TestSelector does not understand MSTestV2 DataRow attribute

[Mertsch]

Environment

• Server - VSTS
• Agent - Private

  Issue Description

  I have the following Test

  [TestMethod]
  [DataRow("CN=TestFirst\\, AndLastName", "TestFirst, AndLastName (Full Control, SID=S-1-88-1)")]
  [DataRow("TestName", "TestName (Full Control, SID=S-1-88-1)")]
  [DataRow(null, " (Full Control, SID=S-1-88-1)")]
  public void DisplayNameTest(string input, string expected)
  {
  // Code
  }

  TIA does not realise that this is one specific test case with parameters and will always run this test, even if not impacted, see log files below.

@Mertsch this is a known issue in TIA today. Check https://blogs.msdn.microsoft.com/devops/2017/03/02/accelerated-continuous-testing-with-test-impact-analysis-part-1/ for known issues. TIA today always run data driven test cases in TIA mode.
