1. 外部库random的使用

#错误
${ran int}=    Evaluate random.randint(0, sys.maxsize)


# 正确
I'm surprised the randint() doesn't work for you - did you use the correct syntax, Evaluate must point/end with the external module you're using, "random" in this case?
${ran int}=    Evaluate    random.randint(0, sys.maxsize)    random
