Entity Framework Core Interview Question #178

When is SQLite useful for EF Core testing?

Testing, Production Practices & Senior Real-World Scenarios Senior Advanced

Quick Interview Answer

SQLite can provide fast relational tests and supports more relational behavior than the InMemory provider. It is useful when the production behavior being tested is portable across providers. However, SQLite differs from SQL Server, PostgreSQL, and other engines in types, SQL functions, concurrency, migrations, and provider-specific features, so critical provider-specific behavior should be tested against the real engine.
