我有一个关于测试我的应用程序的问题,我在其中使用消息代理(公共交通库、Azure 服务总线实现)在服务之间进行通信。假设我有 ServiceA 和 ServiceB。
就集成测试而言,我想很明显我只是启动 ServiceB 和 Message Broker 并进行测试。但是,我更多地想是否有与消息代理进行合同测试之类的事情?我尝试搜索和谷歌搜索,但找不到任何东西。
提前非常感谢。
编辑: ServiceA - 此方法通过公共交通主题消息发送
public async Task Send()
{
await _publishEndpoint.Publish(new TestMessage(), cancellationToken);
}
ServiceB - 这是 TestMessage 的使用者
public class TestConsumer : IConsumer<TestMessage>
{
public async Task Consume(ConsumeContext<TestMessage> context)
{
// Do some work
}
}
以下代码适用于 ServiceA 和 ServiceB 以及集成测试,以使用 Azure 服务总线和 MassTransit 来测试它们之间的消息流:
{
var busControl = Bus.Factory.CreateUsingAzureServiceBus(cfg =>
{
cfg.Host("your-connection-string");
});
await busControl.StartAsync();
var serviceA = new ServiceA(busControl);
await serviceA.Send();
await busControl.StopAsync();
}
}
public class ServiceA
{
private readonly IBusControl _busControl;
public ServiceA(IBusControl busControl)
{
_busControl = busControl;
}
public async Task Send()
{
await _busControl.Publish(new TestMessage { Content = "Hello from ServiceA!" });
Console.WriteLine("Message sent from ServiceA");
}
}
public class TestMessage
{
public string Content { get; set; }
}
测试用例:
[Test]
public async Task TestMessageFlow()
{
// Arrange
var busControl = Bus.Factory.CreateUsingAzureServiceBus(cfg =>
{
cfg.Host("your-connection-string");
});
await busControl.StartAsync();
var serviceA = new ServiceA(busControl);
var serviceB = new ServiceB(busControl);
// Act
await serviceB.StartListening();
await serviceA.Send();
// Assert
// You can add assertions here to verify that ServiceB has received and processed the message
// For example, check logs, database state, etc.
await busControl.StopAsync();
}
}
public class ServiceA
{
private readonly IBusControl _busControl;
public ServiceA(IBusControl busControl)
{
_busControl = busControl;
}
public async Task Send()
{
await _busControl.Publish(new TestMessage { Content = "Hello from ServiceA!" });
}
}
