v2 v3 AOT   Warning

xUnit1073

"Collection definition is never used"

Cause

A violation of this rule occurs when a collection definition does not have any references from any tests.

Reason for rule

This rule triggers most often in two situations:

• The collection definition name is misspelled.
• A previously used collection definition is no longer needed because tests that referenced it were deleted (or removed from the collection).

How to fix violations

To fix a violation of this rule, either fix the spelling mistake or remove the unused collection definition.

Examples

Violates

using Xunit;

[CollectionDefinition("MyCollection")]
public class xUnit1073Collection
{ }

[Collection("TheCollection")]
public class xUnit1073
{
    [Fact]
    public void TestMethod() { }
}

Does not violate

using Xunit;

[CollectionDefinition("MyCollection")]
public class xUnit1073Collection
{ }

[Collection("MyCollection")]
public class xUnit1073
{
    [Fact]
    public void TestMethod() { }
}

Note

This is a post-compile analyzer, so it may not show up in real time (or highlighted in the source code). It will be reported when the test project is compiled.
