Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00154 | $0.02401 |
| Opus 5.5 | $0.00062 | $0.00960 |
| Sonnet 5.5 | $0.00031 | $0.00480 |
| Haiku 4.5 | $0.00015 | $0.00240 |
Grade A, and why
dotnet-testing-advanced-webapi-integration-testing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 22d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

WebApi 整合測試
學習目標
完成本技能學習後，您將能夠：
- 建立完整的 WebApi 整合測試架構
- 使用
IExceptionHandler實作現代化異常處理 - 驗證
ProblemDetails和ValidationProblemDetails標準格式 - 使用 Flurl 簡化 HTTP 測試的 URL 建構
- 使用 AwesomeAssertions 進行精確的 HTTP 回應驗證
- 建立多容器 (PostgreSQL + Redis) 測試環境
核心概念
IExceptionHandler - 現代化異常處理
ASP.NET Core 8+ 引入的 IExceptionHandler 介面提供了比傳統 middleware 更優雅的錯誤處理方式。GlobalExceptionHandler 依據例外類型（KeyNotFoundException → 404、ArgumentException → 400、其他 → 500）產生對應的 ProblemDetails 回應。
ProblemDetails 標準格式
RFC 7807 定義的統一錯誤回應格式：
| 欄位 | 說明 |
|---|---|
type |
問題類型的 URI |
title |
簡短的錯誤描述 |
status |
HTTP 狀態碼 |
detail |
詳細的錯誤說明 |
instance |
發生問題的實例 URI |
ValidationProblemDetails - 驗證錯誤專用
繼承自 ProblemDetails，額外包含 errors 字典，記錄每個欄位的驗證錯誤訊息。
FluentValidation 異常處理器
FluentValidation 異常處理器實作 IExceptionHandler 介面，專門處理 ValidationException，將驗證錯誤轉換為標準的 ValidationProblemDetails 格式回應。處理器之間按照註冊順序執行，特定處理器（如 FluentValidation）必須在全域處理器之前註冊。
完整實作程式碼請參閱 references/exception-handler-details.md
整合測試基礎設施
測試基礎設施由三個核心組件構成：
-
TestWebApplicationFactory：繼承
WebApplicationFactory<Program>，配置多容器（PostgreSQL + Redis）與 DI 替換（如 FakeTimeProvider）FakeTimeProvider由 Collection 內所有測試共用，只能往前推；不要在每個測試開始時設回固定起點，時間斷言改以Factory.TimeProvider.GetUtcNow()推算。 -
IntegrationTestCollection：Collection Fixture 定義，確保容器共享
-
IntegrationTestBase：測試基底類別，提供 HttpClient、DatabaseManager、FlurlClient 與時間控制方法
完整基礎設施程式碼請參閱 references/test-infrastructure.md
Flurl 簡化 URL 建構
// 傳統方式
var url = $"/products?pageSize={pageSize}&page={page}&keyword={keyword}";
// 使用 Flurl
var url = "/products"
.SetQueryParam("pageSize", 5)
.SetQueryParam("page", 2)
.SetQueryParam("keyword", "特殊");
測試範例
涵蓋成功建立產品（201 Created）、驗證錯誤（400 BadRequest + ValidationProblemDetails）、資源不存在（404 NotFound + ProblemDetails）、分頁查詢（200 OK + PagedResult）等完整測試範例，以及 TestHelpers 資料管理策略。

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

dotnet-testing-advanced-webapi-integration-testing is a skill published in the GitHub repository kevintsengtw/dotnet-testing-agent-skills (30 stars, last pushed 18d ago), licensed MIT. It adds 154 tokens to every session and 2,401 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
