如何在机器人框架中的测试套件中设置纪元时间和毫秒的全局变量？

Question

我实际上正在努力设置两个 API 请求以在我的机器人框架中启动数据库数据交换作业。 端点需要各种变量，例如纪元格式的 ${startTime}、${timePeriod}、以毫秒为单位的分钟或 $cronExpression} 以使请求可行。

但是，如果每次我都必须手动输入上面的参数并运行测试，但这些参数不在可读的实验室中，那么这是不可持续的...

为了在我的测试套件中使用该变量，我的想法是创建另一个机器人脚本来帮助和设置全局变量，以可读格式包含这些参数，而不是默认参数。但我对机器人框架结构很陌生，不太确定如何配置它......有人可以建议吗？

    set global variable  ${start_Time}

您应该在关键字下定义设置开始时间（或者可能是设置开始时间以明确），并将其设置为测试套件设置或测试用例设置。请注意，获取当前日期可以采用纪元格式
