spec-test 0.1.4

Specification-driven development tool with test verification

spec-test

Specification-driven development tool that verifies your specs have passing tests.

Philosophy

Every claim about system behavior must be backed by a passing test.

• If there's no test, the behavior is unverified
• Specs are written first, then implementation, then tests
• spec-test verify is the source of truth for project health

Installation

pip install spec-test
# or with uv
uv add spec-test

Quick Start

1. Create a spec file anywhere in your project (must be spec-*.md):

# docs/specs/spec-auth.md

## Requirements
- **AUTH-001**: User can login with email and password
- **AUTH-002**: Invalid credentials return 401 error

2. Write tests with the @spec decorator:

from spec_test import spec

@spec("AUTH-001", "User can login with email and password")
def test_user_login():
    response = client.post("/login", json={"email": "[e-mail]", "password": "secret"})
    assert response.status_code == 200

@spec("AUTH-002", "Invalid credentials return 401 error")
def test_invalid_login():
    response = client.post("/login", json={"email": "[e-mail]", "password": "wrong"})
    assert response.status_code == 401

3. Verify all specs have passing tests:

spec-test verify

Commands

spec-test verify          # Verify all specs have passing tests
spec-test list-specs      # List all specs found
spec-test check AUTH-001  # Check a single spec
spec-test init            # Initialize spec-test in a project

Spec File Format

Spec files must:

• Be named spec-*.md (e.g., spec-auth.md, spec-api.md)
• Can be anywhere in the project (nested directories supported)
• Use **ID**: description format for requirements

- **AUTH-001**: User can login with email and password
- **AUTH-002** [manual]: Requires manual verification
