使用 Docker 集成测试 Azure 服务总线

Question

What is an appropriate way to integration test systems that use ASB? With something like Kafka and using docker-compose, I could spin up two services that will communicate asynchronously over Kafka. Is there a way to do something similar with ASB? If not, what is a common integration testing pattern?

Answer 1

The pricing model for Service Bus has 12.5 million operations per month included for free . Past that, it's less than a dollar per millions of messages sent. With these kinds of services it should be simple for you to spin up and tear down instances with absolutely zero cost to you as part of integration tests.

NUnit, for example provides the [OneTimeSetup] and [OneTimeTearDown] methods which you could use as part of an integration test suite to provision and subsequently delete a Service Bus instance.

Answer 2

Sadly, I don't think Azure Storage Emulator supports the service bus yet, but you could extract the functionality to an interface and either write a fake ASB and use that or have the interface use the queue in the Emulator. If you want to use the actual ASB and don't mind incurring costs, you could spin up a new one with a guid for a name or if create evanescent queues or topics/subscriptions with guids for their names as well, then tear it all down when you're done.

Not ideal perhaps, but it gives you some options. Perhaps if you shared more detail about what you're using ASB for, we could offer better solutions.

Answer 3

There is a Azure Storage Emulator Docker Image in docker hub. When using it, remember that you must use Windows emulation:

given image can be used in docker compose:

version: '3.7'

services:
    azure_sb:
        container_name: azure_sb
        image: microsoft/azure-storage-emulator
        tty: true
        restart: always
        ports:
            - "10000:10000"
            - "10001:10001"
            - "10002:10002"

For test or dev usages considec using lightway version of it which is Azurite link to doc

version: '3.7'

services:
    azurite:
        container_name: azurite
        image: mcr.microsoft.com/azure-storage/azurite
        tty: true
        restart: always
        ports:
            - "10000:10000"
            - "10001:10001"
