Allure Report
Allure Report is an open-source reporting framework that turns raw automated test results into a detailed, interactive HTML report — showing pass/fail trends, execution history, screenshots, logs, and step-by-step breakdowns per test — rather than the plain text or XML output most test runners produce natively.
Allure plugs into most major test frameworks (PyTest, JUnit, TestNG, Cucumber, and others) via language-specific adapters, collecting result data during a test run and rendering it afterward as a browsable report with drill-down detail — failure stack traces, attached screenshots, and a visual timeline of each test's steps.
Its dashboard view is especially useful for spotting patterns across a whole suite — flaky tests that fail intermittently, trends across recent runs, and categorized failure types — turning a wall of pass/fail text into something a team can actually review together after a CI run, rather than someone manually scrolling through raw logs.
