Gatling:获取REST资源,更改JSON叶子,回发

标签: json scala rest jsonpath gatling

我正在研究测试脚本,使用Scala在Gatling中测试REST接口。

对于特定的REST资源,这是我想要实现的目标:

  1. 获取资源(这将为我提供正文中的JSON数据)。
  2. 使用jsonpath更改正文中的值。
  3. 将修改后的正文发布回相同的网址
  4. 我已经成功使用1和3.唯一的问题是更改似乎是字符串格式的json数据。

    测试步骤

    object WebTestCollection {
    
    
        def getAccountDetails() = http("Get account")
          .get("/account")
          .check(jsonPath("$.billingAccount").saveAs("accountjson"))
    
    
        def postNewAccountDetails() = http("Post modified account")
          .post("/account").asJSON
          .body("${accountjson}")
    
    }
    

    部分情景

    val scn = scenario("Web Usage")
        .feed(testRuns)
    
    
            .exec(WebTestCollection.getAccountDetails())
            .exitHereIfFailed
    
            .exec(session => {
                  var account = session.getAttribute("accountjson")
                  account.notes = "Performance Test Comment"
                  println(account)
                  session.setAttribute("accountjson", account)
              }
            )       
    
            .exec(WebTestCollection.postNewAccountDetails())
            .exitHereIfFailed
    

    我收到以下错误

只有当前的Gatling 2快照可以save JsonPath result into something else than String

jsonPath(expression).ofType[T]

但是,我们目前没有编辑工具,然后重新序列化JSON AST。 我们提供JSON解析器(Boon和Jackson),因此您可以自己实现。您也可以打开功能请求。
