pytest-reqcov 0.2.0

A pytest plugin for requirement coverage tracking

pytest-reqcov

A pytest plugin for requirement coverage tracking.

Features

• Track test coverage against requirements and products
• Integrate with pytest workflow

Installation

Install from PyPI:

pip install pytest-reqcov

Usage

Add requirement markers to your tests:

import pytest

@pytest.mark.req(id="REQ-001")
def test_user_login():
    """Test user login functionality."""
    assert login_user("user", "password") == True

@pytest.mark.product(id="ProductA")
def test_user_logout():
    """Test user logout functionality."""
    assert logout_user() == True

Run pytest with requirement coverage:

pytest --reqcov-reqs=requirements.csv --reqcov-prods=products.csv  --reqcov-output=output.csv

Merging Multiple Coverage Reports

When running tests across multiple test suites or environments, you can merge the generated coverage reports using the reqcov-merge command:

# Merge multiple output files
reqcov-merge output1.csv output2.csv output3.csv -o merged_output.csv

# Merge with verbose output
reqcov-merge output1.csv output2.csv -o merged_output.csv --verbose

The merge script applies the AND operator for status determination:

• If all tests for a requirement/product are PASSED, the merged status is PASSED
• If any test for a requirement/product is FAILED, the merged status is FAILED
• Tests from multiple files are combined into a comma-separated list

Example merge scenario:

# output1.csv
item;type;status;tests
REQ001;requirement;PASSED;test_req_1
Product_A;product;PASSED;test_product_a1

# output2.csv
item;type;status;tests
REQ001;requirement;FAILED;test_req_2
Product_A;product;PASSED;test_product_a2

# merged_output.csv (result)
item;type;status;tests
REQ001;requirement;FAILED;test_req_1,test_req_2
Product_A;product;PASSED;test_product_a1,test_product_a2

Configuration

Add configuration to your pytest.ini or pyproject.toml:

[tool.pytest.ini_options]
markers = [
    "req: tests with associated requirements",
    "product: tests with associated product",
]
