Failing tests in cloned repository

[piepor]

Environment:

• eKuiper version: v2.4.0-beta.3
• Hardware configuration:
  Architecture: x86_64
  CPU op-mode(s): 32-bit, 64-bit
  Address sizes: 39 bits physical, 48 bits virtual
  Byte Order: Little Endian
• OS:
  NAME="TUXEDO OS"
  VERSION="24.04.3 LTS"
  ID=tuxedo
  ID_LIKE="ubuntu debian"

What happened and what you expected to happen: Running the test suite on a clean upstream checkout results in several test failures. All existing tests were expected to pass on the upstream codebase, failing only as a result of local changes.

How to reproduce it (as minimally and precisely as possible): go test ./... or go test ./... -race in the project root

Anything else we need to know?: It's the first time I am contributing to the project. I've read the contributing guide and I think I've done everything suggested but it is possible that I missed something.

Hi,

I might be misunderstanding the issue, but I experienced something similar on my side. If I remember correctly, I was able to resolve it on my Fedora machine by running the following command:

mkdir -p data log plugins/sinks plugins/sources plugins/functions uploads

After creating these directories, the problem was fixed for me.

Hope this helps!

Hi,

I've looked better into the failed tests. Creating those directories solves some of them while others were related to missing packages zeromq and onnxruntime; however a lot more seems to be simply failing unit tests. In the following part I report four examples of them:

To launch the tests, I simply run the following command in the project root directory:

go test ./...

Am I missing something? Do you think is a problem of my environment somehow? Do you think is worth investigating more and submitting a PR?

I am sorry for the long post but I'm trying to set up my system in order to contribute to this great project.

Thank you very much for your help!
