Package: pytest-virtualenv
Create a Python virtual environment in your test that cleans up on
teardown. The fixture has utility methods to install packages and list
what’s installed.InstallationInstall using your favourite package installer:pipinstallpytest-virtualenv# oreasy_installpytest-virtualenvEnable the fixture explicitly in your tests or conftest.py (not required
when using setuptools entry points):pytest_plugins=['pytest_virtualenv']ConfigurationThis fixture is configured using the following evironment variablesSettingDescriptionDefaultVIRTUALENV_FIXTURE_EXECUTABLEWhich virtualenv executable will be used to create new venvsvirtualenvFixture AttributesHere’s a noddy test case to demonstrate the basic fixture attributes.
For more information onpath.pyseehttps://pathpy.readthedocs.io/deftest_virtualenv(virtualenv):# the 'virtualenv' attribute is a `path.py` object for the root of the virtualenvdirnames=virtualenv.virtualenv.dirs()assert{'bin','include','lib'}.intersection(set(dirnames))# the 'python' attribute is a `path.py` object for the python executableassertvirtualenv.python.endswith('/bin/python')Installing PackagesYou can install packages by name and query what’s installed.deftest_installing(virtualenv):virtualenv.install_package('coverage',installer='pip')# installed_packages() will return a list of `PackageEntry` objects.assert'coverage'in[i.nameforiinvirtualenv.installed_packages()]Developing Source CheckoutsAny packages set up in thetest runner’spython environment (ie, the
same runtime thatpy.testis installed in) as source checkouts usingpython setup.py developwill be detected as such and can be
installed by name usinginstall_package. By default they are
installed into the virtualenv usingpython setup.py develop, there
is an option to build and install an egg as well:deftest_installing_source(virtualenv):# Install a source checkout of my_package as an egg filevirtualenv.install_package('my_package',build_egg=True)Running CommandsThe test fixture has arunmethod which allows you to run commands
with the correct paths set up as if you had activated the virtualenv
first.deftest_run(virtualenv):python_exe_path=virtualenv.pythonruntime_exe=virtualenv.run("python -c 'import sys; print sys.executable'",capture=True)assertruntime_exe==python_exe_pathRunning Commands With CoverageThe test fixture has arun_with_coveragemethod which is likerunbut runs the command under coverageinside the virtualenv.
This is useful for capturing test coverage on tools that are being
tested outside the normal test runner environment.deftest_coverage(virtualenv):# You will have to install coverage firstvirtualenv.install_package(coverage)virtualenv.run_with_coverage(["my_entry_point","--arg1","--arg2"])Changelog1.7.0All: Support pytest >= 4.0.0All: Support Python 3.7pytest-server-fixtures: if host not defined on your machine, default
