I tried it. But testing the Shutdown function with mocks wouldn't provide meaningful validation, so we'll add this test as part of our e2e test suite.

@nnnkkk7 I’m not sure if we can easily verify the Shutdown method in E2E tests, but if it’s possible, please do.

Based on my previous implementation in the client provider:
To test the Shutdown() method without an E2E environment, I need an integration test. First, I create a provider and attach it to the OpenFeature SDK. Then, I can call a method to clear all providers from the OpenFeature SDK instance. At that point, I can verify whether our Shutdown method was called and whether it triggered Close() in our Bucketeer Client interface.

Do you think this is possible with Go?

Thank you!
You're right about integration tests. Since we currently only have unit tests with mocks, could we test the Shutdown method call using mocks for this scope? We can add integration tests in a separate PR.🙏
