-- Update the Petstore sample by running the shell scripts under the `bin` folder. For example, run `./bin/generate-samples.sh ./bin/configs/python*` to update the Python-related samples under [`samples`](https://github.com/openapi-json-schema-tools/openapi-json-schema-generator/tree/master/samples). For Windows, please install [GIT bash](https://gitforwindows.org/).

 - 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). __Please notice:__ you must run a local instance of the Petstore server in order to perform the tests, as running them against petstore.swagger.io is not supported anymore. Please refer to item 3 of [Integration Tests - How to add integration tests for new Petstore samples](https://github.com/OpenAPITools/openapi-generator/wiki/Integration-Tests#how-to-add-integration-tests-for-new-petstore-samples) to learn how to quickly configure and run it.
 - Finally, git commit the updated samples files: `git commit -a` (`git add -A` if added files with new test cases)
