* closePercentInterestRefresh.test.js — 部分平仓比例变更触发利息腿刷新守卫
|
||
* ============================================================================
|
||
* 目的：验证用户从「全部平仓」切换到「部分平仓」并修改比例时，
|
||
* getInterestList() 被调用且传递的 closePercent 值是正确的（口径A）。
|
||
*
|
||
* 测试策略：
|
||
* 1. 源码守卫（wiring guard）：读 unwindSwapTrade.js 源码文本，断言关键方法
|
||
* 在比例变更后确实调用 getInterestList()。
|
||
* 2. 行为模拟（behavior mock）：在 vm sandbox 中加载 unwindSwapTrade.js，
|
||
* mock main.post 捕获 postData，验证不同 closePercent 值被正确传递。
|
||
* ============================================================================
