Test Suites

Build Status

Performance tests divided into suites.

Prerequisites

Install and run

$ cd testsuite
$ pip install -r ./requirements.txt
$ ./run.py test_suite [test_suite ...]

test_suite is one of available test suites:

load, convert, composition, rotate_right, scale,
blur, wand_load, wand_convert, wand_composition,
wand_rotate_right, wand_scale, wand_blur, cv2_load,
cv2_rotate_right, cv2_scale, cv2_blur

The list can grow, please refer to:

$ ./run.py --help

CLI

$ ./run.py scale --progress
$ ./run.py scale --mode RGBA
$ ./run.py scale --runs 50
$ ./run.py scale --size 512x512

For some suites the chosen mode (scale, blur) does matter, while others (convert, composition) work regardless of current mode.

Automatic test

Automatic test launches test suites against relevant Pillow versions including SSE4 and AVX2. Currently it only works on Linux Ubuntu.

You have two ways to run the test: Vagrant or host (tested on Ubuntu 14.04 and 16.04).

Run in Vagrant

Please, ensure that you are using Vagrant version 1.8.7 or later.

$ cd auto
$ vagrant up

It will automatically start a full test which can take over 10 minutes. Run the test again:

$ vagrant provision --provision-with run

Run on the host

First you need to install the prerequisites:

$ cd auto
$ sudo ./install_ubuntu.sh

Script options:

$ cd auto
$ ./run.sh                # Run all tests
$ ./run.sh no             # Skip AVX2 tests
$ ./run.sh - --json       # Pass extra arguments to test suite
$ ./run.sh no --json      # Pass extra arguments and skip AVX2 tests
$ CC="ccache cc" ./run.sh # Speed up subsequent builds using CC cache

Submit results

We are concerned in tests on a AMD CPU with AVX2 (Zen microarchitecture) and on an Intel Skylake CPU.

  1. Before running any tests, please ensure that you have exited all browsers on the host machine, closed all audio players and stopped any backup systems. The full test lasts up to 15 minutes.

  2. Run automatic test with --json option. Please avoid custom --size, --mode and --runs settings.

    $ ./run.sh - --json
  3. Collect the following information about your system: name, OS version, CPU. For example:

    • Name: MacBook Pro (Retina, 13-inch, Late 2013)
    • OS: Ubuntu 14.04.4 LTS 64bit
    • CPU: Intel® Core™ i5-4258U CPU @ 2.40GHz
  4. Create an issue with the collected information and test output.
