# 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 category dotnet test --filter "TestCategory=Integration" # Exclude a category dotnet test --filter "TestCategory!=Slow" # Combine: class AND category dotnet test --filter "ClassName=MyNamespace.MyTestClass&TestCategory=Unit" # Either of two classes dotnet test --filter "ClassName=MyNamespace.ClassA|ClassName=MyNamespace.ClassB" ``` ## MTP filters — MSTest and NUnit MSTest and NUnit on MTP u...
