From 15bff2e11dd42485e2ed11f776a0d71aba718c83 Mon Sep 17 00:00:00 2001 From: Yuriy Bezsonov Date: Fri, 3 Jul 2026 11:20:41 +0200 Subject: [PATCH 1/3] test(cdk): Drop jqwik; use JUnit parameterized test jqwik was used for a single "property" whose input space was just the three IdeArch enum values - equivalent to a JUnit @ParameterizedTest with @EnumSource, and with no extra dependency. - Convert IdePropsTest.architectureDeterminesInstanceTypes to @ParameterizedTest + @EnumSource(IdeArch.class). - Remove the net.jqwik:jqwik-engine test dependency. - Remove the now-unused .jqwik-database .gitignore entry. Also removes the jqwik-engine 1.10.1 anti-AI-agent banner it printed to test stdout during synth.

The previous enumerated appliesTo lists only matched the default template's findings, so cdk synth failed with 87 uncovered AwsSolutions-IAM4/IAM5 errors (Ide/UserPolicy, WorkshopBoundary, EKS, Unicorn, ThreadAnalysis, AiJvmAnalyzer, PerfPlatform roles). Replace the brittle enumerated appliesTo with RegexAppliesTo so the suppressions match every IAM4 (Policy::*) and IAM5 (Action::* / Resource::*) finding, robust across all template types and generated resource names. Broad IAM is intentional for the ephemeral workshop environment.
