Command line utility for using the Pytest testing framework in 3ds Max
Project description
Overview
Command line tool for a friendly testing workflow using the Pytest framework in 3ds Max
- Run tests with all 3ds Max Python APIs, including GUI/PySide2 libraries
- Source dependencies from a pipenv virtual environment
- Automate a new 3ds Max/python session for each tests invocation
Setup
Install with pip
Install with pip using Python 2.7:
pip install maxpytest
Setup pipenv
When run from a project root, modules installed to the project's associated pipenv virtual environment. To use a virtual environment associated with another directory (where Pipfile/Pipfile.lock are located) override the current working dir with maxpytest --cwd
.
If you already have a pipenv virtual environment for your project, make sure it has pytest installed.
To install pipenv, run from your project root:
pip install pipenv
Then, setup a pipenv virtual environment:
pipenv --python 2.7 install
Add pytest to the virtual environment:
pipenv install pytest
Usage
Due to the caching mechanism of python's import system and Pytest's design, changes made to test files (and any modules they import) will not be reflected in subsequent Pytest invocations in the same python process. This means ensuring that your changes are reflected requires a restart of the 3ds Max/python session.
The argument -m/--max
directs maxpytest
how to run your tests. For maxpytest to handle closing and relaunching 3ds Max automatically, run your tests using MXSPyCOM. For a simple setup, or if targeting multiple 3ds Max versions, run your tests directly with 3ds Max. To use the first discovered method, run your tests using the default run method.
Run your tests using MXSPyCOM
When you run your tests with MXSPyCOM, the closing and relaunching 3ds Max is handled automatically. Any unsaved work will trigger a prompt to save it before closing. For more about MXSPyCOM see the wiki.
To invoke your tests, use maxpytest -m [path to MXSPyCOM.exe] -py [pytest args]
, with Pytest args following -py
or --pytest
as the final command argument.
For example:
# Relaunch 3ds Max then invoke pytest from current working dir with verbose
maxpytest -m "C:\\Program Files\\MXSPyCOM\\MXSPyCOM.exe" -py -v .
# Relaunch 3ds Max then invoke pytest in directory ./tests
maxpytest -m "C:\\Program Files\\MXSPyCOM\\MXSPyCOM.exe" -py tests/
# Skip relaunch and just invoke pytest in directory ./tests
maxpytest -m "C:\\Program Files\\MXSPyCOM\\MXSPyCOM.exe" --no-restart -py tests/
Test results print to the 3ds Max Listener.
Run your tests directly with 3ds Max
To run tests in 3ds max without using MXSPyCOM, use -m/--max
with the version year of the 3ds Max you wish to target, or a full path to 3dsmax.exe.
For example:
# Invoke pytest from current working dir in a new instance of 3ds Max 2019
maxpytest -m "C:\\Program Files\\Autodesk\\3ds Max 2019\\3dsmax.exe"
# Invoke pytest from current working dir in a new instance of 3ds Max 2019
maxpytest -m 2019
# Invoke pytest from current working dir and run tests in ./tests
maxpytest -m 2016 -py tests/ -v
Test results will print to the 3ds Max Listener.
Run your tests using the default run method
If maxtest
is used without a -m/--max
argument, maxpytest will search for MXSPyCOM.exe at C:\Program Files\MXSPyCOM\MXSPyCOM.exe
. If not found, the most recent version of 3ds Max installed on the system will be used.
