assertion-quality

You can detect missing or shallow assertions in xUnit or NUnit test suites by analyzing assertion variety and depth across your test files. This audit identifies zero-assertion tests, trivial-only checks, and tautological patterns, producing metrics that flag missing negative, exception, or state verification for improved correctness coverage.

Tautological assertions in .NET unit testing are self-referential checks that verify mock setups rather than actual system behavior, creating false confidence. Auditing your test suite identifies these quality risks alongside missing deep structural or side-effect verification, ensuring tests meaningfully validate correctness across MSTest, xUnit, NUnit, and TUnit frameworks.

To audit assertion diversity across a .NET test project, categorize assertions by framework and compute suite-wide and per-test metrics. This analysis quantifies reliance on single assertion types like equality, identifies over-concentration, and highlights missing negative or exception checks, yielding a metrics report with recommendations for strengthening behavior verification.

Yes, assertion quality analysis works with MSTest, xUnit, NUnit, and TUnit frameworks. The analysis categorizes assertions across all these frameworks, computing metrics to find trivial patterns, missing state checks, and tautological assertions, ensuring your test suite meaningfully verifies correctness regardless of the testing framework used.

Unit tests may pass without verifying actual behavior when they rely on shallow, trivial, or missing assertions like checking only if an object is not null. Analyzing assertion depth exposes these false-confidence patterns by flagging missing negative, exception, state, and deep structural checks across your .NET test suites.

No, this tool cannot automatically write new assertions. It strictly analyzes the variety and depth of existing assertions across your test files to identify quality risks and missing checks, producing actionable recommendations and metrics rather than generating new test code or modifying your existing test suites.
