xUnit1002 Error

Test methods cannot have multiple Fact or Theory attributes

Cause

A test method has multiple Fact or Theory attributes.

A test method only needs one Fact or Theory attribute.

To fix a violation of this rule, remove all but one of the Fact or Theory attributes.

using Xunit;

public class xUnit1002
{
    [Fact, Theory]
    public void TestMethod()
    { }
}

using Xunit;

public class xUnit1002
{
    [Fact]
    public void TestMethod()
    { }
}

using Xunit;

public class xUnit1002
{
    [Theory]
    public void TestMethod()
    { }
