pytest-monitor 1.6.6

Features

• Analyze your resources consumption through test functions:

  • memory consumption

  • time duration

  • CPU usage

• Keep a history of your resource consumption measurements.

• Compare how your code behaves between different environments.

Usage

Simply run pytest as usual: pytest-monitor is active by default as soon as it is installed. After running your first session, a .pymon sqlite database will be accessible in the directory where pytest was run.

Example of information collected for the execution context:

Here is an example of collected data stored in the result database:

Documentation

A full documentation is available.

Installation

You can install pytest-monitor via conda (through the conda-forge channel):

$ conda install pytest-monitor -c https://conda.anaconda.org/conda-forge

Another possibility is to install pytest-monitor via pip from PyPI:

$ pip install pytest-monitor

Requirements

You will need a valid Python 3.5+ interpreter. To get measures, we rely on:

• psutil to extract CPU usage

• memory_profiler to collect memory usage

• and pytest (obviously!)

Note: this plugin doesn’t work with unittest

Storage backends

By default, pytest-monitor stores its result in a local SQLite3 local database, making results accessible. If you need a more powerful way to analyze your results, checkout the monitor-server-api which brings both a REST Api for storing and historize your results and an API to query your data. An alternative service (using MongoDB) can be used thanks to a contribution from @dremdem: pytest-monitor-backend.
