yanalyzers's Issues

The fixer for Y0002 does not do anything for generics

Maybe this is a known limitation? var myList = Array.Empty<string>().ToList(); will suggest to use an explicit type, but the fixer does nothing, I'd hoped for a suggested change to List<string> myList = Array.Empty<string>().ToList(); .

(Yes one can argue that the type really is apparent here, but that's not the point. I just wanted a simple one-liner to demonstrate that the fixer doesn't do what I hoped).

New analyzer: Flag public methods in test classes that doesn't have a test attribute.

xUnit

Whenever there is a class containing at least a method with [Fact] or [Theory], ensure all other public methods having one of these attributes.

MSTest

Analyze classes marked with [TestClass] and look for any missing [TestMethod] (or [DataSource]) on a public method.

NUnit

Analyze classes marked with [TestFixture] and look for any missing [Test] or [Theory].

The form foreach (var (a, b) in x) should be converted into foreach ((TypeA a, TypeB b) in x)
