should be able to unit test Nest.ElasticClient

gistfile1.cs

var settings = A.Fake<IConnectionSettings>();
var connection = A.Fake<IConnection>();

A.CallTo(() => settings.DefaultIndex).Returns("nest_test_data");

var value = new ConnectionStatus(File.ReadAllText(@"InversionOfControl.json"));

A.CallTo(() =>
	connection.PostSync(
		A<string>.That.Contains("nest_test_data/elasticsearchprojects/_search"), 
		A<string>.That.Contains("value\": \"searchTerm"))).
	Returns(value);

var client = new ElasticClient(settings, connection);
	
var items = client.Search<ElasticSearchProject>(s => 
	s.Index("nest_test_data")
	.Query(
		q => q.Term(f => f.Name, "searchTerm"))
);

Assert.That(items.Documents.Count(),Is.EqualTo(10));
