Description

One may not specify ParallelScope.Fixtures on a test method.

Motivation

To prevent tests that will fail at runtime due to improper construction.

How to fix violations

Example Violation

[Parallelizable(ParallelScope.Fixtures)]
[Test]
public void NUnit1010SampleTest()
{
    Assert.Pass();
}

Explanation

In the sample above, ParallelScope.Fixtures is specified.

However, in the context of a test method, a scope of Fixtures does not make sense. This scope only applies at the assembly or class level.

Fix

Remove the attribute:

[Test]
public void NUnit1010SampleTest()
{
    Assert.Pass();
}

Or apply this attribute at the class level:

[Parallelizable(ParallelScope.Fixtures)]
public class MyTests
{
    [Test]
    public void NUnit1010SampleTest()
    {
        Assert.Pass();
    }
}

Or use a different attribute that applies at the test level:

[Parallelizable(ParallelScope.Self)]
[Test]
public void NUnit1010SampleTest()
{
    Assert.Pass();
}

Configure severity

Via ruleset file.

Configure the severity per project, for more info see MSDN.

Via #pragma directive.

#pragma warning disable NUnit1010 // No ParallelScope.Fixtures on a test method.
Code violating the rule here
#pragma warning restore NUnit1010 // No ParallelScope.Fixtures on a test method.

Or put this at the top of the file to disable all instances.

#pragma warning disable NUnit1010 // No ParallelScope.Fixtures on a test method.

Via attribute [SuppressMessage].
