Bobcat | Integration testing for .NET

Author, specify, and supervise integration tests in .NET.

Author

Behavior Driven Development with ordinary xUnit, TUnit, NUnit or MSTest tests against any .NET application. Keep your existing testing tools, and let Bobcat render the tests as human readable specifications through decorated step helpers and marker comments.

Write your first specification

Specify

Spec-driven development end to end -- executable specifications that still read as requirements, with tables, decision tables, set verification and partial objects for the data-intensive cases.

Specifications with code

Supervise

Make a big integration suite worth trusting -- split across worker processes, resources isolated per lane, retry budgets, and flakiness reported honestly instead of buried.

Make existing tests more reliable

Event Modeling and the Critter Stack

Optional, and the best way in for a Wolverine, Marten, Polecat or Fisher application. Import an Event Model as C#, write specifications in a ready-made Given/When/Then vocabulary, bind each one to its slice, and see which slices the specifications prove.

Build from an Event Model

Observe

The free bobcat ui serves a live run board and the Event Model canvas, colouring every slice from the runs of the specifications bound to it, with results files and a JSON report for everything else.

Watch a run

Built for AI agents

An optimized feedback loop for AI agent development. Customize the telemetry to describe what the system actually did during a failed test run instead of just saying that it failed, CLI queries over runs and specifications, and warm re-runs in seconds -- so a coding agent can diagnose a red suite and fix it without a human reading the output for it.
