Description

After generating a python client for peertube, the tests don't run due to syntax errors:

• CI job
• file with syntax error

openapi-generator version

@openapitools/openapi-generator-cli^1.0.10-4.2.3

OpenAPI declaration file content or url

https://framagit.org/LoveIsGrief/PeerTube/blob/44d4ee4fcb7cf8beebac73f85693c09919b91e66/support/doc/api/openapi.yaml

Command line used for generation

It's run in a bash script by a CI that calls the npm package. bash script | npm package (@openapitools/openapi-generator-cli^1.0.10-4.2.3) (line in yarn.lock)

the resulting command should be

npx openapi-generator generate
-i support/doc/api/openapi.yaml
-c "support/openapi/python/def.yaml"
-t "support/openapi/python"
-g "python"
--git-host "framagit"
--git-user-id "peertube-test"
--git-repo-id "apis/python"
-o "dist/api/python"

Steps to reproduce

1. Generate python client from peertube api spec
2. install virtualenv in output directory
3. install requirements.txt and test-requirements.txt
4. pytest

Related issues/PRs

https://github.com/OpenAPITools/openapi-generator/issues/1747 had similar issues but the output was ignored? I'm not entirely sure.

Suggest a fix

Update the template to use the correct fieldnames. They are correctly generated in the model, but not in the test file.

Start by generating the Python client from the linked PeerTube OpenAPI declaration using the shown command and the support/openapi/python/def.yaml configuration, then run pytest in the generated output. Compare the syntax error in test/test_server_config_custom_transcoding.py with the corresponding generated model fields. Done means the generated tests parse and run without syntax errors.
