[ FAILED ] CompletionTestNoExplicitMembers.StructTemplate
[ FAILED ] CompletionTestNoExplicitMembers.ExplicitStructTemplateSpecialization
[ FAILED ] CompletionTestMethodDeclared.ExplicitStructTemplateSpecialization
[ FAILED ] CompletionTestSpecialMethodsDeclared.Struct
[ FAILED ] CompletionTestSpecialMethodsDeclared.StructTemplate
[ FAILED ] CompletionTestSpecialMethodsDeclared.ExplicitStructTemplateSpecialization
