From 930b76ecb5f14b51e84f83762aa7ad21e452b858 Mon Sep 17 00:00:00 2001 From: OlgunR Date: Thu, 25 Jun 2026 16:01:33 +0200 Subject: [PATCH] Add ValidatePDF feature with API, Swagger, and tests Implemented the ValidatePDF feature end-to-end: - Added `/api/v1/documents/validate` Minimal API endpoint. - Introduced centralized ExceptionHandlingMiddleware. - Configured Swagger with `AddSwaggerDocumentation` extension. - Enabled XML comments in `DocumentOperator.API.csproj`. - Updated DTOs with XML comments and added `FileSizeMB`. - Added integration tests for the ValidatePDF endpoint (3 tests). - Registered infrastructure services (e.g., `IPdfProcessor`). - Refactored `Program.cs` to include middleware and endpoints. - Updated PHASENPLAN.md and ROADMAP.md to reflect progress. - Cleaned up code and made `Program` accessible for tests. --- .../Configuration/SwaggerConfiguration.cs | 26 ++- .../DocumentOperator.API.csproj | 1 + .../Endpoints/v1/DocumentEndpoints.cs | 65 +++++++- .../Middleware/ExceptionHandlingMiddleware.cs | 122 +++++++++++++- DocumentOperator.API/PHASENPLAN.md | 113 +++++++------ DocumentOperator.API/Program.cs | 31 +++- DocumentOperator.API/ROADMAP.md | 149 ++++++++---------- .../Common/DTOs/ValidatePdfRequest.cs | 4 +- .../Common/DTOs/ValidatePdfResponse.cs | 12 +- .../DependencyInjection.cs | 22 +++ .../DocumentOperator.Tests.csproj | 2 + .../Integration/API/DocumentEndpointsTests.cs | 89 +++++++++++ 12 files changed, 493 insertions(+), 143 deletions(-) create mode 100644 DocumentOperator.Infrastructure/DependencyInjection.cs create mode 100644 DocumentOperator.Tests/Integration/API/DocumentEndpointsTests.cs diff --git a/DocumentOperator.API/Configuration/SwaggerConfiguration.cs b/DocumentOperator.API/Configuration/SwaggerConfiguration.cs index bb2a73f..6185eef 100644 --- a/DocumentOperator.API/Configuration/SwaggerConfiguration.cs +++ b/DocumentOperator.API/Configuration/SwaggerConfiguration.cs @@ -1,6 +1,28 @@ -namespace DocumentOperator.API.Configuration +using Microsoft.OpenApi.Models;
