Test one (during the first 15 mins):
-
Test one is to send simple requests with gradually increased virtual users. Choose the methods below. You can decide the request combination and the request order. Then follow the 3×5 mins VU rules to send requests to the BlockPI network. Save the resulting output of the load testing tool at the end. Check out the k6 docs to specify different VUs at different time https://k6.io/docs/test-types/soak-testing.
-
Methods: klay_getTransactionBy*******, klay_blockNumber, klay_getTransactionReceipt
3×5 mins VU rules:
- First 5 minutes: 500 virtual users.
- Second 5 minutes: 1000 virtual users.
- Third 5 minutes: 2000 virtual users.
Test two (during the second 15 mins):
-
Test two is to send requests to interact with a dapp contract. Find out the target contract abi and write a script to get the token price with "estimatePos" method. Then follow the 3×5 mins VU rules to send requests to the BlockPI network. Save the resulting output of the load testing tool at the end.

NOTE: If you faced an issue with max file open
Increase file limit
sudo bash -c "cat >/etc/security/limits.d/90-blockpi-nofiles.conf <<EOF
# Increase process file descriptor count limit

Close all open sessions (log out then, in again)
