@itling Thanks for the adapter update! 👍
Would you like to add a CI integration test for Burrow? The benchmark sample you submitted to the other repo would do it. Take a look at the other CI tests in the packages/caliper-test-integration directory.

I have already submitted the benchmark sample to the other repo. I don’t have time to write CI test case for the time being, it may not be submitted so quickly.
