pytest-json-ctrf

CTRF for pytest

Pytest implementation of Common Test Report Format (CTRF) for test results.
Test report will be generated in JSON format.
Test report can be used to prettify the report in GitHub Actions with github-actions-ctrf.
Do not worry if report in GitHub does not appear immediately. It takes some time to process the report.

Features

• Generates JSON report
• Tested to work correctly with and without pytest-xdist
• Tested to get browser name from pytest-playwright
• Parametrized tests are supported and reported as 1 test with multiple retries

Installation

pip install pytest-json-ctrf

Usage

generate report.json file in the root directory of the project. File path is mandatory

pytest --ctrf report.json

Json exampe

Report Example

Technical details

For future me and others who are interested in the technical details of the implementation.
The main idea is to handle xdist plugin because without it collecting report is quite straightforward.
By the example of putest-json-report plugin, I have learned that different plugins can be registered for the controller and workers node.
The pytest_runtest_logreport hook in the controller node is used to collect the test results from all the nodes so other nodes can just add some details to the TestReport object.

• https://github.com/infopulse/Playwright-course-python -> The report will be used in the demo project as +1 report option

Roadmap

• Add screenshots handling
• Add hooks for the report extension
