使用Xunit的ServiceBustrigger单元测试

我的azure函数如下。在以下代码中，我将使用存储库中的数据库添加产品＆amp; EF核心。有什么办法可以使用Xunit对其进行测试？目前，我正在使用Azure Service Bus Explorer对此进行测试。

[FunctionName("SaveProductData")]
public void Run([ServiceBusTrigger("mytopicname", Connection = "ServiceBusConnectionString")]
ProductItemUpdate message, ILogger log)
{
    var product = new Domain.Entities.Product()
    {
       ... prop init goes here..... 
    };

    log.LogInformation($"Processed Product - Sain: {message.ProductId}");
    _productRepository.Add(product);
 }

I have an Azure Function as below. In the following code, I'm adding a product to the database using Repository & EF Core. Is there any way we can test it using Xunit? Currently, I'm testing this using Azure Service Bus Explorer.

[FunctionName("SaveProductData")]
public void Run([ServiceBusTrigger("mytopicname", Connection = "ServiceBusConnectionString")]
ProductItemUpdate message, ILogger log)
{
    var product = new Domain.Entities.Product()
    {
       ... prop init goes here..... 
    };

    log.LogInformation(quot;Processed Product - Sain: {message.ProductId}");
    _productRepository.Add(product);
 }

要详细说明ScottdavidWalker的评论，其中有一个完整的示例：

public class SaveProductDataTests
{
    private readonly Mock<IProductRepository> _mockProductRepository = new Mock<IProductRepository>();
    private readonly Mock<ILogger> _mockLogger = new Mock<ILogger>();

    private readonly SaveProductData _saveProductData;

    public SaveProductDataTests()
    {
        _saveProductData = new SaveProductData(_mockProductRepository.Object);
    }

    [Fact]
    public void Given_When_Then()
    {
        // arrange
        var productItemUpdate = new ProductItemUpdate();

        // act
        _saveProductData.Run(productItemUpdate, _mockLogger.Object);

        // assert
        _mockProductRepository.Verify(x => x.Add(It.Is<Product>(p => p.SomeProperty == "xyz")));
    }
}

您需要创建您正在测试的类的实例并模拟依赖关系。

Azure函数本质上是类（.run（））的方法（您可以在实例上调用）。

在您的单元测试中，您创建数据以触发方法，然后在模型上对代码实现时期望发生的事情做出断言。

To elaborate on scottdavidwalker's comment with a full example:

public class SaveProductDataTests
{
    private readonly Mock<IProductRepository> _mockProductRepository = new Mock<IProductRepository>();
    private readonly Mock<ILogger> _mockLogger = new Mock<ILogger>();

    private readonly SaveProductData _saveProductData;

    public SaveProductDataTests()
    {
        _saveProductData = new SaveProductData(_mockProductRepository.Object);
    }

    [Fact]
    public void Given_When_Then()
    {
        // arrange
        var productItemUpdate = new ProductItemUpdate();

        // act
        _saveProductData.Run(productItemUpdate, _mockLogger.Object);

        // assert
        _mockProductRepository.Verify(x => x.Add(It.Is<Product>(p => p.SomeProperty == "xyz")));
    }
}

You need to create an instance of the class you are testing and mock the dependencies.

The Azure function is essentially a method (.Run()) inside the class which you can call on the instance.

In your unit test, you create the data to trigger the method and then make assertions on your mocks for what you expect to happen when the code runs for real.
