xUnit.net

Testing & QA

Unit testing framework for .NET

Official documentation (opens in a new tab)

Overview

xUnit.net is a supported alternative to MSTest and Reqnroll-driven acceptance tests when teams prefer xUnit conventions in .NET solutions.

Generated solutions ship with MSTest, coverage thresholds, and pipeline gates—extended by Reqnroll acceptance tests and Playwright UI checks where products demand higher assurance.

For client programs we map tests to business scenarios and non-functional requirements, keeping flaky suites out of mainline CI so teams trust green builds.

Quality is part of the platform story: from unit tests to deployed environments, we help you prove correctness before customers do.

Why we use it:

  • Consistent with CI test discovery
  • Cover critical domain and API paths
  • Pair with Reqnroll for BDD where needed
  • Avoid duplicate frameworks per repo
  • Fast feedback in Azure Pipelines on every pull request
  • Coverage and static analysis gates on main branches
  • Traceability from requirements to automated scenarios
