From 8e699c9637af316a46d76b12eb8c8a60b828330f Mon Sep 17 00:00:00 2001 From: Nick Cipollina Date: Thu, 3 Jul 2025 16:19:06 -0400 Subject: [PATCH] Add IStackProps overloads to CdkTestHelper for custom stack configurations MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary - Added overload methods to support custom IStackProps implementations - Enhanced testing flexibility for real-world scenarios with custom stack properties - Added comprehensive test coverage for new overload methods ## Changes Made ### ✨ New Features - **CdkTestHelper.CreateTestStack(string, IStackProps)**: Creates test stack with custom props - **CdkTestHelper.CreateTestStackMinimal(string, IStackProps)**: Creates minimal test stack with custom props ### 🧪 Test Coverage - Added tests for custom environment settings (account, region) - Added tests for custom tags and descriptions - Added real-world integration test simulating LightsaberStackProps usage pattern ## Benefits - **Flexible Stack Configuration**: Supports any IStackProps implementation - **Real-World Usage**: Enables testing with custom stack props like LightsaberStackProps - **Maintains Simplicity**: Reduces boilerplate while supporting complex scenarios - **Backward Compatible**: Existing code continues to work unchanged ## Usage Example ```csharp var customProps = new LightsaberStackProps { Env = env, Context = context, Tags = tags }; var stack = CdkTestHelper.CreateTestStackMinimal("test-stack", customProps); var template = Template.FromStack(stack); ``` 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .../Testing/CdkTestHelper.cs | 28 ++++++ .../Testing/TestingHelpersTests.cs | 89 +++++++++++++++++++ 2 files changed, 117 insertions(+) diff --git a/src/LayeredCraft.Cdk.Constructs/Testing/CdkTestHelper.cs b/src/LayeredCraft.Cdk.Constructs/Testing/CdkTestHelper.cs index c6ef270..ad81363 100644 --- a/src/LayeredCraft.Cdk.Constructs/Testing/CdkTestHelper.cs +++ b/src/LayeredCraft.Cdk.Constructs/Testing/CdkTestHelper.cs @@ -35,6 +35,21 @@ public static (App app, Stack stack) CreateTestStack( return (app, stack);
