Pytest running doesn't take into consideration env.

Environment data

• VS Code version: 1.36.1
• Extension version (available under the Extensions sidebar): 2019.9.29489-dev
• OS and version: Ubuntu 19.04
• Python version (& distribution if applicable, e.g. Anaconda): 2.7.15+
• Type of virtual environment used (N/A | venv | virtualenv | conda | …): virtualenv
• Relevant/affected Python packages and their versions: pytest
• Jedi or Language Server? (i.e. what is "python.jediEnabled" set to; more info #3977): LanguageServer

Expected behaviour

Test discovery and running have the enviroment variables declared in the .env file or the terminal.integrated.env.linux settings before executing.

Actual behaviour

Tests that depend on a specific environment variable being set to run fail.

Steps to reproduce:

1. Set a test that depends on a enviroment variable to run.
2. Declare that variable in an .env file or in terminal.integrated.env.linux
3. Run test.

Logs

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)

In this output I’m running a test that depends on a variable PANOPTA_INTEGRATION_TESTS_CONFIG to point to a file, and if not found it defaults to this file /etc/panopta_tests_support_data.yaml, which doesn’t exist. I have declared said variable in an .env file at my workspace root. PANOPTA_INTEGRATION_TESTS_CONFIG=/home/cllamach/Panopta/classic/src/models/tests/integration/support_data_config.yaml

But when adding log statements to pytest run module I see it tries to load the default file instead of the one declared in the .env file. I ran into a similar problem with the PYTHONPATH variable not being taken into account when declared into the .env file and was able to bypass it by installing pytest-pythonpath to declare its values there.

@nickcointracker yes, it does when you specify the path to the .env file in your settings.json file. For example, if the .env file is in your workspace folder, you can add the following line there:

"python.envFile": "${workspaceFolder}/.env"

Does that help you?

@CMLL the way i solved it was to install pytest-dotenv

I ran the command pip install pytest-dotenv

And ready! Maybe you need to reload the vscode application
