xUnit1008 Warning

Test data attribute should only be used on a Theory

Cause

This is triggered by forgetting to put the [Theory] attribute on a test method with data attributes.

Reason for rule

If the test method does not have a [Theory] attribute on it, then the test will not run.

How to fix violations

To fix a violation of this rule, either:

Add a [Theory] attribute to the test method
Remove the theory data attributes

Examples

Violates

using Xunit;

public class xUnit1008
{
    [InlineData(42)]
    public void TestMethod(int _) { }
}

Does not violate

using Xunit;

public class xUnit1008
{
    [Theory]
    [InlineData(42)]
    public void TestMethod(int _) { }
}

using Xunit;

public class xUnit1008
{
    public void TestMethod(int _) { }
}
