kiwitcms-requirements 0.2.2

Requirements management and traceability plugin for Kiwi TCMS: registry of requirements, M2M trace to test cases, Sankey traceability, coverage dashboard with charts, JIRA-ready CSV export, XLSX/DOCX/PDF reports, ASPICE / ISO 9001 support.

kiwitcms-requirements

Requirements management and traceability plugin for Kiwi TCMS.

A first-class registry of requirements mapped many-to-many to test cases, with a Sankey traceability diagram, coverage dashboard, document-control fields, CSV / XLSX / DOCX / PDF / JIRA-native exports, and configurable level profiles for ASPICE, ISO 9001, IEC 62304, DO-178C, or plain generic use.

Why

Kiwi TCMS ships with a single TestCase.requirement CharField (max 255 characters). That's a label, not traceability. Teams working to quality or safety standards need:

• A first-class Requirement entity with identity, source, level, and status
• Many-to-many links to test cases with typed relationships (verifies / validates / derives-from / related)
• Coverage analytics — what's tested, what isn't, and by how much
• Document-control fields (doc ID, revision, effective date, supersession chain) for ISO 9001 §7.5
• JIRA-ready CSV export so requirements can be pushed into downstream ALM tools
• Full audit trail of every change via django-simple-history

This plugin adds that layer alongside the existing TestCase.requirement CharField (which is left untouched for backward-compat).

Features (v0.2.0)

Registry, list & detail

Filterable list with status / priority / level / category / source / project / feature filters, pill-style status and priority badges, JIRA issue keys, link counts.

Per-requirement detail page with description, rationale, linked test cases (with link-type icons + suspect badges), child requirements, full activity history, and a PatternFly metadata sidebar.

Sankey traceability diagram

Requirement → Test case → Test plan, filterable by product / project / feature, colour-coded by node kind, with suspect links shown in red. Export to DOCX or PDF embeds the live-rendered SVG on page 1 followed by a full row-by-row traceability table on page 2+.

Coverage dashboard

Coverage %, orphan requirements, suspect links, plus donuts and bars for status / priority / level / category breakdown. ASIL / DAL / IEC 62304 safety-distribution chart shown only when at least one requirement has safety classification.

Export the dashboard snapshot to DOCX or PDF directly from the page header.

Authoring

Fieldset-grouped form organised by concern: identity, taxonomy, organisation, lifecycle, and collapsible sections for safety/criticality classifications, ISO 9001 document control, and external system keys.

Test case linking

Dedicated picker with JSON-RPC-driven search that calls Kiwi's TestCase.filter; manual TC-id fallback when the JSON-RPC helper isn't available on the page.

Import — CSV or XLSX with dry-run

Dry-run preview validates FK references, reports per-row errors, then commits with a re-submit. Download ready-to-use XLSX or CSV templates with headers + three sample rows.

Export — JIRA, CSV, JSON, DOCX, PDF

The JIRA-import CSV uses JIRA-native column names so a direct import via System → External System Import → CSV works with no manual field mapping. Operator overrides via REQUIREMENTS_JIRA_EXPORT_MAPPING for issue type, status, priority, and custom-field IDs.

Safety / traceability affordances

• Suspect-link flagging on requirement text change (automatic; cleared by reviewer)
• Supersession chain (Requirement.superseded_by) for ISO 9001 §7.5 controlled documents
• Change-reason enforcement on status → deprecated / superseded
• Configurable level profile (REQUIREMENTS_LEVEL_PROFILE): aspice / iso9001 / iec62304 / do178c / generic
• Full django-simple-history audit trail on every mutating model
• Safety/criticality fields: ASIL (ISO 26262), SIL (IEC 61508), DAL (DO-178C), IEC 62304 Class

Install

pip install kiwitcms-requirements

The package exposes a kiwitcms.plugins entry point; Kiwi discovers it automatically on next start.

./manage.py migrate tcms_requirements
./manage.py collectstatic

That's it. The plugin registers its menu entries, admin tabs, and middleware in apps.py::ready() — no manual INSTALLED_APPS or MIDDLEWARE editing required.

Level profiles

The RequirementLevel table is configurable. The seed migration applies a profile based on your REQUIREMENTS_LEVEL_PROFILE setting (default: aspice):

Profile	Default levels
aspice (default)	stakeholder → system → software → component → unit
iso9001	customer_requirement → product_requirement → process_requirement → quality_objective
iec62304	user_need → software_req → arch_req → detailed_design → unit
do178c	high_level → low_level → source_code
generic	requirement (single level, no decomposition enforced)

Add to tcms_settings_dir/requirements.py:

REQUIREMENTS_LEVEL_PROFILE = "iso9001"

…and rerun ./manage.py migrate. The seed migration is idempotent — existing requirements keep their FK regardless of profile changes; the operator can edit, add, or deactivate level rows from the Django admin at any time.

Standards support

Standard	What the plugin provides
ASPICE / ISO 26262	Level profile maps to SYS.2 / SYS.5 / SWE.1 / SWE.6 / SUP.10 / MAN.5 / SUP.8. ASIL classification per requirement. Bidirectional trace from requirements to TestCase + TestExecution.
ISO 9001 / ISO 13485	Document-control fields (doc_id, doc_revision, effective_date, superseded_by), change-reason enforcement, approval/verification gates, auditable supersession chain.
IEC 62304	iec62304_class (A/B/C) per requirement, level profile for user need → software → architecture → detailed design → unit.
DO-178C	dal (A–E) per requirement, level profile for high-level → low-level → source code.
No formal standard	generic level profile; registry, M2M, exports all still work.

Exporting to JIRA

The JIRA-import CSV export lands at:

/requirements/export/jira-csv/

Append filter query-params (?product=1&status=approved) to scope the export. The resulting file imports directly via JIRA's System → External System Import → CSV with no manual field mapping.

Column mapping is overridable via REQUIREMENTS_JIRA_EXPORT_MAPPING:

REQUIREMENTS_JIRA_EXPORT_MAPPING = {
    "issue_type": "Requirement",    # if your JIRA has a Requirement issue type
    "priority": {"critical": "Blocker", "high": "Critical"},
    "status": {"approved": "Approved"},
    "custom_fields": {
        "level": "customfield_10045",          # direct custom-field ID
        "parent_requirement": "Parent Link",
    },
}

The mapping merges over the defaults — only declare what you want to change. Issue Key is populated on re-export after the first round-trip, so JIRA-assigned keys round-trip cleanly back into Requirement.jira_issue_key.

Demo data

Seeds 12 demo requirements across 3 features with a stakeholder → system → software decomposition chain and mixed link types so the Sankey and dashboard have something to show:

./manage.py seed_demo_requirements

Flags:

• --product "Infotainment ECU" — scope under a specific product (defaults to first)
• --cases 8 — number of TestCases to link (default 8)
• --flush — delete previous DEMO-* rows before re-seeding

Permissions

Seeded on post_migrate and granted to the Tester / Administrator groups:

• requirements.view_requirement / add_ / change_ / delete_
• requirements.add_requirementtestcaselink / change_ / delete_
• (future v0.3+) requirements.approve_requirement — gates approved/verified status

Dependencies

Runtime (installed automatically):

• Django 4.2 / 5.0 / 5.2
• django-simple-history
• django-modern-rpc
• markdown, requests
• openpyxl (XLSX import/templates)
• python-docx (DOCX reports)
• reportlab (PDF reports)
• svglib, Pillow (Sankey → DOCX/PDF image embedding)

Running the test suite

cd tcms_requirements
PYTHONPATH=.. DJANGO_SETTINGS_MODULE=tcms_requirements.tests.settings \
    python -m unittest discover tests

The unit tests don't require a live Kiwi install — they exercise state_machine and exports/jira_csv_export in isolation.

Compatibility

• Python 3.9 +
• Django 4.2 / 5.0 / 5.2
• Kiwi TCMS (current stable release)
