[BUG] Generation of test cases are failing for spring.

[jskhedkarl]

OpenAPI generator is not generating Integration test cases for spring API's Using the following generator to generate spring based code from openAPI specification. 4.0.2</openapi-generator-maven-plugin.version> swagger spec https://github.com/OAI/OpenAPI-Specification/blob/master/examples/v3.0/petstore.yaml

However, older swagger-codegen is able to generate integration test cases for API's.

Major difference between openapi-generator and swagger-codegen-cli is that template file api_test.mustache is missing in former.

https://github.com/swagger-api/swagger-codegen/tree/master/modules/swagger-codegen/src/main/resources/JavaSpring/libraries/spring-mvc

I don't know if it is a bug or test case generation is not supported for spring in openapi-generator.

Same issue I m facing, Please resolve this on priority

I don't know why they have been removed, but I think more useful test must be generated because previous only assert that we have NOT_IMPLEMENTED default implementation generated and nothing linked to the real API spec.

I've done a quick test and I think it may be possible to generate at least one test per responses of each operation of an API and disable them.

Thanks for the quick help Thibault,

I tried generating test cases for –g spring –library spring-mvc , but still no luck.

Test templates are missing and I don’t know a way to generate test cases.

If you know a hook or workaround to generate spring based test cases using latest stable version then please let me know. Otherwise I will end up using swagger-codegen-cli which does this job without fail.

Is this bug on any roadmap for development? I am a heavy user of the Openapi-Generator and its a feature that is very much needed by my team.

[dbelyaev]

This has been reported in 2019 and now it is a 2023 and still no fix. Please, put it on the development map as this is a useful feature.
