Description
The type of parameters provided by the TestCaseSource must match the type of parameters in the Test method.
Note that the current implementation only works for single parameters.
Motivation
A TestCaseSourceAttribute is used to pass parameters to a test method, but the test method expects a different type of parameter.
private static readonly IEnumerable<string> NUnitNameSpaces = new[] { ".NUnit", ".NUnitExtensions" };
[TestCaseSource(nameof(NUnitNameSpaces))]
public void IsNUnit(int n)
{
}
How to fix violations
Match the type of parameters between the test data and the test method.
Configure severity
Via ruleset file
Configure the severity per project, for more info see MSDN.
Via .editorconfig file
# NUnit1030: The type of parameter provided by the TestCaseSource does not match the type of the parameter in the Test method
dotnet_diagnostic.NUnit1030.severity = chosenSeverity
where chosenSeverity can be one of none, silent, suggestion, warning, or error.
Via #pragma directive
#pragma warning disable NUnit1030 // The type of parameter provided by the TestCaseSource does not match the type of the parameter in the Test method
Code violating the rule here
#pragma warning restore NUnit1030 // The type of parameter provided by the TestCaseSource does not match the type of the parameter in the Test method
Or put this at the top of the file to disable all instances.
#pragma warning disable NUnit1030 // The type of parameter provided by the TestCaseSource does not match the type of the parameter in the Test method
