xUnit1029

"Local functions cannot be test functions"

Cause

A test method must be directly inside a class. Local functions (that is, functions defined inside other code blocks) are not supported.

Reason for rule

xUnit.net does not look for local functions to find tests, as they are not supported.

How to fix violations

To fix a violation of this rule, move the test function to class-level.

Examples

Violates

using Xunit;

public class xUnit1029
{
    private void NonTestMethod()
    {
        [Fact]
        void TestMethod()
        {
            // ...
        }
    }
}

Does not violate

using Xunit;

public class xUnit1029
{
    [Fact]
    void TestMethod()
    {
        // ...
    }

    private void NonTestMethod()
    {
        // ...
    }
}
