SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Legacy Struts/JSP applications often lack automated tests, making migrations risky and time‑consuming. This Skill provides structured testing patterns that create safety nets, ensuring behavior is preserved while modernizing the codebase.

Core Features & Use Cases

Characterization Tests: Capture current endpoint behavior and database state before migration.
Action & Controller Testing: Unit‑test Struts 1.x and 2.x actions using mock requests or direct POJOs.
DAO/Repository Tests: Employ in‑memory databases (e.g., H2) for isolated data‑access verification.
Dual‑Run & Contract Testing: Run identical tests against legacy and new endpoints to guarantee functional parity.
Migration Strategy: Provide guidelines for integrating tests into CI pipelines during a shift to modern frameworks.

Quick Start

Ask the skill to create a characterization test for the '/listUsers.do' endpoint.

FAQPage Schema

How do I write characterization tests for legacy Struts actions before migration?▼

Characterization tests for legacy Struts actions capture current endpoint behavior and database state before migration. You generate structured testing patterns using JUnit and mock requests, creating safety nets that ensure behavior is preserved while modernizing the codebase.

Can I test Struts 1.x and Struts 2.x actions using mock requests?▼

Yes, you can unit-test both Struts 1.x and Struts 2.x actions using mock requests or direct POJOs. This approach isolates controller logic and verifies action mappings without deploying the full legacy application to a servlet container.

What is dual-run testing and how does it verify functional parity during framework migration?▼

Dual-run testing executes identical tests against legacy and new endpoints to guarantee functional parity during migration. This contract testing method ensures the modernized framework produces the same outputs and state changes as the original Struts/JSP application.

Do I need an in-memory database like H2 to test legacy DAO layers?▼

Using an in-memory database like H2 for legacy DAO layer tests provides isolated data-access verification. It executes repository tests quickly without relying on external database state, ensuring migration safety nets remain deterministic and repeatable.

What's the best way to integrate migration safety tests into a CI pipeline?▼

Integrating migration safety tests into a CI pipeline requires running characterization and dual-run tests on every commit. This strategy continuously validates that new framework changes preserve the original Struts/JSP endpoint contracts and database behavior throughout modernization.
