How can I visualize benchmark results from pytest?

You can use the pytest-benchmark plugin to generate benchmark results and then visualize them using tools like Matplotlib or Pandas.

What format does pytest-benchmark output the results in?

It outputs results in a JSON format by default, which you can then use for further analysis or visualization.

Can you show me an example of how to plot these results?

Sure! After running your benchmarks, you can load the JSON file and use Matplotlib to create a plot. Would you like a code snippet?

Yes, please provide a code snippet for that!

Here's a simple example:

import json
import matplotlib.pyplot as plt

with open('benchmark.json') as f:
    data = json.load(f)

# Extracting data for plotting
names = [item['name'] for item in data['benchmarks']]
values = [item['stats']['mean'] for item in data['benchmarks']]

plt.bar(names, values)
plt.ylabel('Time (seconds)')
plt.title('Benchmark Results')
plt.show()
