dotnet-test

A workflow for running selected .NET tests with xUnit, a popular testing framework for .NET. It builds the whole solution first, then runs only the chosen test project or matching tests.

In plain words
What is it for?
Use it to build a .NET solution, run one test project, or select xUnit tests by method name, class name, or theory parameter.
Why use it?
It catches compilation problems before testing and avoids rebuilding unchanged code during focused test runs. Filters help narrow a run to a particular test method, class, or parameter.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dotnet-test scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

98% identical to dotnet-test — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

.NET Test Runner

Run .NET tests selectively using a build-first, test-targeted workflow optimized for development speed.

Core Workflow

Follow this workflow to run tests efficiently:

Step 1: Build Solution First

Build the entire solution with minimal output to catch compile errors early:

dotnet build -p:WarningLevel=0 /clp:ErrorsOnly --verbosity minimal

Step 2: Run Specific Project Tests

Run tests for the specific test project with --no-build to skip redundant compilation:

dotnet test path/to/project --no-build --verbosity minimal

Step 3: Filter When Targeting Specific Tests

Narrow down to specific tests using filter expressions:

# By method name using FullyQualifiedName (recommended)
dotnet test --no-build --filter "FullyQualifiedName~MyTestMethod"

# By class name using FullyQualifiedName (recommended)
dotnet test --no-build --filter "FullyQualifiedName~MyTestClass"

# By parameter values in Theory tests (xUnit)
dotnet test --no-build --filter "DisplayName~paramValue"

# Combined filters
dotnet test --no-build --filter "FullyQualifiedName~Create|FullyQualifiedName~Update"

Note: Properties Name~ and ClassName= may not work reliably. Use FullyQualifiedName~ instead.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
