Analyze and summarize Allure test reports

Allure Report Summarizer

A Python utility for analyzing and summarizing Allure test reports. This tool extracts detailed test execution statistics, timing information, and test status data from Allure HTML reports, providing comprehensive insights into test suite performance.

Features

• Test Execution Statistics: Extracts total, passed, failed, broken, skipped, and unknown test counts
• Timing Analysis: Provides start time, stop time, and duration of test executions
• Pass Rate Calculation: Automatically calculates test suite pass rates
• Unique Test Tracking: Identifies and counts unique test cases by status
• JSON Export: Saves failed and passed test IDs to separate JSON files for further analysis
• Multiple Output Formats: Supports both console output and file-based summaries
• Robust File Handling: Handles various file encodings (UTF-8, Latin1, CP1252, ISO-8859-1)
• Environment Configuration: Configurable via environment variables

Installation

Requirements

• Python 3.6+
• Allure HTML report files

Install from PyPI

pip install allure-report-analyzer

Set environment variables

# Set the path for JSON output files (default: c:\reports\json_files)
export JSON_FILE_PATH="path/to/your/json/output"

# Set the Allure report directory path
export ALLURE_REPORT_PATH="path/to/allure/reports"

Usage

Command Line Usage

The CLI supports three main workflows:

1. Summarize a report from ALLURE_REPORT_PATH
2. Parse all matching Allure HTML reports in a directory with --all
3. Print runtime analytics from a generated JSON file with --stats

Example commands:

# Use the report directory from the environment variable
export ALLURE_REPORT_PATH="/path/to/allure/reports"
allure-analyzer

# Save failed test IDs
allure-analyzer --fail

# Save passed test IDs
allure-analyzer --pass

# Parse all Allure HTML files under the report directory
allure-analyzer --all

# Load runtime statistics from a JSON file
allure-analyzer --stats path/to/test_runtime_data.json

You can also pass a report directory as the first positional argument. When present, the script first checks ALLURE_REPORT_PATH; if that location is not available, it falls back to the supplied path.

The script rejects common typoed flags:

-all    # use --all
-stat   # use --stats
--stat  # use --stats

Default execution does the following:

1. Resolves the report directory from ALLURE_REPORT_PATH or the first positional argument
2. Summarizes the report when running in single-report mode
3. Generates aggregated runtime data
4. Removes duplicate test IDs while keeping the most recent execution

Python API Usage

from report_summarize import summarize_html_report, save_summary_to_file, get_unique_test_count

# Summarize a report
summary = summarize_html_report("path/to/report.html")
print(summary)

# Output:
# {
#     'start_time': '2024-03-01 10:00:00',
#     'stop_time': '2024-03-01 11:00:00',
#     'duration': '1 hours 0 minutes 0 seconds',
#     'total': 100,
#     'passed': 90,
#     'failed': 10,
#     'broken': 0,
#     'skipped': 0,
#     'unknown': 0,
#     'pass_rate': '90.00%'
# }

# Save summary to file
save_summary_to_file(summary, "report_summary.txt")

# Get detailed test statistics
test_stats = get_unique_test_count("path/to/report.html")
print(f"Failed tests: {len(test_stats['failed'])}")
print(f"Passed tests: {len(test_stats['passed'])}")

Advanced Usage

from report_summarize import (
    get_report_path,
    get_summary_message,
    get_file_size_in_mb,
    read_html_file,
    extract_test_data
)

# Get the latest report file path
report_path = get_report_path("/path/to/reports")

# Read HTML content with encoding handling
content = read_html_file(report_path)

# Extract test data
test_data = extract_test_data(content)

# Get file size
size = get_file_size_in_mb(report_path)
print(f"Report size: {size}")

# Generate formatted message
summary = summarize_html_report(report_path)
message = get_summary_message(summary)
print(message)

Configuration

Environment Variables

Variable	Description	Default
ALLURE_REPORT_PATH	Directory containing Allure HTML reports	Required (no default)
JSON_FILE_PATH	Directory for JSON output files	c:\reports\json_files

Output Files

The script can generate the following files in the JSON_FILE_PATH directory:

• failed_testscripts.json: List of failed test case IDs when --fail is used
• passed_testscripts.json: List of passed test case IDs when --pass is used
• test_runtime_data.json: Deduplicated runtime data used for runtime analysis

Temporary files created during aggregation are cleaned up automatically:

• processed_data.json
• test_execution.json

Examples

Basic Report Analysis

from report_summarize import summarize_html_report

# Analyze a single report
summary = summarize_html_report("allure-report/index.html")
for key, value in summary.items():
    print(f"{key}: {value}")

Batch Processing Multiple Reports

import os
from report_summarize import summarize_html_report

reports_dir = "/path/to/reports"
for filename in os.listdir(reports_dir):
    if filename.endswith('.html'):
        report_path = os.path.join(reports_dir, filename)
        summary = summarize_html_report(report_path)
        print(f"Report: {filename}")
        print(f"Pass Rate: {summary['pass_rate']}")

Runtime Statistics From JSON

python allure_report_summarizer/report_summarize.py --stats path/to/test_runtime_data.json

This command prints:

• overall pass, fail, and broken counts
• total and average runtime
• slowest tests
• tests with high scenario counts
• execution statistics grouped by report file

Custom Output Formatting

from report_summarize import summarize_html_report, get_unique_test_count

report_path = "allure-report/index.html"
summary = summarize_html_report(report_path)
test_stats = get_unique_test_count(report_path)

print("=== TEST EXECUTION SUMMARY ===")
print(f"Duration: {summary['duration']}")
print(f"Total Tests: {len(test_stats['total'])}")
print(f"Passed: {len(test_stats['passed'])}")
print(f"Failed: {len(test_stats['failed'])}")
print(f"Pass Rate: {summary['pass_rate']}")

if test_stats['failed']:
    print("\nFailed Test IDs:")
    for test_id in test_stats['failed'][:10]:  # Show first 10
        print(f"  - {test_id}")
    if len(test_stats['failed']) > 10:
        print(f"  ... and {len(test_stats['failed']) - 10} more")
