You can compare complex nested object graphs in .NET tests using FluentAssertions' BeEquivalentTo API, which performs deep validation across entire object structures. It automatically traverses nested properties to verify equivalence without requiring exact reference matches.

Excluding specific properties like timestamps during .NET object comparison is done using FluentAssertions' BeEquivalentTo API with exclusion rules. You configure the assertion to ignore fields like CreatedAt or auto-generated database values, ensuring selective comparison only validates relevant fields.

Yes, FluentAssertions' BeEquivalentTo API safely handles circular references during deep object comparison. It detects recursive structures within object graphs and validates them without throwing stack overflow exceptions, ensuring reliable validation of complex interconnected entities.

The best way to validate complex DTOs against expected values in .NET testing is leveraging deep object comparison via BeEquivalentTo. This approach verifies all relevant nested fields match while allowing you to exclude database-specific fields, facilitating accurate Entity and DTO validation.

Yes, deep object comparison in .NET supports selective property inclusion and exclusion through FluentAssertions' BeEquivalentTo configuration. You can specify exactly which fields to include or exclude, allowing targeted validation of complex objects while ignoring navigation properties or auto-generated fields.
