A plugin to use with Pytest to disable or restrict `socket` calls during
tests to ensure network calls are prevented.

---

## Features

- Disables all network calls flowing through Python\'s `socket` interface.

## Requirements

- [Pytest](https://github.com/pytest-dev/pytest) 6.2.5 or greater

## Installation

You can install `pytest-socket` via [pip](https://pypi.python.org/pypi/pip/)
from [PyPI](https://pypi.python.org/pypi):

```console
pip install pytest-socket
```

or add to your `pyproject.toml` for [poetry](https://python-poetry.org/):

```ini
[tool.poetry.dev-dependencies]
pytest-socket = "*"
```

## Usage

Run `pytest --disable-socket`, tests should fail on any access to `socket` or
libraries using socket with a `SocketBlockedError`.

To add this flag as the default behavior, add this section to your
[`pytest.ini`](https://docs.pytest.org/en/6.2.x/customize.html#pytest-ini):

```ini
[pytest]
addopts = --disable-socket
```

or add this to your [`setup.cfg`](https://docs.pytest.org/en/6.2.x/customize.html#setup-cfg):

```ini
[tool:pytest]
addopts = --disable-socket
```

or update your [`conftest.py`](https://docs.pytest.org/en/6.2.x/writing_plugins.html#conftest-py-plugins) to include:

```python
from pytest_socket import disable_socket

def pytest_runtest_setup():
    disable_socket()
```

If you exceptionally want to enable socket for one particular execution
pass `--force-enable-socket`. It takes precedence over `--disable-socket`.

To enable Unix sockets during the test run (e.g. for async), add this option:

```ini
[pytest]
addopts = --disable-socket --allow-unix-socket
```

To enable specific tests use of `socket`, pass in the fixture to the test or
use a marker:

```python
def test_explicitly_enable_socket(socket_enabled):
    assert socket.socket(socket.AF_INET, socket.SOCK_STREAM)


@pytest.mark.enable_socket
def test_explicitly_enable_socket_with_mark():
    assert socket.socket(socket.AF_INET, socket.SOCK_STREAM)
```

To allow only specific hosts per-test:

```python
@pytest.mark.allow_hosts(['127.0.0.1'])
def test_explicitly_enable_socket_with_mark():
    assert socket.socket.connect(('127.0.0.1', 80))
```

or for whole test run

```ini
[pytest]
addopts = --allow-hosts=127.0.0.1,127.0.1.1
```

### Frequently Asked Questions

Q: Why is network access disabled in some of my tests but not others?

A: pytest's default fixture scope is "function", which `socket_enabled` uses.
If you create another fixture that creates a socket usage that has a "higher"
instantiation order, such as at the module/class/session, then the higher order
fixture will be resolved first, and won't be disabled during the tests.
Read more in [this excellent example](https://github.com/miketheman/pytest-socket/issues/45#issue-679835420)
and more about [pytest fixture order here](https://docs.pytest.org/en/stable/fixture.html#fixture-instantiation-order).

This behavior may change in the future, as we learn more about pytest
fixture order, and what users expect to happen.

pytest plugin by [\@miketheman](https://github.com/miketheman).
