pytest-vulture 2.2.1

A pytest plugin to checks dead code with vulture

This plugin enables you to run vulture (https://pypi.org/project/vulture/) alongside pytest, allowing for dead code detection during your testing process.

Sample Usage

To integrate vulture with pytest and find dead code, use the following commands:

1. Basic Usage Run vulture with pytest to check for dead code:

   pytest --vulture

2. Custom Configuration Specify a custom configuration file path:

   pytest --vulture --vulture-cfg-file=/path/to/vulture.ini

   Note: By default, the tool looks for configuration files in the following order:

   • pyproject.toml

   • tox.ini

   • vulture.ini

Ignoring Vulture Messages

You can ignore specific warnings from vulture directly in the source code. Here’s how:

• Ignore Specific Lines:

  def test_function():
      unused_variable = 42  # vulture: ignore

• Ignore Entire Methods:

  def ignored_function():  # vulture: ignore
      pass

• Ignore Classes:

  class IgnoredClass:  # vulture: ignore
      pass

Configuring with pyproject.toml

Here’s an example of how to configure vulture using pyproject.toml:

[tool.vulture]
# Exclude specific paths (e.g., test directories)
exclude = [
    "*/test/*",
]

# Ignore specific files in the `pytest` output (but they are still checked by `vulture`)
ignore = [
    "src/some_ignored_file.py",
]

# Ignore specific function or variable names
ignore-names = [
    "deprecated_function",
]

# Ignore decorators
ignore-decorators = [
    "@app.route",
    "@celery.task",
]

# Ignore specific types of messages (e.g., imports)
ignore-types = [
    "import",
]

# Define the source path
source-path = "src"

Configuring with .ini Config Files

Here’s an example of how to configure vulture using an .ini file:

[vulture]
exclude =
    */test/*  # Usually exclude tests as they may cover dead code

ignore =
    src/some_ignored_file.py

ignore-names =
    deprecated_function

ignore-decorators =
    @app.route
    @celery.task

ignore-types =
    attribute
    variable
