test-engine

test-engine is a skill for Claude Code from korchard333/claude-power-platform-community. It costs 48 tokens per session (1,213 once invoked), scanned A, original, MIT.

A testing toolkit for Microsoft Power Platform apps, using Power Apps Test Engine and Playwright to check how apps work through their user interface.

In plain words
What is it for?
It helps test Canvas Apps, Model-Driven Apps, and Power Pages, including standard controls, custom interfaces, third-party components, and visual changes in automated pipelines.
Why use it?
It reduces the need to repeat end-to-end checks by hand and helps catch regressions after changes or deployments.

Token cost

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.

Security

Grade A, and why

test-engine 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 9d 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.

Skill: Power Apps Test Engine + Playwright

When to Use

Trigger when testing Power Platform apps end-to-end, writing automated test plans, setting up test pipelines, or verifying UI after deployment.

Decision Matrix: Which Testing Approach?

Approach When Language Selectors Auth
Test Engine (Power Fx YAML) Standard Canvas/MDA testing, low-code teams Power Fx in YAML App-level control names Built-in Entra handling
Raw Playwright (TypeScript) Complex UI, custom controls, third-party components, visual QA TypeScript or C# CSS/XPath DOM selectors Manual auth scripting
Test Engine + Playwright hybrid Standard tests with occasional DOM access Power Fx + Preview.PlaywrightAction() Both Built-in + direct
Manual testing One-off verification, exploratory testing N/A N/A N/A

Rule of thumb: Start with Test Engine Power Fx for standard apps. Drop to raw Playwright only when Test Engine abstractions can't reach what you need (custom controls, third-party embedded UIs, visual regression).

AI Accuracy Warning

LLMs are less accurate with Power Fx than mainstream languages (JavaScript, C#, Python) due to smaller training datasets. Always verify Power Fx test steps manually before trusting them in CI/CD. This applies to both test authoring and formula column definitions.

⚠️ REQUIRED: Load Sub-Files Before Implementation

SKILL.md is a summary only — it is NOT sufficient for implementation.

The detailed content (complete payloads, XML templates, working examples, edge-case handling) lives in sub-files in the same directory as this SKILL.md. Before writing any code, you MUST use read_file on the sub-files relevant to your task:

  • Test Plans (YAML Format) — YAML schema, Power Fx test steps, assertions, credentials, recording video
  • Canvas App Testing — Canvas provider, control name selectors, gallery navigation, delegation testing
  • Model-Driven App Testing — MDA provider, form verification, view checks, BPF testing, Dataverse integration
  • Playwright Advanced — Direct Playwright functions, custom C# scripts, raw TypeScript tests, Sean Astrakhan's AI-generated test pattern
  • CI/CD Integration — ADO pipeline YAML, GitHub Actions, publishing .trx results, regression testing on every deploy
  • Power Pages Testing — Portal provider, auth testing, table permission verification, Web API testing

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.
