Handling Responses
editresponse.ShouldBeValid(); var commits = response.Aggregations.Histogram("commits"); commits.Should().NotBeNull(); commits.Buckets.Should().NotBeNull(); commits.Buckets.Count.Should().BeGreaterThan(0); foreach (var item in commits.Buckets) item.DocCount.Should().BeGreaterThan(0);
