Code inspection: NUnit. Ignored parameter attribute.

This inspection reports parameter data attributes that NUnit will ignore because another parameter data source has already been specified for the same parameter. For example, combining [Values], [Range], or [Random] on one parameter can leave one of them unused.

Removing the ignored attribute makes it clear which data source NUnit will actually use.

Example

                [Test]
                [Sequential]
                public void Test(
                    [Values(1, 2, 3)] [Random(100, 200, 5)] int x)
                {
                }
            

                [Test]
                [Sequential]
                public void Test(
                    [Values(1, 2, 3)] int x)
                {
                }
