Testing

How to test, if my oracle can communicate with plugin and start sharing the data

In your, remix IDE open a new file and name it as PluginClient.sol and copy and paste the code contents.

Override your oracle address & job id in below client contract and deploy it in a remix by overriding the PLI mainnet address like below (Line numbers 21 & 22) in the smart contract to be replaced with your oracle contract address & job-id from the previous steps

}

After deployment, you will receive a contract address- In this case here it is -> xdc3017a414bf657a42fc183143e90d378f05ff0004

Fund your contract address with PLI ( let’s say 1 PLI) before you trigger the sleep task like below

Once you submit the “requestAlarm”, a job will be triggered in your PLUGIN Node like below.

After a couple of seconds, you should see the job is getting completed successfully
