How can I use pytest-benchmark fixtures in my tests?

You can use the benchmark fixture provided by the pytest-benchmark plugin to measure the performance of your code.

Can you show me a simple example of using the benchmark fixture?

Sure! Here's a basic example:

import pytest

def my_function():
    # some code to benchmark
    return sum(range(1000))

def test_my_function(benchmark):
    result = benchmark(my_function)
    assert result == 499500

What if I want to compare two different functions?

You can use the benchmark fixture to run both functions and compare their results like this:

def my_function_1():
    return sum(range(1000))

def my_function_2():
    return sum(range(2000))

def test_compare_functions(benchmark):
    result_1 = benchmark(my_function_1)
    result_2 = benchmark(my_function_2)
    assert result_1 < result_2
