xUnit1054

"Properties used for conditional skipping must be public, static, and return bool"

Cause

A violation of this rule occurs when a public static property is required for SkipUnless or SkipWhen but one was not found (or it does not return bool as required).

Reason for rule

There are a few ways you can violate this rule:

• The named property does not exist
• The named property is not static
• The named property is not public
• The named property does not return bool

This rules applies everywhere you see SkipUnless and SkipWhen; that is, [Fact] and [Theory] (and friends) as well as data attributes like [MemberData].

How to fix violations

To fix a violation of this rule, ensure the named property exists, is public, is static, and returns bool.

Examples

Violates

using Xunit;

public class xUnit1054
{
    protected string AlwaysTrue => "yes";

    [Fact(Skip = "Conditionally Skipped", SkipWhen = nameof(AlwaysTrue))]
    public void NonPublic_Fact() { }
}

Does not violate

using Xunit;

public class xUnit1054
{
    public static bool AlwaysTrue => true;

    [Fact(Skip = "Conditionally Skipped", SkipWhen = nameof(AlwaysTrue))]
    public void NonPublic_Fact() { }
}
