How can I compare benchmarks using pytest-benchmark?

What is pytest-benchmark and how can I use it to compare benchmarks?

pytest-benchmark is a plugin for pytest that allows you to measure and compare the performance of your code. You can use it to run benchmarks and analyze the results.

Can you show me an example of how to compare two benchmarks?

Sure! You can use the --benchmark-compare option to compare benchmarks. First, run your benchmarks, then use that option to see the comparison.

What kind of output can I expect from the comparison?

The output will show you the performance differences between the benchmarks, including metrics like mean time and standard deviation.

Are there any specific configurations I need to set up for accurate comparisons?

Yes, ensure that your benchmarks are isolated and run under similar conditions to get accurate comparisons. You can also configure the number of iterations.
