你能构建你自己的MSTEST DataSource吗？

public class CsvDataSource : ITestDataSource
{
    private string _filePath;

    public CsvDataSource(string filePath)
    {
        _filePath = filePath;
    }

    public IEnumerable<object[]> GetTestData()
    {
        var testData = new List<object[]>();

        using (var reader = new StreamReader(_filePath))
        {
            string headerLine = reader.ReadLine();
            if (headerLine != null)
            {
                string[] headers = headerLine.Split(',');
                string line;
                while ((line = reader.ReadLine()) != null)

                    string[] values = line.Split(',');

                        dataRow[i] = Convert.ChangeType(values[i], headers[i].GetType());
                    }

[TestClass]
public class MyTestClass
{
    [TestMethod]
    [DataSource(typeof(CsvDataSource), "test_data.csv")]
    public void MyTestMethod(string param1, int param2)
    {
        // 测试逻辑
        Assert.IsTrue(param2 > 0);
    }
