All 13 spec examples and 5 blog scenarios now validate SQL patterns instead of in-memory computation. 89 tests pass. Build and format clean.

All aggregation is performed by the database. -- **COUNT(\*) workaround.** The engine's `Build(AggregationColumn)` doesn't support `*` as a column name (it produces invalid SQL like `count([].[*])`), so the primary key column is used instead. `COUNT(pk)` ≡ `COUNT(*)` since PK is NOT NULL. -- **ORDER BY post-processing.** Neither the GraphQL nor REST code paths support ORDER BY on an aggregate expression, so this tool inserts `ORDER BY {func}({col}) ASC|DESC` into the generated SQL before `FOR JSON PATH`. -- **TOP vs OFFSET/FETCH.** SQL Server forbids both in the same query. When pagination (`first`) is used, `TOP N` is stripped via regex before appending `OFFSET/FETCH NEXT`. -- **Early field validation.** All user-supplied field names (aggregation field, groupby fields) are validated against the entity's metadata before authorization or query building, so typos surface immediately with actionable guidance. -- **Timeout vs cancellation.** `TimeoutException` (from `query-timeout` config) and `OperationCanceledException` (from client disconnect) are handled separately with distinct model-facing messages. Timeouts guide the model to narrow filters or paginate; cancellations suggest retry. -- **Database support.** Only MsSql / DWSQL — matches the engine's GraphQL aggregation support. PostgreSQL, MySQL, and CosmosDB return an `UnsupportedDatabase` error. diff --git a/src/Service.Tests/Mcp/AggregateRecordsToolTests.cs b/src/Service.Tests/Mcp/AggregateRecordsToolTests.cs index 7fa97fa2fe..f198e9b595 100644 --- a/src/Service.Tests/Mcp/AggregateRecordsToolTests.cs +++ b/src/Service.Tests/Mcp/AggregateRecordsToolTests.cs @@ -23,15 +23,10 @@ namespace Azure.DataApiBuilder.Service.Tests.Mcp { /// - /// Tests for the AggregateRecordsTool MCP tool. - /// Covers: - /// - Tool metadata and schema validation - /// - Runtime-level enabled/disabled configuration - /// - Entity-level DML tool configuration - /// - Input validation (missing/invalid arguments) - /// - SQL expression generation (count, avg, sum, min, max, distinct) - /// - Table reference quoting, cursor/pagination logic - /// - Alias convention + /// Integration tests for the AggregateRecordsTool MCP tool. + /// Covers tool metadata/schema, configuration, input validation, + /// alias conventions, cursor/pagination, timeout/cancellation, spec examples, + /// and blog scenario validation. /// [TestClass] public class AggregateRecordsToolTests @@ -39,29 +34,26 @@ public class AggregateRecordsToolTests #region Tool Metadata Tests [TestMethod] - public void GetToolMetadata_ReturnsCorrectName() + public void GetToolMetadata_ReturnsCorrectNameAndType() { AggregateRecordsTool tool = new();
