JUnit Validator Online

This tool validates JUnit XML reports produced by Java test suites. It targets developers, QA engineers, and CI/CD teams that rely on accurate test result data for dashboards, failure analysis, and release decisions. The primary problem is malformed XML, missing fields, or inconsistent timing data that break downstream analytics. By validating against common structural expectations and optional rules, it helps maintain trustworthy test artifacts when reports are generated in CI pipelines or local builds. Example scenarios include catching duplicate test ids, negative durations, or suites that do not align with expected nesting.
Conceptually, the validator parses the XML, builds a model of suites, test cases, and properties, and applies standard checks (schema conformance, required fields, and non-negative times). It can enforce version compatibility with JUnit 4/5 and flag discrepancies that break downstream dashboards.
Unique value lies in its domain-specific checks, such as duplicate test IDs, inconsistent duration units, and missing stack traces for failed tests, all without requiring local tooling. It supports batch validation, providing per-file reports suitable for pull requests and CI logs.
Core features include strict XML parsing, customizable validation rules, detailed error reporting, and export of JSON or CSV summaries. Use cases span pre-commit validation, CI pipeline integration, and quality audits of test results across Java projects.
