How to test Flink SQL UDF with open method?

[zhouhaifengmath]

Hi,

I am trying to test a flink sql udf which has open method to get some parameters with Flink1.14, but i can't find an example to set those parameters in a test. Can someone give me a example on this question? Thanks for your help~

Thanks && Regards
