feat(pubsub/azure/servicebus/queues): add certification tests

[jmfloreszazo]

Description

This pull request introduces a certification test suite for the Azure Service Bus Queues pub/sub component (pubsub.azure.servicebus.queues) in the components-contrib repository.

The goal is to provide reproducible automated tests that validate both basic and advanced functionality, enabling this component to be promoted from Beta to Stable as required by the project’s certification lifecycle.

The tests cover core pub/sub semantics (competing consumers, multiple subscriptions, queue auto-creation) and outline additional scenarios for resilience, metadata handling, authentication, and edge cases. The suite is intended to run against a real Azure Service Bus namespace using environment variables for configuration.

Documentation (README) is included to explain environment setup and how to execute the tests locally.

Issue reference

#2940 – Azure Service Bus queues pubsub component as stable

Checklist

• Code compiles correctly
• Created tests
• Added a certification test suite for pubsub.azure.servicebus.queues
• Tests can be run via go test ./components-contrib/tests/conformance/pubsub/azure_servicebus_queues -v
• Extended the documentation
  • Created README.md inside tests/conformance/pubsub/azure_servicebus_queues/ explaining:
    • required environment variables
    • test plan coverage
    • how to run tests
• Update Azure Service Bus Queues state from Beta to Stable #4992

Additional Context

Auto-created Queues

The queues used in tests (auto-created) are:

• certification-pubsub-queue-active
• certification-pubsub-queue-passive
• certification-queue-per-test-run (and variants with UUID suffix used by tests that require unique queues, e.g. certification-queue-per-test-run-)

Quick notes:

• Tests auto-create queues unless entity management is disabled.
• The EntityManagement test expects the queue NOT to exist (it uses unique names to avoid collisions).

Environment Variables

The following environment variables are expected when running the certification test suite:

# Basic authentication
export AzureServiceBusConnectionString="Endpoint=sb://<namespace>.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=<key>"

# Azure AD authentication (for TestServicebusQueuesAuthentication)
export AzureServiceBusNamespace="<namespace>.servicebus.windows.net"
export AzureCertificationTenantId="<tenant-id>"
export AzureCertificationServicePrincipalClientId="<client-id>"
export AzureCertificationServicePrincipalClientSecret="<client-secret>"

Run tests

cd tests/certification/pubsub/azure/servicebus/queues
go test -v -timeout 30m
