Can I track test performance over time?

Yes, the tool maintains a history in the .testrunner directory and provides 'stats' and 'regressions' commands to visualize health trends.

When should I use this instead of the standard dotnet test command?

Use this skill when your standard test runs hang, crash the process (OOM/Stack Overflow), or when you have a flaky suite that requires regression tracking.

How does the isolation feature identify failing tests?

It splits the test tree into branches and runs them separately. If a branch hangs or crashes, it drills down further until the specific culprit test is identified.

Does this tool require a manual installation process?

No, it utilizes dnx to run from source. As long as you have the .NET 10 SDK or later, it will automatically handle the tool execution.

セキュリティとテスト

Resolves .NET test suite instability by isolating hanging, crashing, and flaky tests through advanced hang detection and regression tracking.

Asynkron.TestRunner is a specialized diagnostic tool for .NET developers struggling with unstable test suites that standard tooling cannot handle. It excels at identifying the root causes of process-killing errors such as Stack Overflow, Out of Memory, and Access Violations by automatically isolating tests into separate branches. By providing historical tracking, trend visualization, and automated hang detection, it allows developers to pinpoint flaky tests and monitor regression patterns over time, ensuring CI/CD pipelines remain reliable even when dealing with complex or legacy test suites.
