@event != @event

[kadamgreene]

I'm not sure if this is a problem with the testing framework or the compiler itself...

I have the following code:

public class MyState
{
    public void Apply(MyEvent @event) { }
}

The CodeFixProvider generates the method. When I run the code through the CodeFixProvider testing framework. I get this error:

Test method AggregateGrainCodeFixProviderTests.TestCodeFixForMissingApplyMethod threw exception: 
System.InvalidOperationException: Context: Iterative code fix application
items not equal.  expected:'event' actual:'@event'

When I trace through the code, I eventually get to the CodeActionTest<TVerifier>.AssertTokensEqual and the expectedValue is SyntaxToken IdentifierToken @event and the actualValue is SyntaxToken IdentifierToken @event, but when I inspect expectedValue, Value is event, but when I inspect actualValue, Value is @event (but both have a Text value of @event).

I think the testing framework will assert that the syntax tree produced after applying the codefix being tested will exactly match what the compiler produces if it would parse the same text.

Hence, your codefix is expected to produce the SyntaxToken exactly as the compiler would parse the text. So I assume somewhere in your codefix, you'are creating a SyntaxToken for @event and the token doesn't exactly match what the compiler would have produced.

If you use CodeActionValidationMode.None, does it make your test pass? This is not to say you should use CodeActionValidationMode.None
