Write unit and integration tests for Salvo applications using TestClient. Use for testing handlers, middleware, and API endpoints.
Write and maintain tests with Vitest v4 dual configuration, mock utilities, and Zustand store testing patterns.
Use this skill when you need to write, review, or debug automated tests for applications built on the Jazz framework. This skill provides the correct architectural patterns for simulating local-first synchronization and multi-user environments without resorting to invalid mocking strategies.
Ensure code correctness with comprehensive unit and integration tests.
Pairs trading / statistical-arbitrage strategy via Longbridge Securities — tests cointegration between two correlated assets using the Engle-Granger (ADF) method, computes the optimal hedge ratio via OLS, calculates spread Z-score, half-life of mean reversion, and generates entry/exit signals (long spread when Z > 2, short spread when Z < -2, exit when |Z| < 0.5). Triggers: "配对交易", "统计套利", "协整", "价差交易", "对价交易", "双股套利", "配對交易", "統計套利", "協整", "價差交易", "pairs trading", "statistical arbitrage", "cointegration", "spread trading", "mean reversion pairs", "hedge ratio", "half-life", "ADF test", "Kalman filter", "Z-score spread", "spread mean reversion".
Test email sending locally using Mailpit with .NET Aspire. Captures all outgoing emails without sending them. View rendered HTML, inspect headers, and verify delivery in integration tests.
Test coverage-focused code review. Apply when reviewing code for missing unit tests, integration tests, edge cases, error handling paths, test quality, and test maintainability.
Emulated Slack API for local development and testing. Use when the user needs to interact with Slack API endpoints locally, test Slack integrations, emulate channels/messages/users, set up Slack OAuth flows, test incoming webhooks, or work with the Slack Web API without hitting the real Slack API. Triggers include "Slack API", "emulate Slack", "mock Slack", "test Slack OAuth", "Slack bot", "incoming webhook", "local Slack", or any task requiring a local Slack API.
Use when designing tests, writing test cases, or planning test strategy for a module. Covers unit, integration, and e2e layering.
Run Firefox mach try commands with pre-configured flags for os-integration testing on Windows and Linux alpha worker pools. Use when testing Firefox changes against Windows 10, Windows 11, Ubuntu 24.04, hardware workers, ARM64, or AMD configurations. Triggers on "os-integration", "mach try", "windows testing", "linux testing", "alpha image".
[Testing] Use when creating or enhancing unit tests, integration tests, or defining test strategies for backend and frontend code.
Designs and implements testing strategies for any codebase. Use when adding tests, improving coverage, setting up testing infrastructure, debugging test failures, or when asked about unit tests, integration tests, or E2E testing.
