Description

The type of the actual argument is not a string and hence cannot be used with a String Constraint.

Motivation

Assertions with string constraints and non-string actual value will fail with error.

How to fix violations

Fix actual value or use appropriate constraint.

Configure severity

Via ruleset file

Configure the severity per project, for more info see MSDN.

Via .editorconfig file

# NUnit2024: Wrong actual type used with String Constraint
dotnet_diagnostic.NUnit2024.severity = chosenSeverity

where chosenSeverity can be one of none, silent, suggestion, warning, or error.

Via #pragma directive

#pragma warning disable NUnit2024 // Wrong actual type used with String Constraint
Code violating the rule here
#pragma warning restore NUnit2024 // Wrong actual type used with String Constraint

Or put this at the top of the file to disable all instances.

#pragma warning disable NUnit2024 // Wrong actual type used with String Constraint
