添加[DataSource]属性后MSTest无法发现CSV数据源测试求助

我有一个MSTest单元测试，未添加[DataSource]属性时运行正常，但添加该属性以读取CSV文件后，MSTest无法发现该测试。

添加[DataSource]前的测试代码 #

[TestMethod]
[TestCategory("BVT")]
public void GetLotsByBillingAccount()
{
    string requestUrl = string.Empty;

    if (!string.IsNullOrEmpty(BillingProfileId))
        requestUrl = string.Format(TestConstants.URL_Lots, CCMEndpoint, BillingAccountId, BillingProfileId);
    else if (!string.IsNullOrEmpty(Source) && !string.IsNullOrEmpty(Status))
        requestUrl = string.Format(TestConstants.URL_LotsByBillingAccountWithFilters, CCMEndpoint, BillingAccountId, Status, Source);
    else
        requestUrl = string.Format(TestConstants.URL_LotsByBillingAccount, CCMEndpoint, BillingAccountId);

    var result = TestHelper.ProcessRequest(requestUrl, PrincipalId, null, DefaultCertificate, TenantId, ObjectId, accessToken: GtmAccessToken, armSignedToken: GtmAccessToken);
}

添加的[DataSource]属性 #

添加以下属性后测试不再被发现：

[DataSource("Microsoft.VisualStudio.TestTools.DataSource.CSV", 
            @"|DataDirectory|\Data\ProdLotsInput.csv", 
            "ProdLotsInput#csv", 
            DataAccessMethod.Sequential)]

SDK风格项目文件（已从旧项目风格迁移） #

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <OutputType>Library</OutputType>
    <AppDesignerFolder>Properties</AppDesignerFolder>

  <ItemGroup>
    <None Include="Data\ProdLotsInput.csv">
      <CopyToOutputDirectory>Always</CopyToOutputDirectory>
    </None>
  </ItemGroup>
</Project>

测试输出日志（视图->输出->测试） #

已尝试的解决步骤 #

• 确认CSV文件路径正确（|DataDirectory|\Data\ProdLotsInput.csv）
• 验证CSV文件的生成操作设置为Content，复制到输出目录设置为“较新则复制”
• 尝试用CSV文件的绝对路径替代|DataDirectory|
• 向测试类添加TestContext属性

以上尝试均未解决问题，请问添加[DataSource]属性后，是什么原因导致MSTest无法发现测试？恳请提供帮助或建议！
