testhide-pytest-plugin 0.2.5

A pytest plugin for creating incremental XML test reports for Testhide system.

Testhide Pytest Plugin

A professional-grade pytest plugin that generates robust JUnit-style XML reports. This plugin was designed to solve real-world CI/CD challenges by ensuring data integrity during test failures and providing full support for parallel test execution.

Key Features

• Incremental Reporting: Every single test result is saved immediately, guaranteeing that partial results are available even if a test run is catastrophically interrupted.
• Full pytest-xdist Compatibility: The plugin uses a robust temporary file and merge strategy, enabling it to work flawlessly with parallel test execution (-n X).
• pytest-rerunfailures Support: Every rerun of a failing test is logged as a separate <testcase> in the final report, providing a complete and accurate picture of flaky tests.
• JIRA Integration: Automatically enriches failure reports with information from JIRA, linking test failures to known bugs and their statuses.
• Clean Stack Traces: Automatically removes internal "noise" from pytest and pluggy calls in stack traces, leaving only the relevant information from your application and test code.
• Atomic & Safe Writes: Uses a temporary directory and a final, atomic merge to ensure the report file is never corrupted, even under heavy load or across multiple concurrent builds on the same agent.

Installation

pip install testhide-pytest-plugin

Usage

Basic Run

To activate the plugin and generate a report, use the --report-xml option:

pytest --report-xml=junittests.xml

Parallel Execution (pytest-xdist)

The plugin is fully compatible with pytest-xdist out of the box. Simply add the -n flag to run tests in multiple processes. The plugin will automatically handle and merge the results from all worker nodes.

pytest -n auto --report-xml=junittests.xml

Rerunning Failed Tests (pytest-rerunfailures)

The plugin works seamlessly with pytest-rerunfailures. Every attempt of a failing test will be recorded in the final report, allowing for accurate tracking of test instability.

pytest --reruns 5 --report-xml=junittests.xml

JIRA Integration

The plugin can automatically enrich failure reports with information from JIRA, linking test failures to known bugs and their statuses. There are two ways to configure this integration.

Method 1: Command-Line Arguments

You can enable JIRA integration by providing the connection details as command-line options. The integration is activated automatically when all three parameters are present.

• --jira-url: The URL of your JIRA instance.
• --jira-username: The username for the connection.
• --jira-password: The password or API token for the user.

pytest --report-xml=junittests.xml \
       --jira-url="[https://jira.yourcompany.com](https://jira.yourcompany.com)" \
       --jira-username="my-bot" \
       --jira-password="your-api-token"

Method 2: Programmatic Configuration (for Frameworks)

If you are developing a test framework plugin and manage credentials in a central configuration object (e.g., a YAML file), you can programmatically set the JIRA options. This avoids exposing credentials in CI scripts. Use the pytest_cmdline_main hook in your own plugin to set the configuration options before the testhide-plugin is configured.

import pytest

class MyFrameworkPlugin:
    @pytest.hookimpl(tryfirst=True)
    def pytest_cmdline_main(self, config):
        # Assuming ConfigApp loads your central configuration
        # from a file or environment variables.
        from my_framework.config import ConfigApp
        
        config.option.jira_url = ConfigApp.jira.url
        config.option.jira_username = ConfigApp.jira.username
        config.option.jira_password = ConfigApp.jira.password

Extending the Plugin (For Framework Developers)

testhide-pytest-plugin provides custom hooks for integration with your own plugins, allowing you to inject project-specific metadata into the report.

Example implementation in your plugin:

pytest_testhide_add_metadata(plugin)

This hook allows you to add metadata at the session level (e.g., build information, branch name, etc.). It must return a list of (name, value) tuples.

from pytest import hookimpl

class MyFrameworkPlugin:
    @hookimpl
    def pytest_testhide_add_metadata(self, plugin):
        return [
            ('build', '1.2.3'),
            ('branch', 'develop')
        ]

pytest_testhide_get_test_case_properties(item, report)

This hook allows you to add data at the individual test case level (e.g., a docstring, steps to reproduce, or artifact links). It must return a list of (name, value) tuples.

from pytest import hookimpl

class MyFrameworkPlugin:
    @hookimpl
    def pytest_testhide_get_test_case_properties(self, item, report):
        properties = []
        if item.obj and item.obj.__doc__:
            properties.append(('docstr', item.obj.__doc__.strip()))
        
        # Example of adding an artifact link
        if hasattr(item, 'artifact_url'):
            properties.append(('attachment', item.artifact_url))
            
        return properties
