End-User Verification Testing

Overview

Execute verification tasks that validate real infrastructure behavior through structured Setup/Action/Assert sequences. Classify tasks at runtime (CLI/GUI/SUBJECTIVE) to determine whether to auto-approve or present human checkpoints. This skill transforms tasks marked with **TEST:** into executable verification sequences with captured evidence.

Violating the letter of the rules is violating the spirit of the rules.

Verification testing exists to catch failures before they reach production. Every shortcut in this process is a potential production incident waiting to happen.

When to Use

• Tasks marked with **TEST:**, **TEST:VERIFY**, or **TEST:CONTRACT**
• Legacy **HUMAN VERIFICATION** tasks (mapped to unified format)
• CLI command verification with expected output
• File system state validation
• Real process behavior testing (not mocks)
• GUI/UI verification requiring human judgment
• End-to-end validation before deployment

When NOT to Use

• Unit tests that run in isolation
• Mock-based testing without infrastructure
• Static code analysis tasks
• Documentation review tasks
• Tasks without clear pass/fail criteria
• When verification environment is unavailable

Core Process

Task Detection

Identify tasks containing verification markers:

- [ ] **TN.X**: **TEST:** - {Description}
  - **Setup**: {Prerequisites} (optional)
  - **Action**: {Command or instruction}
  - **Assert**: {Expected outcome}
  - **Capture**: {console, screenshot, logs} (optional)

Supported markers (all normalized to unified format):

• **TEST:** - Unified format (preferred)
• **TEST:VERIFY** - Legacy format
• **TEST:CONTRACT** - Legacy format
• **HUMAN VERIFICATION** - Legacy format (maps Setup/Action/Verify fields)

See references/TASK-PARSING.md for field marker extraction rules.

Execution Sequence

Execute in strict order. No skipping steps. No reordering.

1. Parse Task

Extract structured data:

• Task ID (T{N}.{X})
• Test type (VERIFY or CONTRACT)
• Setup commands
• Actions with modifiers
• Assert conditions
• Capture requirements
• Human review criteria

2. Execute Setup

Run setup commands sequentially. Fail fast if any setup fails. Record all output for debugging. Setup failures block action execution.

3. Execute Actions

Run each action respecting modifiers:

Modifier	Example	Behavior
(background)	npm start (background)	Run async, track PID
(timeout Ns)	curl ... (timeout 10s)	Override 60s default
(in {path})	make build (in ./backend)	Change directory

Capture all console output. Track background processes. Enforce timeouts. See references/EVIDENCE-CAPTURE.md for capture details.

4. Evaluate Asserts

Check each assert against captured evidence:

Pattern	Verification
Console contains "{text}"	Substring match
Console contains "{text}" (within Ns)	Timed match
File exists: {path}	test -f {path}
Response status: {code}	HTTP status check

5. Generate Report

• All PASS: Minimal report (status + duration)
• Any FAIL: Rich report with evidence table

See references/REPORT-TEMPLATES.md for templates.

6. Present Checkpoint

Ask human to approve, reject, or retry. Human decision gates cycle completion. No proceeding without explicit human approval.

Task Classification

Before execution, classify the task based on Action and Assert content:

Classification	Criteria	Checkpoint Behavior
CLI	Backtick commands + measurable asserts	May auto-approve if 100% pass
GUI	UI actions (click, tap) or screenshot capture	Always human checkpoint
SUBJECTIVE	Qualitative terms (looks, feels, appears)	Always human checkpoint

Default to SUBJECTIVE if uncertain (safe fallback).

Result Classification

Status	Meaning
PASS	All asserts passed
FAIL	One or more asserts failed
PARTIAL	Mixed results, needs judgment
TIMEOUT	Action exceeded time limit
ERROR	Execution error (not assertion)

Evidence Types

Type	Capture Method
console	stdout/stderr from commands
screenshot	Platform-specific screen capture
logs	Contents of specified log files
timing	Duration of each action

Quality Gates

Before presenting checkpoint, verify completion of ALL items:

• All setup commands completed
• All actions executed (or timed out)
• All asserts evaluated
• Evidence captured per Capture field
• Report generated with proper detail level

No presenting partial results. No skipping evidence capture. No proceeding without human approval.

No exceptions:

• Not for "simple tests that obviously pass"
• Not if the user seems impatient
• Not if evidence capture is slow
• Not even if setup was identical to previous run
• Not even if "just checking one thing"

Red Flags - STOP and Restart Properly

If any of these thoughts arise, STOP immediately:

• "The test obviously passed, no need for full evidence capture"
• "I already know this works from previous runs"
• "Just a quick verification, minimal report is fine"
• "The user seems impatient, skip to the result"
• "This is a simple test, full process is overkill"
• "Evidence capture is taking too long"
• "I can infer the result without running the test"
• "The setup is the same as last time"

All of these mean: Rationalization in progress. Return to the execution sequence. Follow every step.

Common Rationalizations

Excuse	Reality
"Test obviously passed"	Obvious passes hide subtle failures. Capture evidence anyway.
"Already ran this before"	Previous runs are stale. Each execution is independent. Run again.
"User wants quick answer"	Quick answers without evidence are unreliable. Process protects user.
"Simple test case"	Simple tests catch complex bugs. Full process regardless of simplicity.
"Evidence capture is slow"	Slow capture beats fast wrong answer. Time investment protects quality.
"Can infer the result"	Inference is not verification. Execute and observe.
"Same setup as before"	Environments change. Run setup fresh. Validate assumptions.
"Just checking one thing"	One thing has dependencies. Full sequence catches hidden failures.

Common Mistakes

Mistake: Skipping Setup Validation

What goes wrong: Action fails mysteriously because setup was assumed complete.

Fix: Always run setup commands. Always capture setup output. Fail explicitly if setup fails.

Mistake: Missing Background Process Cleanup

What goes wrong: Background processes from previous tests interfere with current test.

Fix: Track all PIDs. Kill processes after test (pass or fail). Verify cleanup completed.

Mistake: Truncating Evidence Prematurely

What goes wrong: Critical failure information cut off from report.

Fix: Follow truncation rules in REPORT-TEMPLATES.md. Always include log file locations. Preserve full evidence for human review.

Mistake: Reporting PASS Without Assert Verification

What goes wrong: Claiming PASS when asserts were not actually evaluated.

Fix: Each assert MUST have an explicit pass/fail evaluation. No default to PASS. Unevaluated asserts are failures.

Mistake: Proceeding After Rejected Checkpoint

What goes wrong: Continuing execution when human explicitly rejected.

Fix: Rejection gates completion. Human approval is mandatory. Retry or abort on rejection.

Mistake: Skipping Checkpoint Presentation

What goes wrong: Test runs but human never sees results. No audit trail. No approval gate.

Fix: Every test MUST end with checkpoint presentation. No silent completion. Human-in-loop is the point.
