From 25e8dd5d4b72a6d04c2bcf6b04eef1c7d3a27439 Mon Sep 17 00:00:00 2001 From: sethorpe Date: Thu, 6 Nov 2025 17:46:37 -0800 Subject: [PATCH] Add ATTACH_ON_FAILURE environment variable feature Implements automatic HTTP request/response recording when ATTACH_ON_FAILURE=true. When enabled, the pytest hook automatically attaches exchanges to Allure on test failure. Changes: - Modified client.py to check ATTACH_ON_FAILURE env var - Records exchanges silently without immediate attachment - Pytest hook attaches on failure for automatic debugging Tests Added: - test_attach_on_failure.py: Unit test with mock transport - test_pytest_hook_attach_on_failure.py: Hook integration test - test_attach_on_failure_integration.py: Real Spotify API validation - test_attach_on_failure_demo.py: Demo test (skipped by default) Other: - Fixed Makefile serve-report target to use poetry run All tests passing: 24/24 (1 skipped demo test) --- Makefile | 2 +- src/api_testing_framework/client.py | 22 ++-- tests/spotify/test_attach_on_failure_demo.py | 44 ++++++++ .../test_attach_on_failure_integration.py | 103 ++++++++++++++++++ tests/test_attach_on_failure.py | 59 ++++++++++ tests/test_pytest_hook_attach_on_failure.py | 66 +++++++++++ 6 files changed, 288 insertions(+), 8 deletions(-) create mode 100644 tests/spotify/test_attach_on_failure_demo.py create mode 100644 tests/spotify/test_attach_on_failure_integration.py create mode 100644 tests/test_attach_on_failure.py create mode 100644 tests/test_pytest_hook_attach_on_failure.py diff --git a/Makefile b/Makefile index 6c98320..05d15ba 100644 --- a/Makefile +++ b/Makefile @@ -24,7 +24,7 @@ report: # Serve the Allure report interactively serve-report: - python scripts/allure_helper.py --serve + poetry run python scripts/allure_helper.py --serve # Clean test artifacts and reports clean: diff --git a/src/api_testing_framework/client.py b/src/api_testing_framework/client.py index 9f3576c..a46eb75 100644 --- a/src/api_testing_framework/client.py +++ b/src/api_testing_framework/client.py @@ -175,35 +175,43 @@ def _request( path: URL path relative to base_url params: Query parameters for the request json: JSON body for the request - attach: If True, attach request/response to Allure report + attach: If True, attach request/response to Allure report immediately Returns: Parsed JSON response as dict Raises: APIError: If the response status indicates an error + + Environment Variables: + ATTACH_ON_FAILURE: If "true", records request/response for all calls. + Pytest hook can then attach on test failure.
