使用DB context和inMemoryDb的POST方法的C#单元测试

Install-Package Microsoft.EntityFrameworkCore
Install-Package Microsoft.EntityFrameworkCore.InMemory

public class MyDbContext : DbContext
{
    public DbSet<User> Users { get; set; }

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        optionsBuilder.UseInMemoryDatabase("TestDatabase");
    }
}

public class User
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Email { get; set; }
}

[TestMethod]
public void TestPostMethod()
{
    // Arrange
    var options = new DbContextOptionsBuilder<MyDbContext>()
        .UseInMemoryDatabase(databaseName: "TestDatabase")
        .Options;

    using (var context = new MyDbContext(options))
    {
        var service = new UserService(context);
        var user = new User { Name = "John", Email = "john@example.com" };

        // Act
        service.AddUser(user);

        // Assert
        Assert.AreEqual(1, context.Users.Count());
        Assert.AreEqual("John", context.Users.Single().Name);
        Assert.AreEqual("john@example.com", context.Users.Single().Email);
    }
}
