How can tox install the modules via the requirements file?
PythonToxPython Problem Overview
Our python project has a requirements.txt file which lists some dependent module. We used to use
pip install -r requirements.txt
to install these dependencies. We are now using tox to build up the test environment. My question is that how can we install the modules via requirements.txt directly.
Followings are our tox.ini and requirements.txt:
tox.ini:
[tox]
envlist=py27
[testenv]
deps=pytest
boto
commands=py.test
rquirements.txt:
boto
Is any way to remove the "boto" from tox.ini and add something like
deps_files=requirements.txt
Python Solutions
Solution 1 - Python
deps = -r{toxinidir}/tools/pip-requires
-r{toxinidir}/tools/test-requires
Solution 2 - Python
What helped me is the following (the other solution didn't work for me):
deps=
pytest
-rrequirements.txt
This works at least if you add requirements.txt to MANIFEST.in and if you use a relatively new `tox (>= 1.6.1) version (see here).
Solution 3 - Python
I had already setup my dependencies as in the accepted answer above, however any new dependencies were not installed like they are when tox is run for the first time. To install new dependencies in the virtualenv I had to force tox to recreate the environment like so:
tox --recreate -e py27
[UPDATE: this issue should be fixed in tox v4]
Solution 4 - Python
You can put dependencies and test dependencies in requirements.txt and requirements.testing.txt in order to the root directory.
Put tox.ini in your root directory of your project and you can use the approach below to install dependencies.
[testenv] deps = -r{toxinidir}/requirements.txt -r{toxinidir}/requirements.testing.txt
In addition to upgrade dependencies
[testenv] deps = -Ur{toxinidir}/requirements.txt -Ur{toxinidir}/requirements.testing.txt
