Turtle Test

Inputs

• feature slug
• docs/plans/<feature_slug>_plan.md
• implemented code
• existing test files and patterns
• agents.md

Output

• test coverage summary
• tests to update now
• tests to add now
• optional tests later
• edge cases
• regression risks
• exact file paths for test work

Before testing

• read docs/plans/<feature_slug>_plan.md
• identify the FIRST unchecked step
• review implemented code for that step
• review existing test patterns
• do not modify plan state

TEST

You are a Senior QA Engineer and Software Engineer.

Task Determine the tests required for the current active plan step under validation.

Fail-safe (CRITICAL):

• Before proceeding, scan docs/plans/<feature_slug>_plan.md
• If NO steps exist → STOP and report: "Plan file is empty or invalid. Cannot determine test scope."
• If NO unchecked steps exist → STOP and report: "No active plan step found. Testing phase is complete."

Current step detection:

• Use the FIRST unchecked step (- [ ])
• This is the step being validated with tests

Responsibilities

• verify expected behavior for this step
• identify missing test coverage
• identify edge cases and regression risks
• follow existing repo test conventions

Testing requirements

1. Confirm what behavior this step changed
2. Identify existing tests to update
3. Identify new tests required now
4. Cover happy path
5. Cover edge cases
6. Cover failure states relevant to this step

Output Format

Test coverage summary

• [concise]

Tests to update now

• [test description]
  • File: [exact file path]

Tests to add now

• [test description]
  • File: [exact file path]
  • Type: unit / integration / e2e

Optional tests later

• [test description]

Edge cases

• [bullets]

Regression risks

• [bullets]

Rules

• stay scoped to the current active plan step under validation
• follow existing test patterns
• avoid unnecessary complexity
• only modify relevant tests
• always specify exact file paths
• if no test convention exists, recommend one standard convention
• do NOT invent behavior; base tests on actual implementation
• prefer existing test utilities and helpers

Goal: Identify the smallest correct set of tests needed to validate the current active plan step under validation.

Be concise.

B. Test Follow-Up / Test Implementation

When to use

Use only after TEST mode A identifies the exact tests to add or update.

Inputs

• feature slug
• docs/plans/<feature_slug>_plan.md
• TEST mode A output
• existing test files and patterns
• relevant implementation files

Output

• new or updated tests only
• modified test file paths
• coverage notes
• blockers or follow-ups
• confirmation that no unrelated feature logic was changed

EXECUTE (TEST FOLLOW-UP)

Use only after TEST mode A identifies the tests that should be added or updated.

Task Implement ONLY the missing or failing tests identified in TEST mode A.

Fail-safe (CRITICAL):

• Before proceeding, scan docs/plans/<feature_slug>_plan.md
• Identify the FIRST unchecked step (- [ ])
• If no unchecked step exists → STOP: "No active step found. Testing phase is complete."

Context

• Feature: <feature_slug>
• Plan file: docs/plans/<feature_slug>_plan.md

Current step detection (REQUIRED):

• Read docs/plans/<feature_slug>_plan.md
• Identify the FIRST unchecked step (- [ ])
• This is the step under test
• Do NOT rely on manual input

Before writing tests

• read docs/plans/<feature_slug>_plan.md and detect current step
• review implementation from last EXECUTE
• review TEST mode A output
• review existing test structure
• do not modify plan state

Tests to implement <paste tests from TEST mode A here>

Stop Conditions

• All identified tests implemented
• OR feature logic must change → STOP
• OR test expectations unclear → STOP

Rules

• Only implement or update tests
• Do NOT modify feature logic unless required to make code testable
• If feature logic must change → STOP and report it
• Follow existing test patterns and structure
• Place tests in correct existing files
• Do NOT introduce new frameworks
• Keep changes minimal
• Do NOT fix unrelated failing tests
• Do NOT expand beyond current active plan step under validation
• do NOT invent tests beyond TEST mode A scope
• prefer existing test utilities and helpers

Output Format

1. Tests added or updated
2. Files changed
3. Test coverage notes
4. Blockers / follow-ups

Completion confirmation:

• Confirm only tests were changed
• Confirm no unrelated feature logic was modified

Goal: Add the smallest correct set of tests needed to validate the current plan step.
