我正在尝试测试一个异步进程，其中向具有不同值的服务发出多个请求，这会导致引发多个完成事件。

该应用程序是 WP7 应用程序，其中包含 WP7 类库项目中的代码和测试，所有其他测试（带有模拟）都可以正常工作，只有这个测试我无法开始工作。

测试是：

    [Test]
    public void Should_referesh_all_stocks_held_in_collection()
    {
        var fakeStockService = new Mock<IStockService>();
        var msftStock = new StockViewModel { Symbol = "MSFT", Name = "Microsoft", Price = 12.5m, Change = "+1" };

        var googStock = new StockViewModel { Symbol = "GOOG", Name = "Google", Price = 12.0m, Change = "-1" };

        var target = new StockSummaryViewModel(fakeStockService.Object);

        target.Stocks.Add(msftStock);
        target.Stocks.Add(googStock);

        fakeStockService.Setup(s => s.GetStock("MSFT"))
            .Raises(s => s.StockQuoteReceived += null, new StockQuoteEventArgs(new QuoteReceived { Symbol = "MSFT", Name = "Microsoft Corp", Last = "13.5", Change = "+1" }));

        fakeStockService.Setup(s => s.GetStock("GOOG"))
            .Raises(s => s.StockQuoteReceived += null, new StockQuoteEventArgs(new QuoteReceived { Symbol = "GOOG", Name = "Google", Last = "11.5", Change = "-0.5" }));

        target.Refresh();

        Assert.AreEqual(2, target.Stocks.Count);
        var stock = target.Stocks.Single(s => s.Symbol == "MSFT");

        Assert.IsTrue(stock.Change == "+1" && stock.Price == 13.5m);

        stock = target.Stocks.Single(s => s.Symbol == "GOOG");
        Assert.IsTrue(stock.Change == "-0.5" && stock.Price == 11.5m);
    }

测试失败，因为没有触发第二个事件，而是第一个 raise 触发了两次。

我错过了什么？
