive(restClient)");

def jsonSlurper = new JsonSlurper();
def payload = jsonSlurper.parseText((String) message.getPayload())

// Set the version as a variable in the TestContext
context.getVariables().put("versionId", payload.version)

问题

• 有没有更整洁的方法
• 在MessageStore中是否有命名消息的方法

您可以使用JsonPath表达式：

http()
    .client("restClient")
    .receive()
    .response(HttpStatus.OK)
    .messageType(MessageType.JSON)
    .extractFromPayload("$.version", "apiVersion")
    .payload("{\"version\":\"@ignore@\"}");

或者，您可以在有效负载中使用创建变量匹配器：

http()
    .client("restClient")
    .receive()
    .response(HttpStatus.OK)
    .messageType(MessageType.JSON)
    .payload("{\"version\":\"@variable('apiVersion')@\"}");

---

这两个选项都将创建一个新的测试变量

apiVersion

，您可以在进一步的测试操作中使用

${apiVersion}

引用该变量。
