v2 v3   Error

xUnit1010

"The value is not convertible to the method parameter type"

Cause

This rule is triggered by having data in an [InlineData] attribute which is not compatible with the parameter type.

Reason for rule

Mismatched data vs. parameter type results in a runtime error where the test is not able to run.

How to fix violations

To fix a violation of this rule, change either the data or the parameter type to match.

Examples

Violates

using Xunit;

public class xUnit1010
{
    [Theory]
    [InlineData("42")]
    public void TestMethod(int _) { }
}

Does not violate

using Xunit;

public class xUnit1010
{
    [Theory]
    [InlineData("42")]
    public void TestMethod(string _) { }
}

using Xunit;

public class xUnit1010
{
    [Theory]
    [InlineData(42)]
    public void TestMethod(int _) { }
}
