 To test the templates, please perform the following:

-/bin/configs/python*` to update the Python-related samples under [`samples`](https://github.com/openapitools/openapi-generator/tree/master/samples). For Windows, please install [GIT bash](https://gitforwindows.org/). (If you find that there are new files g

If you've questions or concerns, please open a ticket to start a discussion)
 - During development it can be helpful to quickly regenerate the samples without recompiling all of openapi-generator, e.g. when you have only updated the mustache templates. This can be done by passing the `-t` parameter: `-t modules/openapi-generator/src/main/resources/python`.
 - Run the tests in the sample folder using maven `mvn integration-test -f /path/to/pom.xml`, e.g. `mvn integration-test -f samples/client/petstore/python/pom.xml`. (some languages may not contain unit testing for Petstore and we're looking for contribution from the community to implement those tests)
 - Finally, git commit the updated samples files: `git commit -a`
