Installation

You can install “pytest-performance” via pip from PyPI:

$ pip install pytest-performance

Usage

• Default

def my_func(*args, **kwargs):
    return 123

def test_my_func(performance):
    # Check my_func runs within 1 second for 10000 iterations.
    result = performance(my_func)
    assert result == 123

• Set custom time amount

def my_func(*args, **kwargs):
    return 123

def test_my_func(performance):
    # Check my_func runs within 10 seconds for 10000 iterations.
    result = performance(my_func, target=10)
    assert result == 123

• Set custom time amount and unit (pint units supported)

def my_func(*args, **kwargs):
    return 123

def test_my_func(performance):
    # Check my_func runs within 1 nanosecond for 10000 iterations.
    result = performance(my_func, target=10, unit='ns')
    assert result == 123

• Set custom time amount, unit and number of iterations

def my_func(*args, **kwargs):
    return 123

def test_my_func(performance):
    # Check my_func runs within 1 nanosecond for 10 iterations.
    result = performance(my_func, target=10, unit='ns', iterations=10)
    assert result == 123

• Fixture can be disabled by passing ‘–performance-skip’ to pytest
