用于测试 ArrayList 对象的 NUnit 测试用例

Question

我有一个方法可以检索 DataTable 并迭代每个 DataRow 并存储每一行 在 ArrayList 中。迭代结束后，它返回 ArrayList。我如何编写测试用例来测试 ArrayList ？

示例：

ArrayList =>0 ( {1,personName1,Designation} );

ArrayList =>1 ( {2,personName2,Designation} );

ArrayList => 2 ( {3,personName3,Designation} );

提前致谢。

也许像下面这样：

[Test]
public void RetrieveDataTableAndArrayList()
{
    // set up dependencies here
    // i.e. maybe a mocked DataSet which would return your DataTable?

    // an instance of the class under test
    var sut = new SystemUnderTest(dataSet); 

     // the method that you are testing
    ArrayList result = sut.RetrieveDataTable();

    // verification of results
    DataRow row1 = (DataRow)result[0];
    Assert.AreEqual(1, row1.Field<int>(0));
    Assert.AreEqual("personName1", row1.Field<string>(1));
    Assert.AreEqual("Designation", row1.Field<string>(2));
    // ... and so on
}
