pytest-api-core 1.0.2

Pytest API automation framework with custom HTML reporting, reusable fixtures, and fluent assertions

pytest-api-core

A reusable pytest API automation framework with fluent assertions, built-in auth strategies, environment-aware configuration, and a beautiful custom HTML report — packaged for Artifactory distribution.

Features

• APIClient — requests.Session wrapper with retry, timeout, and structured logging
• Fluent response assertions — assert_that(response).status_is(200).json_path("$.id").equals(1)
• Auth strategies — Bearer token, Basic, API Key (header/query), OAuth2 client credentials
• Environment config — Python settings.py classes + .env file + ENV_VAR overrides via api_config fixture
• Custom HTML report — self-contained report with charts, filterable table, captured logs, and request/response details
• Auto-registered pytest fixtures — zero boilerplate in consuming projects

Installation

From private PyPI

pip install pytest-api-core \
  --index-url https://pypi.example.com/simple/

With .env support (optional but recommended):

pip install "pytest-api-core[dotenv]"

Or add to requirements.txt / pyproject.toml:

pytest-api-core==1.0.0

---

Quick Start

1. Create environment settings

# config/settings.py
import os
from pytest_api_core.config.base_settings import BaseSettings

class DevSettings(BaseSettings):
    base_url = "https://api.dev.example.com"
    timeout  = 30
    verify_ssl = True
    headers  = {"Accept": "application/json", "Content-Type": "application/json"}

class StagingSettings(DevSettings):
    base_url = os.environ.get("API_BASE_URL", "https://api.staging.example.com")
    timeout  = 60

ENVIRONMENTS = {
    "dev":     DevSettings,
    "staging": StagingSettings,
}

2. Store secrets in .env (never commit this file)

# .env
BEARER_TOKEN=eyJhbGciOiJIUzI1NiIs...
API_KEY=super-secret-key

3. Configure pytest.ini

[pytest]

# ── Framework ────────────────────────────────────────────────────────────────
api_env             = dev
api_settings_module = config.settings
api_dotenv_file     = .env

# ── Report ───────────────────────────────────────────────────────────────────
addopts = --api-html-report=reports/{env}/report_{timestamp}.html -v
api_html_theme      = dark            # or "light"
api_html_title      = API Test Report # browser tab title
api_html_header     = API Test Report # page header text

# ── Logging ──────────────────────────────────────────────────────────────────
api_log_level       = INFO
log_cli             = true
log_cli_level       = INFO
log_cli_format      = %(asctime)s [%(levelname)-8s] %(name)s: %(message)s
log_cli_date_format = %H:%M:%S

4. Write tests

# tests/test_posts.py
from pytest_api_core.assertions import assert_that

def test_get_post(api_client):
    response = api_client.get("/posts/1")
    assert_that(response).status_is(200).json_path("$.id").equals(1)

def test_create_post(api_client):
    payload = {"title": "foo", "body": "bar", "userId": 1}
    response = api_client.post("/posts", json=payload)
    assert_that(response).status_is(201).has_key("id")

5. Run with HTML report

pytest tests/ --api-env=staging

The report is written to reports/staging/report_<timestamp>.html.

Configuration

Resolution order (highest → lowest priority)

Priority	Source
1	Shell / CI environment variables (API_BASE_URL, API_TOKEN, …)
2	--api-base-url CLI flag
3	ENVIRONMENTS[env] class in settings_module
4	Built-in defaults (http://localhost, timeout 30 s, …)

pytest.ini options

Option	Description	Default
api_env	Active environment name	dev
api_settings_module	Dotted path to settings module	—
api_dotenv_file	Path to .env file	.env
api_log_level	Log level for framework internals	WARNING
api_html_report	Output path for HTML report (supports {env}, {timestamp})	—
api_html_theme	Report theme: light or dark	dark
api_html_title	Browser tab title text	API Test Report
api_html_header	Page header text	API Test Report

CLI flags

Flag	Description
--api-env	Override active environment
--api-base-url	Override base_url
--api-log-level	Override framework log level
--api-html-report	Override HTML report path

Environment variables

Variable	Purpose
API_BASE_URL	Override base_url
API_TOKEN	Inject Bearer token (auto-applied by api_client)
API_ENV	Select environment
API_TIMEOUT	Override request timeout
API_VERIFY_SSL	Override SSL verification

---

Fixtures

Fixture	Scope	Description
api_config	session	Resolved config dict for the active env
api_client	session	Configured APIClient instance
api_bearer_auth	function	BearerAuth built from API_TOKEN env var
api_basic_auth	function	BasicAuth built from API_USERNAME / API_PASSWORD
api_key_auth	function	APIKeyAuth built from API_KEY_NAME / API_KEY_VALUE

Overriding api_client per project

# tests/conftest.py
import pytest
from pytest_api_core.auth.auth_handlers import BearerAuth
from pytest_api_core.client.api_client import APIClient
from pytest_api_core.config.env_loader import get_env

@pytest.fixture(scope="session")
def api_client(api_config):
    token = get_env("BEARER_TOKEN", required=True)
    client = APIClient(
        base_url=api_config["base_url"],
        auth=BearerAuth(token),
        timeout=api_config.get("timeout", 30),
        verify_ssl=api_config.get("verify_ssl", True),
        default_headers=api_config.get("headers"),
    )
    yield client
    client.close()

Publishing

Via GitHub Actions (Recommended)

Use the Publish to Public PyPI workflow for automated releases:

1. Go to Actions → Publish to Public PyPI
2. Click Run workflow
3. Enter version (e.g., 1.0.1) and enable/disable tests
4. Workflow will build, test, and publish to PyPI

See docs/PUBLISHING.md for detailed setup instructions.

# Upload to PyPI
twine upload dist/*

# Or upload to private registry
twine upload \
  --repository-url https://pypi.example.com \
