codspeed-trial

Test repository for evaluating CodSpeed continuous benchmarking service.

Overview

This package includes:

• C++ extension: NumPy-interfaced module for computing sum of squares
• Cython extension: Optimized Fibonacci number computation
• CodSpeed benchmarks: Performance tests using pytest-codspeed
• Overhead tests: Identical tests without benchmarking for comparison

Setup

Install dependencies with pixi:

pixi install

Build the package:

pixi run build

Running Tests

Run CodSpeed benchmarks:

pixi run benchmark

Run overhead comparison tests:

pixi run test-overhead

Run all tests:

pixi run test

CI/CD

The GitHub Actions workflow (.github/workflows/codspeed.yml) automatically:

• Builds the package on ubuntu-latest runners
• Runs benchmarks with CodSpeed on pushes and PRs
• Uses OIDC authentication for secure integration with CodSpeed
