writing-mstest-tests

ALWAYS USE when asked to fix, rewrite, update, improve, modernize, show corrected code for, or explain existing MSTest tests or MSTest-specific configuration. Use for "review" when corrected code or edits are wanted, even for one pasted assertion or passing tests with bad failure output. Covers expected/actual labels; generic Boolean, collection, string, numeric, null, identity, exception, hard-cast, and object[] checks; TestContext/lifecycle; timeout/cancellation; OS/CI conditions, retry, cleanup, parallelization, MSTest.Sdk project setup, and MSTESTxxxx. Honor the installed MSTest version. DO NOT USE to design new test cases (code-testing), perform report-only audits, create project files rather than explain MSTest setup, run tests, migrate frameworks, or handle non-MSTest/non-.NET code.

# Writing MSTest Tests

Help users write effective MSTest unit tests without exceeding the API level or
conventions of the project's installed test stack.

## Repository overlay

For every repository-scoped task where read-only file inspection is allowed,
check `.agents/skill-overlays/dotnet-test/writing-mstest-tests.md` at the
repository root before any other discovery. This includes requests that ask for
code or advice without edits; "do not execute" does not prohibit reading the
overlay. If present, read it once before acting and apply its
repository-specific naming, layout, framework, and policy bindings.
Require its frontmatter to declare `core: dotnet-test/writing-mstest-tests`,
