Skill UI

Provides an expert Spring Boot 4 testing guide that explains the test pyramid, slice annotations, AssertJ-centric assertions, MockMvcTester, RestTestClient, Testcontainers, and practical coverage goals.

This skill systematically reviews test code to identify and correct common anti-patterns. It detects issues such as flaky tests, overly mocked dependencies (over-mocking), brittle assertions, excessive test size (The Giant), and structural dependencies. It explains the flaw, provides best practices, and suggests refactored, reliable implementations, helping maintain high test quality and stability.

A comprehensive guide for writing and reviewing robust, behavior-first unit tests for Vue 3, TypeScript, and Pinia stores. This skill covers advanced patterns for testing components, composables, and state management using Vitest and Vue Test Utils, emphasizing black-box assertions and minimizing implementation coupling.

This guide details migrating outdated and unsafe `as` type assertions in TypeScript test files. It introduces `@total-typescript/shoehorn`, which provides type-safe functions like `fromPartial()` and `fromAny()`. Use this utility when unit tests need to mock large objects or pass only a subset of required data, thereby maintaining strict type checking and improving test robustness. Note: This is strictly for test code.

This skill provides a comprehensive playbook for testing the security of SAML-based Single Sign-On (SSO) solutions. It focuses on validating assertion trust by checking signature coverage, audience and recipient restrictions, handling of Assertion Consumer Service (ACS), and identifying potential XML parsing weaknesses or IdP/SP confusion flaws. Use this when evaluating enterprise authentication systems for critical security vulnerabilities.

This skill automates end-to-end (E2E) functional testing for Android applications. It parses an XML specification defining a multi-step user 'journey.' The executor sequentially performs interactive UI actions (taps, swipes, text input) using ADB commands and verifies application states through assertions. It outputs a detailed, standardized JSON report, making it ideal for robust CI/CD integration and quality assurance.

This sophisticated skill is designed to locate the root cause of a confirmed software failure. It performs a systematic, semi-formal tracing process: first tracing backward from the observed failure point (using provided stack traces, assertions, or error messages) to identify the original premise, and then tracing forward to confirm the symptom. It outputs a highly structured report detailing the divergence, premises, and remedy.
