如何解决 Jenkins 上的 python“测试”阶段错误？

Question

I am trying to build a CI/CD flow on Jenkins. I have my file updated on Jenkins but at a certain test stage, the code test fails meanwhile it does not fail in my local machine.

The test error on Jenkins is shown:

+ python cidr_convert_api/python/tests.py
..E..E

Ran 6 tests in 0.000s

FAILED (errors=2)

The passed test on my local machine is shown thus:

Image of passed test on machine

Then finally, a view of the build is shown thus: jenkins dashboard .

I have a dockerfile, the API file and other middleware and if you need any of them for more context, please request.

I'd really appreciate who could help in. Thanks!

Answer 1

Due to the dissimilarity between my local PC python and the Jenkins Python, I had to pass the python test command from docker and it ran comfortably.

I just added RUN python./tests.py and it worked like magic.

thanks!
