NUnit的[TestCaseSource]具有多个参数，例如MbUnit的[工厂]

Question

是否可以将NUnit的[TestCaseSource]属性与多个参数一起使用？这是我的代码（正在从MbUnit迁移）：

public IEnumerable<object[]> GetTestSwitchMultiItems()
{
    yield return new object[] { SwitchType.Sell, 0.94733, 
                       new SwitchSourceItem[] { new SwitchSourceItem(1176, 100, 50, SwitchSourceItem.QuantityType.TotalQuantity, SwitchType.Sell)}, 
                       new SwitchEquivalentItem[] { new SwitchEquivalentItem(415318955, 35, 25, SwitchType.Buy), new SwitchEquivalentItem(4348, 65, 45, SwitchType.Buy) } };
    yield return new object[] { SwitchType.Sell, 0.94733, 
                       new SwitchSourceItem[] { new SwitchSourceItem(1176, 100, 50, SwitchSourceItem.QuantityType.TotalQuantity, SwitchType.Sell)}, 
                       new SwitchEquivalentItem[] { new SwitchEquivalentItem(415318955, 15, 25, SwitchType.Buy), new SwitchEquivalentItem(4348, 25, 45, SwitchType.Buy), 
                                                    new SwitchEquivalentItem(430397879, 20, 15, SwitchType.Buy), new SwitchEquivalentItem(5330, 20, 85, SwitchType.Buy)} };
}
[Test, TestCaseSource("GetTestSwitchMultiItems")]
public void TestSwitchMultiItems(SwitchType switchType, double exchangeRate, SwitchSourceItem[] sources, SwitchEquivalentItem[] equivs)
{
    ...
}

您可以看到，参数是作为对象[]传递的，以便在TestSwitchMultiItems中有多个参数。这应该有效吗？我必须在TestSwitchMultiItems中只使用一个参数（object[]parameters）。非常感谢。

是的，可以将TestCaseSource属性与多个参数一起使用。在您给出的示例中，您将看到测试TestSwitchMultiItems运行两次。我在以下设计的测试代码中使用了NUnit。TestSwitchMultiItems运行两次，每次测试中琐碎的Assert调用都通过。

[Test, TestCaseSource("GetTestSwitchMultiItems")]
public void TestSwitchMultiItems(string switchType, double exchangeRate, object[] sources, object[] equivs)
{
   Assert.AreEqual("Sell", switchType);
}
public IEnumerable<object[]> GetTestSwitchMultiItems()
{
    yield return
       new object[]
       {
          "Sell", 0.94733, new object[] { new { a = 1176, b = 100, c = 50, d = 5, e = "Sell" } },
            new object[] { new { a = 415318955, b = 35, c = 25, d = "Buy", e = 4348, f = 65, g = 45, h = "Buy" } }
        };
    yield return
        new object[]
        {
           "Sell", 0.94733, new object[] { new { a = 1176, b = 100, c = 50, d = 5, e = "Sell" } },
            new object[]
            {
                new { a = 415318955, b = 35, c = 25, d = "Buy", e = 4348, f = 65, g = 45, h = "Buy" },
                new { a = 415318955, b = 35, c = 25, d = "Sell", e = 7348, f = 65, g = 45, h = "Sell" }
            }
        };
}
