Skill instructions
Test Filter Syntax Reference Filter syntax depends on the platform and test framework. VSTest filters (MSTest, xUnit v2, NUnit on VSTest) bash dotnet test --filter <EXPRESSION Expression syntax: <Property<Operator<Value[|&<Expression] Operators: | Operator | Meaning | |----------|---------| | = | Exact match | | != | Not exact match | | ~ | Contains | | !~ | Does not contain | Combinators: | (OR), & (AND). Parentheses for grouping: (A|B)&C Supported properties by framework: | Framework | Properties | |-----------|-----------| | MSTest | FullyQualifiedName, Name, ClassName, Priority, TestCategory | | xUnit | FullyQualifiedName, DisplayName, Traits | | NUnit | FullyQualifiedName, Name, Priority, TestCategory | An expression without an operator is treated as FullyQualifiedName~<value. Examples (VSTest): bash Run tests whose name contains "LoginTest" dotnet test --filter "Name~LoginTest" Run a specific test class dotnet test --filter "ClassName=MyNamespace.MyTestClass" Run tests in a categ
