How to debug a simtest sample?

[oday0311]

there are many test function in sui with simtest init, how can we debug the test functions to know more about the process?

[sim_test]

async fn sim_execute_transaction_transfer()

@oday0311 Please do not install anything from random strangers on the internet.

Can you please clarify your question, what process are you referring to and what kind of debugging do you have in mind?

thanks for your remind, I check last person 's account , did not install his shit.

well, I just have some work with detail process of some simtest cases, I am using goland Ide with rust support, it is normal to debug with cargo normal test cases, but as for simtest test cases, I can not use the ide or any other way to set a break point to check the local vari or values.

so I normal using info!() logs to debug simtest cases. but it cost a lot of time to repeat,

is there any way , we can debug like normal case for simtest. set a breakpoint and check some of the values.

thanks again.

Got it. Honestly, I haven't used simtests. So for running simtests, you'd need to install https://github.com/MystenLabs/sui/blob/main/scripts/simtest/install.sh this script, and then I think you can do cargo simtest.

Debugging with breakpoints I do not know. I will relay this question internally!

thanks for your help. for running simtest, there are enough hint for the project to install simtest , but sometimes we need to debug simtest, please refer..

One option could be to switch to a [tokio::test] for that particular test, and debug it like this.

Or you can add logs to relevant code paths and use RUST_LOG environment variable to adjust the log level.
