This is a `pytest` plugin that enables you to set environment variables in a `pytest.ini` or `pyproject.toml` file.
## Installation
Install with pip:
```shell
pip install pytest-env
```
## Usage
### Native form in `pyproject.toml`
```toml
[tool.pytest_env]
HOME = "~/tmp"
RUN_ENV = 1
TRANSFORMED = {value = "{USER}/alpha", transform = true}
SKIP_IF_SET = {value = "on", skip_if_set = true}
```
The `tool.pytest_env` tables keys are the environment variables keys to set. The right hand side of the assignment:
- if an inline table you can set options via the `transform` or `skip_if_set` keys, while the `value` key holds the
value to set (or transform before setting). For transformation the variables you can use is other environment
variable,
- otherwise the value to set for the environment variable to set (casted to a string).
### Via pytest configurations
In your pytest.ini file add a key value pair with `env` as the key and the environment variables as a line separated
list of `KEY=VALUE` entries. The defined variables will be added to the environment before any tests are run:
```ini
[pytest]
env =
HOME=~/tmp
RUN_ENV=test
```
Or with `pyproject.toml`:
```toml
[tool.pytest.ini_options]
env = [
"HOME=~/tmp",
"RUN_ENV=test",
]
```
### Only set if not already set
You can use `D:` (default) as prefix if you don't want to override existing environment variables:
```ini
[pytest]
env =
D:HOME=~/tmp
D:RUN_ENV=test
```
### Transformation
You can use existing environment variables using a python-like format, these environment variables will be expended
before setting the environment variable:
```ini
[pytest]
env =
RUN_PATH=/run/path/{USER}
```
You can apply the `R:` prefix to keep the raw value and skip this transformation step (can combine with the `D:` flag,
order is not important):
```ini
[pytest]
env =
R:RUN_PATH=/run/path/{USER}
R:D:RUN_PATH_IF_NOT_SET=/run/path/{USER}
```
