xUnit1004

Cause

Tests should not be skipped long term. This analyzer highlights skipped tests for better visibility.

Reason for rule

Skipping tests should be considered a temporary mechanism, and as such, tests which are skipped are highlighted so they're easier to see and to allow the developer to fix the issue.

For v3 test projects, using SkipWhen or SkipUnless suppresses this analyzer, since that's used to conditionally skip tests based on the testing environment.

How to fix violations

To fix a violation of this rule, you will typically employ one of two strategies:

• If the test is temporarily skipped because it's broken or flaky, then repair the test and un-skip it.
• If the test is deemed unreliable or unnecessary, the best strategy may be to just delete the test.

Examples

Violates

For v2 and v3

using Xunit;

public class xUnit1004
{
    [Fact(Skip = "This is a flaky test")]
    public void TestMethod() { }
}

Does not violate

For v2 and v3

using Xunit;

public class xUnit1004
{
    [Fact]
    public void TestMethod() { }
}

For v3 only

using System;
using Xunit;

public class xUnit1004
{
    [Fact(Skip = "This test requires Windows",
          SkipUnless = nameof(OperatingSystem.IsWindows),
          SkipType = typeof(OperatingSystem))]
    public void TestMethod() { }
}
