Run Keyword If语法无效

Question

为什么以下Robot语句抱怨"Convert To Integer"关键字是无效语法？感谢

---

Run Keyword If    Convert To Integer    ${packets_2}    <=    Convert To Integer    ${packets_1}
...    FAIL    ${n}[FAILED] Packets 2 not greater than packets 1.
...    ${n}packets_time1: ${packets_1}  ${n}packets_time2: ${packets_2}

Answer 1

不能调用关键字作为Run Keyword If的条件。第一个参数应该是python表达式。由于您试图对一个整数进行比较，因此可以直接在表达式中这样做：

Run keyword if  int('${packets_2}') <= int('${packets_1})
...  FAIL  n[FAILED] Packets 2 not greater than packets 1

另一个问题是您提供了另外两个参数：${n}packets_time1: ${packets_1}和${n}packets_time2: ${packets_2}。目前还不清楚你认为这些是为了什么。我猜您希望将它们作为错误消息的一部分。如果是这样的话，它必须全部在一行上，否则机器人会认为它们是FAIL关键字的额外参数。

Run keyword if  int('${packets_2}') <= int('${packets_1})
...  FAIL  n[FAILED] Packets 2 not greater than packets 1n$packets_time1: ${packets_1}npackets_time2: ${packets_2}
