SMS Microservice

The SMS Microservice is a simple microservice that acts as a wrapper around the API for a third-party SMS service. It listens for SendSms commands on a message queue, sends an HTTP request to the third-party SMS service, and then publishes an SmsSent event to a global event bus upon successful SMS delivery.

How to Build and Run the Application

1. Download the Files:

2. Open the solution file:

   • Navigate to the SMSMicroservice directory.
   • Open the SMSMicroservice.sln solution file in Visual Studio.

3. Build the solution:

   • Build the solution by clicking on the "Build" menu and selecting "Build Solution", or by pressing Ctrl+Shift+B.

4. Run the application:

   • Open the Program.cs file in the SMSMicroservice project.
   • Run the Main method.

How to Run Tests

1. Open the solution file:

   • Navigate to the SMSMicroservice directory.
   • Open the SMSMicroservice.sln solution file in Visual Studio.

2. Run the tests:

   • Open the Test Explorer window by clicking on "Test" > "Test Explorer" from the top menu.
   • Run all tests by clicking on "Run All" in the Test Explorer window.

Additional Information

Components Used

• IMessageQueue: Interface for the message queue.
• IEventBus: Interface for the event bus.
• ILogger: Interface for the logger.
• MessageQueue: Concrete implementation of IMessageQueue.
• EventBus: Concrete implementation of IEventBus.
• ConsoleLogger: Concrete implementation of ILogger.
• SendSmsCommand: Command class for sending SMS.
