My DbSet is required. I’d like to create test using InMemoryDatabase. However when I instantiate context I’m getting an error

Error (active)  CS9035  Required member 'TestContext.Users' must be set in the object initializer or attribute constructor.

Below my code:

    public class TestContext : DbContext
    {
        public virtual required DbSet<User> Users { get; set; }

        public TestContext(DbContextOptions<TestContext> options) : base(options)
        {

        }
    }

    public class UserTests
    {
        public UserTests()
        {
            var options = new DbContextOptionsBuilder<TestContext>()
                .UseInMemoryDatabase(Guid.NewGuid().ToString())
                .Options;


            TestContext testContext = new TestContext(options);
        }
    }

I tried to set Users property using initializer like this:

new TestContext(options) { Users = null}

but of course it sets DbSet to null which is not what I want to achieve. I also inherited abstract class DbSet but then I’d need to implement this class and I want to avoid that. I also tried to inherit Context but inherited properties also need to be required.

Is it a way to instantiate context without explicitly setting DbSets (please note that I’d like to keep required for DbSets, I also don’t want to use any mocking frameworks)?
