This database is in general **not suitable as a substitute for testing applications that use EF Core**. Specifically: + * It is not a relational database. * It doesn't support transactions. +* It cannot run raw SQL queries. * It is not optimized for performance. None of this is very important when testing EF Core internals because we use it specifically where the database is irrelevant to the test.
