# Test-Driven Examples

This page maps concrete examples to test files so behavior can be verified quickly.

## Dynamic Select and Aggregates

Source: `DynamORM.Tests/Select/DynamicAccessTests.cs`

- `Count/Min/Max/Avg/Sum/Scalar`
- `First/Last/Single`
- `IN`, `LIKE`, `BETWEEN`, comparison operators
- ad-hoc column expressions and aliases

## Typed Access and Mapping

Source: `DynamORM.Tests/Select/TypedAccessTests.cs`

- `Query(type: typeof(T))`
- `Execute<T>()`
- projection with `MapEnumerable<T>()`
- table mapping and strongly typed expressions

## SQL Parser and CommandText Expectations

Source: `DynamORM.Tests/Select/ParserTests.cs`

- `From` variants (`schema.table`, aliasing, string forms)
- join expressions and join kind helpers
- subquery embedding
- `NoLock()` translation
- deterministic SQL text generation checks

## Data Modification

Source: `DynamORM.Tests/Modify/DynamicModificationTests.cs`

- insert via named args, anonymous object, mapped class, plain class
- update via key/object/where
- delete via key/object/where

## Schema Variants

Sources:

- `DynamORM.Tests/Modify/DynamicTypeSchemaModificationTests.cs`
- `DynamORM.Tests/Modify/DynamicNoSchemaModificationTests.cs`
- `DynamORM.Tests/Select/DynamicTypeSchemaAccessTests.cs`
- `DynamORM.Tests/Select/DynamicNoSchemaAccessTests.cs`

Use these to validate behavior with and without schema support.

## Resource and Pooling Semantics

Source: `DynamORM.Tests/Helpers/PoolingTests.cs`

- command invalidation after database disposal
- transaction rollback behavior during disposal

## Validation

Source: `DynamORM.Tests/Helpers/Validation/ObjectValidationTest.cs`

- rule-based object validation with `RequiredAttribute`
- array element-level validation

## Dynamic Parser (Helper Layer)

Source: `DynamORM.Tests/Helpers/Dynamic/DynamicParserTests.cs`

Covers lower-level parser behavior used by fluent lambda parsing.
