Cause
A fixture method (methods with AssemblyInitializeAttribute, AssemblyCleanupAttribute, ClassInitializeAttribute, or ClassCleanupAttribute) accesses restricted TestContext properties.
Rule description
Certain TestContext properties aren't available in fixture methods because they're specific to individual test execution:
Properties unavailable in class and assembly fixture methods:
TestDataTestDisplayNameDataRowDataConnectionTestNameManagedMethod
Properties unavailable in assembly-level fixture methods:
FullyQualifiedTestClassNameManagedType
How to fix violations
Remove the usage of restricted TestContext properties from fixture methods. Consider using alternative approaches for class/assembly initialization and cleanup that don't rely on test-specific context information.
When to suppress warnings
Don't suppress warnings from this rule. Accessing these properties in fixture methods can result in unexpected behavior or runtime errors.
