Description:

pytestcodspeed 2.2.1

pytest-codspeed

Pytest plugin to create CodSpeed benchmarks

Requirements
Python: 3.7 and later
pytest: any recent version
Installation
pip install pytest-codspeed

Usage
Creating benchmarks
Creating benchmarks with pytest-codspeed is compatible with the standard pytest-benchmark API. So if you already have benchmarks written with it, you can start using pytest-codspeed right away.
Marking a whole test function as a benchmark with pytest.mark.benchmark
import pytest
from statistics import median

@pytest.mark.benchmark
def test_median_performance():
return median([1, 2, 3, 4, 5])

Benchmarking selected lines of a test function with the benchmark fixture
import pytest
from statistics import mean

def test_mean_performance(benchmark):
# Precompute some data useful for the benchmark but that should not be
# included in the benchmark time
data = [1, 2, 3, 4, 5]

# Benchmark the execution of the function
benchmark(lambda: mean(data))

def test_mean_and_median_performance(benchmark):
# Precompute some data useful for the benchmark but that should not be
# included in the benchmark time
data = [1, 2, 3, 4, 5]

# Benchmark the execution of the function:
# The `@benchmark` decorator will automatically call the function and
# measure its execution
@benchmark
def bench():
mean(data)
median(data)

Running benchmarks
Testing the benchmarks locally
If you want to run only the benchmarks tests locally, you can use the --codspeed pytest flag:
pytest tests/ --codspeed

Note: Running pytest-codspeed locally will not produce any performance reporting. It's only useful for making sure that your benchmarks are working as expected. If you want to get performance reporting, you should run the benchmarks in your CI.

In your CI
You can use the CodSpeedHQ/action to run the benchmarks in Github Actions and upload the results to CodSpeed.
