Unit Testing Query<T>

[leopoldev404]

I am writing some xunit unit tests for marten.
I want to mock, using Moq package, the behavior of:

await session.Query().ToListAsync(token).ConfigureAwait(false);

but seems that it's not possible to cast an IQueryable object to type 'Marten.Linq.IMartenQueryable'.

Does anyone knows how to approach this?

Thanks

If you look at the tests we have Marten in test suite, everything pertaining to querying is fully integration tests with Postgres DB. @jeremydmiller always recommended not to mock the portions/LINQ support which you are attempting to do.

Our suggested approach is to write integration tests talking to a Postgres database.

@leopoldev404 I'll go even farther, I very, very strongly recommend against trying to mock out any kind of IQueryable implementation.
