如何复制通话结果

问题描述

为什么以下测试未通过?我一定缺少一些有关复制工作原理的基本知识.它似乎是对json对象的引用，而不是副本.

Why does the following test not pass? I must be missing something fundamental about how copy works. It seems to have a reference to the json object and not a copy.

Feature: testing

  @one
  Scenario: one
    * def root = { name: 'inner' }

  Scenario: two
    * def a = call read('testing.feature@one')
    * copy b = a
    * set b.root.name = "copy"
    * match b.root.name == "copy"
    * match a.root.name == "called"

推荐答案

始终解开call的结果.原因是特定的JSON对象是特殊的"(Java映射)，它不遵循copy的规则-因为您可以引用其他Java对象.这样就可以了:

Always un-wrap the results of call. The reason is that particular JSON object is "special" (a Java map) which does not follow the rules of copy - because you can have references to other Java objects. So this will work:

  @one
  Scenario: one
    * def root = { name: 'inner' }

  Scenario: two
    * def temp = call read('dev.feature@one')
    * def a = temp.root
    * copy b = a
    * set b.name = "copy"
    * match b.name == "copy"
    * match a.name == "inner"
