Example for using pyproject.toml for setting env vars

Thanks @nermand and @bosatsu! Good pointers. I can confirm that any of the below work without python-dotenv or pytest-dotenv: 1.

[tool.pytest.ini_options]
env = [
 "HOME=~/tmp",
 "RUN_ENV=test"
]

[tool.pytest.ini_options]
env ="HOME=~/tmp\nRUN_ENV=test"

[tool.pytest.ini_options]
env = """
    HOME=~/tmp
    RUN_ENV=test
"""

If it doesn’t recommend rechecking the pytest version. My pytest version was downgraded to <6.0, without me noticing, and since pyproject.toml support was added in 6.0+, it wasn’t working.

The following works for me, and I’m not using python-dotenv:

[tool.pytest.ini_options]
env = '''
    HOME=~/tmp
    RUN_ENV=test
'''
