Upgraded to MSTest v2, The type initializer for 'Microsoft.VisualStudio.TestTools.UnitTesting.TestConfiguration' threw an exception

See original GitHub issue

Question

Has anything changed around the DataSource attribute in MSTest v2? Were there any upgrade steps I need to perform?

Description

Have upgraded to MS Test v2 (v 1.1.13). Running my unit test gives:

Message: The type initializer for 'Microsoft.VisualStudio.TestTools.UnitTesting.TestConfiguration' threw an exception.

Result StackTrace:	
at Microsoft.VisualStudio.TestPlatform.MSTestAdapter.PlatformServices.TestDataSource.GetConnectionProperties(DataSourceAttribute dataSourceAttribute, String& providerNameInvariant, String& connectionString, String& tableName, DataAccessMethod& dataAccessMethod)
   at Microsoft.VisualStudio.TestPlatform.MSTestAdapter.PlatformServices.TestDataSource.RunDataDrivenTest(TestContext testContext, ITestMethod testMethodInfo, ITestMethod testMethod, TestMethodAttribute executor)

Steps to reproduce

I have the following attributes on my test:

    [TestMethod]
    [DataSource("NoteData")]
    [DeploymentItem(@".\TestFiles\ExcelFiles\TestData.xls")]
    [DeploymentItem(@".\TestFiles\Note", "NoteAck")]
    [DeploymentItem(@".\TestFiles\Note", @"TestFiles\NoteAck")]

In my app.config I have


 <microsoft.visualstudio.testtools>
    <dataSources>
      <add name="NoteData" connectionString="TestDataConnection" dataTableName="IssueNoteAck$" dataAccessMethod="Sequential" />
    </dataSources>
  </microsoft.visualstudio.testtools>

<connectionStrings>    
    <add name="TestDataConnection" connectionString="Driver={Microsoft Excel Driver (*.xls)}; dbq=TestData.xls; defaultdir=.; driverid=790; maxbuffersize=2048; pagetimeout=5; readonly=true;" providerName="System.Data.Odbc" />
  </connectionStrings>

Expected behavior

Test would pass as previously

Actual behavior

As above with exception and stack trace

Environment

Actually, I seem to have found the fix! The issue was the old configSections declaration at the top of the app.config. I found that changing the previous one from <section name="microsoft.visualstudio.testtools" type="Microsoft.VisualStudio.TestTools.UnitTesting.TestConfigurationSection, Microsoft.VisualStudio.QualityTools.UnitTestFramework, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/> to <section name="microsoft.visualstudio.qualitytools" type="Microsoft.VisualStudio.TestTools.UnitTesting.TestConfigurationSection, Microsoft.VisualStudio.TestPlatform.TestFramework.Extensions"/> and switching the <microsoft.visualstudio.testtools> around the dataSources to <microsoft.visualstudio.qualitytools> makes everything work again!

Of course!

We went from this

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <configSections>
    <section name="microsoft.visualstudio.testtools" type="Microsoft.VisualStudio.TestTools.UnitTesting.TestConfigurationSection, Microsoft.VisualStudio.QualityTools.UnitTestFramework, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
  </configSections>
  <connectionStrings>
    <add name="UnitTestConnection" connectionString="AConnectionString" providerName="System.Data.SqlClient" />
  </connectionStrings>
  <microsoft.visualstudio.testtools>
    <dataSources>
      <add name="TestDataSource" connectionString="UnitTestConnection" dataTableName="UnitTestTable" dataAccessMethod="Sequential" />
    </dataSources>
  </microsoft.visualstudio.testtools>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />
  </startup>
</configuration>

to this

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <configSections>
    <section name="microsoft.visualstudio.qualitytools" type="Microsoft.VisualStudio.TestTools.UnitTesting.TestConfigurationSection, Microsoft.VisualStudio.TestPlatform.TestFramework.Extensions" />
  </configSections>
  <connectionStrings>
    <add name="UnitTestConnection" connectionString="AConnectionString" providerName="System.Data.SqlClient" />
  </connectionStrings>
  <microsoft.visualstudio.qualitytools>
    <dataSources>
      <add name="TestDataSource" connectionString="UnitTestConnection" dataTableName="UnitTestTable" dataAccessMethod="Sequential" />
    </dataSources>
  </microsoft.visualstudio.qualitytools>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />
  </startup>
</configuration>

I actually can’t remember where I found microsoft.visualstudio.qualitytools, I think it was somewhere in this repo actually! Edit: forgot to mention that this was with 1.1.8.
