[ExcludeFromCodeCoverage] lets through lambdas, yield return and await #129
Description
This code
public class Class1 { [ExcludeFromCodeCoverage] public int F1(string input) { Func<char, int> f = (c => { return (int)c; }); return input.Select(x => { var l = new List<char> { x }; return l.Select(f).Last(); }).Sum(); } [ExcludeFromCodeCoverage] public IEnumerable<int> F2(string input) { foreach (char c in input) { yield return c; } } [ExcludeFromCodeCoverage] public async Task<string> F3(string input) { var f = new StreamReader(File.OpenRead(input)); var r = await f.ReadToEndAsync(); return r; } public static string F4(string input) { return input.ToUpperInvariant(); } [ExcludeFromCodeCoverage] public string F5(string input) { return input.ToUpperInvariant(); } } with a test to exercise method F4.
Expect just method F4 in the coverage file, with 100% coverage
Get 15.8% line coverage, with the lambda expressions in F1 and generated MoveNext methods in the implementations of F2 and F3 showing uncovered.
