public void DistinctTest()
{
// ARRANGE
var list = new[] { "a", "aa", "aaa", "b", "bb", "bbb" };
// ACT

public void ShouldFilterOutDuplicateGcSettings()
{
var gcSettings = new[]
{
new GcBenchmarkSetting(GcMetric.TotalCollections, GcGeneration.Gen0, AssertionType.Throughput,
Assertion.Empty),
new GcBenchmarkSetting(GcMetric.TotalCollections, GcGeneration.Gen0, AssertionType.Total,

};
var distinctGcSettings = gcSettings.Distinct(GcBenchmarkSetting.GcBenchmarkDistinctComparer.Instance);
// according to normal equality, all 4 should be distinct as they have different assertion settings
Assert.Equal(4, gcSettings.Distinct().Count());
// but using our special EqualityComparer<T>, they really track only 2 distinct metrics
Assert.Equal(2, distinctGcSettings.Count());

{
var memorySettings = new[]
{
new MemoryBenchmarkSetting(MemoryMetric.TotalBytesAllocated,

};
var distinctMemorySettings = memorySettings.Distinct(MemoryBenchmarkSetting.MemoryBenchmarkDistinctComparer.Instance);
Assert.Equal(2, memorySettings.Length);
Assert.Equal(1, distinctMemorySettings.Count());
