gitlab-ci.yml: 'script: -pytest cannot find any tests to check'

问题

I'm having trouble implementing a toy example that runs pytest within .gitlab-ci.yml

gitlab_ci is a repo containing a single file test_hello.py

gitlab_ci/
    test_hello.py

test_hello.py

# test_hello.py

import pytest

def hello():
    print("hello")

def hello_test():
    assert hello() == 'hello'

.gitlab-ci.yml

# .gitlab-ci.yml

pytest:
  image: python:3.6
  script:
    - apt-get update -q -y
    - pip install pytest
    - pytest # if this is removed, the job outputs 'Success'

CI/CD terminal output

$ pytest
=== test session starts ===
platform linux -- Python 3.6.9, pytest-5.2.0, py-1.8.0, pluggy-0.13.0
rootdir: /builds/kunov/gitlab_ci
collected 0 items

=== no tests ran in 0.02s ===
ERROR: Job failed: exit code 1

I'm not sure why the test did not run... pytest does not seem to recognize test_hello.py

Solution

Put the python file inside the newly creared tests folder:

gitlab_ci/
    .gitlab-ci.yml
    tests/
        test_hello.py

Modify gitlab-ci.yml in the following manner:

# .gitlab-ci.yml

pytest:
  image: python:3.6
  script:
  - apt-get update -q -y
  - pip install pytest
  - pwd
  - ls -l
  - export PYTHONPATH="$PYTHONPATH:."
  - python -c "import sys;print(sys.path)"
  - pytest

And test_hello.py would stay the same as before.

This blog post mentions a similar pipeline, but:

However, this did not work as pytest was unable to find the ‘bild’ module (ie. the source code) to test.
The problem encountered here is that the ‘bild’ module is not able to be found by the test_*.py files, as the top-level directory of the project was not being specified in the system path:

pytest:
  stage: Test
  script:
  - pwd
  - ls -l
  - export PYTHONPATH="$PYTHONPATH:."
  - python -c "import sys;print(sys.path)"
  - pytest

The OP kunov confirms in the comments:

It works now! I put the single file inside a newly created folder called 'test'
