pytest-bazel

0.1.6 verified Fri May 01 auth: no python deprecated

A pytest plugin that collects and runs tests in Bazel workspaces. Currently at version 0.1.6 with no active maintenance; last release was in 2020. Works by integrating pytest with Bazel's test runner, enabling parallel execution and caching. Suitable for Python projects using Bazel as their build system.

pip install pytest-bazel

Common errors

error ERROR: Bazel binary not found ↓

cause Bazel is not installed or not in PATH.

fix

Install Bazel (https://bazel.build) or add its location to PATH.

error ModuleNotFoundError: No module named 'pytest_bazel' ↓

cause pytest-bazel is not installed in the environment.

fix

Run pip install pytest-bazel in the correct Python environment.

Warnings

deprecated pytest-bazel is no longer actively maintained. Consider migrating to `rules_python` or `bazel_pytest`. ↓

fix Switch to `rules_python` integration with native pytest support, or use `pip install bazel_pytest` for an alternative.

gotcha The plugin requires that Bazel and Python are on PATH. Misconfiguration may lead to 'Bazel not found' errors. ↓

fix Ensure Bazel is installed and available in your shell environment.

Imports

pytest_bazel

wrong

import pytest_bazel

correct

pytest_bazel is a plugin; no direct import needed. Use `--bazel` flag with pytest.

Do not import directly; plugin is auto-discovered when installed.

Quickstart

Run pytest with Bazel support.

# Ensure pytest-bazel is installed
# Add to BUILD file or run:
pytest --bazel --bazel-python=$(which python) tests/
