以下测试在测试元组时会产生错误。
'Assert.AreEqual(test,productRepository.GetById(1))'引发了类型为'NUnit.Framework.AssertionException'的异常
下面介绍的许多解决方案都要求每个模型都具有覆盖等值函数。对于项目中具有200多个模型的软件,这很难维护。是否有任何Nuget软件包或自动代码生成器将为所有200个模型创建相等替代方法?
这些都要求覆盖
NUnit测试
[Test]
public void TestProducts()
{
var options = new DbContextOptionsBuilder<ElectronicsContext>()
.UseInMemoryDatabase(databaseName: "Products Test")
.Options;
using (var context = new ElectronicsContext(options))
{
//DbContextOptionsBuilder<ElectronicsContext> context = new DbContextOptionsBuilder<ElectronicsContext>()
context.Product.Add(new Product { ProductId = 1, ProductName = "TV", ProductDescription = "TV testing", ImageLocation = "test" });
context.SaveChanges();
ProductRepository productRepository = new ProductRepository(context);
var test = new Product
{ProductId = 1, ProductName = "TV", ProductDescription = "TV testing", ImageLocation = "test"};
**//This works**
Assert.AreEqual("TV", productRepository.GetById(1).ProductName);
**//This Fails**
Assert.AreEqual(test,productRepository.GetById(1));
**//This Fails**
Assert.AreEqual(Object.Equals(test, productRepository.GetById(1)), 1);
}
存储库
public class ProductRepository : IProductRepository<Product>
{
private readonly ElectronicsContext _context;
public ProductRepository(ElectronicsContext context)
{
_context = context;
}
public IEnumerable<Product> GetAllProduct()
{
return _context.Product.ToList();
}
public IQueryable<Product> Products => _context.Product;
public Product GetById(int productid)
{
return _context.Product.Find(productid);
}
}
模型
public partial class Product
{
public int ProductId { get; set; }
public string ProductName { get; set; }
public string ProductDescription { get; set; }
public string ImageLocation { get; set; }
public int? ProductCategoryId { get; set; }
public virtual ProductCategory ProductCategory { get; set; }
}

您可能应该检查返回对象的ID。如果引用指针不相等,则尝试测试类是否相同将失败。由于该框架可以使用代理,因此并非总是如此。

尝试使用FluentAssertions nuget软件包(请参见“ Object graph comparison”部分)。
代替
Assert.AreEqual(test,productRepository.GetById(1))
您可以执行以下操作:
test.Should().BeEquivalentTo(productRepository.GetById(1));
