xUnit9003

"Type must have a single public non-static constructor"

Cause

A violation of this rule occurs when a type does not a single public constructor.

Reason for rule

When this rule is violated, it's because the source generator either found 0 public constructors, or found more than one, that met the requirements (public, non-static, non-[Obsolete]).

This is most commonly shown for types used as fixtures.

How to fix violations

To fix a violation of this rule, ensure there is only a single public, non-static, non-[Obsolete] constructor.

Examples

Violates

using Xunit;

public class xUnit9003 : IClassFixture<MyFixture>
{
    [Fact]
    public void TestMethod() { }
}

public class MyFixture
{
    public MyFixture() { }
    public MyFixture(int _) { }
}

Does not violate

using Xunit;

public class xUnit9003 : IClassFixture<MyFixture>
{
    [Fact]
    public void TestMethod() { }
}

public class MyFixture
{
    public MyFixture(int _) { }
}
