pytest-benchmark is a plugin for the pytest testing framework that enables developers to measure and track the performance of their code. It provides a fixture to benchmark functions, offering features like automatic calibration, comparison and regression tracking, and detailed statistics. This tool is particularly useful for identifying performance bottlenecks and ensuring that code changes do not degrade performance.

Usage Example​

Here’s an example of how to use pytest-benchmark to benchmark a function:

import time

def my_function():
    time.sleep(0.1)

def test_my_function(benchmark):
    benchmark(my_function)

In this example:

  • my_function is a simple function that sleeps for 0.1 seconds.
  • The test_my_function function uses the benchmark fixture provided by pytest-benchmark to measure the performance of my_function.

To run the benchmark, execute:

pytest test_my_function.py

This will output performance metrics for my_function, helping you assess its efficiency.
