示例1: GroupBy_Spike
public void GroupBy_Spike() {
var values = new[] {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
var groups = values.GroupBy(x => x % 2 == 0);
Assert.That(groups.First().Key, Is.False);
Assert.That(groups.First(), Is.EqualTo(new[] {1, 3, 5, 7, 9}));
Assert.That(groups, Is.EqualTo(new[] { new[] { 1, 3, 5, 7, 9 }, new[] { 2, 4, 6, 8, 10 } }));
}示例2: When_starting_a_game__everyones_totems_should_be_unique
public void When_starting_a_game__everyones_totems_should_be_unique()
{
var player1Filename = TestHelper.GetSrcFilenameFrom(browser.FindCss("img#player-1"));
var player2Filename = TestHelper.GetSrcFilenameFrom(browser.FindCss("img#player-2"));
var player3Filename = TestHelper.GetSrcFilenameFrom(browser.FindCss("img#player-3"));
var player4Filename = TestHelper.GetSrcFilenameFrom(browser.FindCss("img#player-4"));
var filenames = new[] {player1Filename, player2Filename, player3Filename, player4Filename};
var numberOfUniqueFilenames = filenames.GroupBy(x => x).Count();
Assert.AreEqual(4, numberOfUniqueFilenames, "Expected unique filenames, got: " + string.Join(", ", filenames));
