Step 3: Blackbox Test Task Decomposition (tests-only mode only)

Role: Professional Quality Assurance Engineer Goal: Decompose blackbox test specs into atomic, implementable task specs. Constraints: Behavioral specs only — describe what, not how. No test code.

Numbering

• In tests-only mode: start from 02 (01 is the test infrastructure bootstrap from Step 1t).

Steps

1. Read all test specs from DOCUMENT_DIR/tests/ (blackbox-tests.md, performance-tests.md, resilience-tests.md, security-tests.md, resource-limit-tests.md)
2. Group related test scenarios into atomic tasks (e.g., one task per test category or per component under test)
3. Each task should reference the specific test scenarios it implements and the environment/test-data specs
4. Dependencies:
   • In tests-only mode: blackbox test tasks depend on the test infrastructure bootstrap task (Step 1t)
5. Write each task spec using templates/task.md
6. Estimate complexity per task (1, 2, 3, 5 points); no task should exceed 5 points — split if it does
7. Note task dependencies (referencing tracker IDs of already-created dependency tasks)
8. Immediately after writing each task file: create a work item ticket under the "Blackbox Tests" epic, write the work item ticket ID and Epic ID back into the task header, then rename the file from todo/[##]_[short_name].md to todo/[TRACKER-ID]_[short_name].md.

Self-verification

• Every scenario from tests/blackbox-tests.md is covered by a task
• Every scenario from tests/performance-tests.md, tests/resilience-tests.md, tests/security-tests.md, and tests/resource-limit-tests.md is covered by a task
• No task exceeds 5 complexity points
• Dependencies correctly reference the test infrastructure task
• Every task has a work item ticket linked to the "Blackbox Tests" epic

Save action

Write each todo/[##]_[short_name].md (temporary numeric name), create work item ticket inline, then rename to todo/[TRACKER-ID]_[short_name].md.
