pyforge-test 0.3.0

A lightweight Python unit testing framework with decorator-based test collection and execution.

PyForge Testing Framework

A lightweight Python testing framework with decorator-based test collection and automatic discovery—designed for personal projects and learning.

Note: PyForge is designed for personal projects, learning, and small-scale testing. It is not a substitute for production frameworks like pytest.

Features

• 🎯 Simple Decorators — Mark tests with @test, automatic collection
• 🚀 Zero Configuration — Works out of the box
• 📦 Zero Dependencies — Pure Python, nothing to install but PyForge itself
• 🔍 Auto-Discovery — Finds and loads all test*.py files automatically
• ⚡ Fast Execution — Minimal overhead, quick feedback
• 🏷️ Test Markers — Organize tests by priority (integration, slow)
• 📊 Parameterized Tests — Run one test with multiple inputs
• ⊘ Skip Tests — Conditionally skip tests with clear reasons
• ✅ Full Type Hints — PEP 484 type annotations throughout
• 🎨 Clean Output — Color-coded results with minimal internal noise

Installation

pip install pyforge-test

Or from GitHub:

pip install git+https://github.com/ertanturk/pyforge-test.git

Quick Start

1. Create Test File

mkdir -p tests && touch tests/__init__.py

Create tests/test_example.py:

from pyforge_test import test


@test
def test_addition() -> None:
    """Test basic arithmetic."""
    assert 2 + 2 == 4


@test
def test_strings() -> None:
    """Test string manipulation."""
    assert "hello".upper() == "HELLO"

2. Run Tests

pyforge

Expected output:

Discovering test modules in '/path/to/tests'...
Loaded: test_example.py

Loaded 1 test module(s).

Executing 2 test(s).

PyForge Test Results
------------------------------------------------------------------------

test_example.py
  PASSED test_addition (Line 4)

------------------------------------------------------------------------
Summary: PASSED: 2/2  FAILED: 0/2  SKIPPED: 0/2  ERRORS: 0/2
Took 5 ms to execute all tests

CLI Options

pyforge              # Run all tests
pyforge -q           # Quiet: only failures
pyforge -v           # Verbose: full tracebacks
pyforge --fail-fast  # Stop on first failure
pyforge -k api       # Filter by test name
pyforge test_api.py  # Run specific file

Test Features

Basic Tests

from pyforge_test import test


@test
def test_example() -> None:
    """Test function requirements:
    - Starts with 'test_'
    - No parameters
    - Return type -> None
    - Uses @test decorator
    """
    assert True

Parameterized Tests

Run the same test with multiple inputs:

from pyforge_test import test_parameterized


@test_parameterized([
    (2, 3, 5),
    (10, 5, 15),
    (100, 200, 300),
])
def test_addition(a: int, b: int, expected: int) -> None:
    """Generates: test_addition_0, test_addition_1, test_addition_2"""
    assert a + b == expected

Test Markers

Execution priority: Unmarked (0) → Integration (1) → Slow (2)

from pyforge_test import test, test_marker

# Fast unit test (runs first)
@test
def test_fast() -> None:
    assert 2 + 2 == 4

# Integration test (requires external resources)
@test_marker("integration")
@test
def test_database() -> None:
    db.connect()
    assert db.is_connected()

# Slow test (performance-intensive)
@test_marker("slow")
@test
def test_large_dataset() -> None:
    result = process_records(1_000_000)
    assert len(result) == 1_000_000

Important: @test_marker must come before @test

Skip Tests

import sys
from pyforge_test import test, test_skip, test_skipif


@test_skip(reason="Not implemented yet")
def test_future() -> None:
    """Always skipped."""
    pass


@test_skipif(sys.platform == "win32", reason="Unix only")
def test_unix() -> None:
    """Skipped on Windows."""
    pass
