The connection string for coded UI Data driven test using excel data source is not working

Question

Hello,
I am using the visual studio 2012 coded UI test, i added the following connection strings to connect to an excel data source:
[DataSource("System.Data.Odbc", "Dsn=Excel Files;Driver={Microsoft Excel Driver (*.xls)};dbq=C:\\Users\\shaza.said.ITWORX\\Desktop\\Automation\\On-track Automation Framework\\On-track_Automation\\Automation data file.xls;defaultdir=.;driverid=790;maxbuffersize=2048;pagetimeout=5;readonly=true",
"Sheet1$", DataAccessMethod.Sequential), TestMethod]
[DataSource("System.Data.Odbc", "Dsn=Excel Files;dbq=|DataDirectory|\\Automation data file.xls;defaultdir=C:\\Users\\shaza.said.ITWORX\\Desktop\\Automation\\On-track Automation Framework\\On-track_Automation\\Automation data file.xls;driverid=1046;maxbuffersize=2048;pagetimeout=5",
"Sheet1$", DataAccessMethod.Sequential), TestMethod]
But i get the following error:
"The unit test adapter failed to connect to the data source or to read the data. For more information on troubleshooting this error, see "Troubleshooting Data-Driven Unit Tests" (http://go.microsoft.com/fwlink/?LinkId=62412) in the MSDN Library.
Error details: ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified"
Thanks,

Thanks for Adrian's help.
Hi shaza,
From the error message, I suggest you can refer the Adrian's suggestion to check the date source connection string correctly.
In addition, you can refer the following about how to Create a Data-Driven Coded UI Test to check your issue:
http://msdn.microsoft.com/en-us/library/ee624082.aspx
Or you can also try to use a Configuration File to Define a Data Source for coded UI test.
For example:
<?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="ExcelConn"
connectionString="Dsn=Excel Files;dbq=E:\Unit Test\AddClass\AddUnitTest\add.xlsx;defaultdir=.;
driverid=790; maxbuffersize=2048; pagetimeout=60;"
providerName="System.Data.Odbc"/>
<add
name="ExcelConn1"
connectionString="Dsn=Excel Files;dbq=E:\Unit Test\AddClass\AddUnitTest\sum.xlsx;defaultdir=.;
driverid=790;maxbuffersize=2048;pagetimeout=60"
providerName="System.Data.Odbc"/>
</connectionStrings>
<microsoft.visualstudio.testtools>
<dataSources>
<add
name="ExcelDS_Addition"
connectionString="ExcelConn"
dataTableName="Addition$"
dataAccessMethod="Sequential"/>
<add
name="ExcelDS_Multiply"
connectionString="ExcelConn1"
dataTableName="Multiply$"
dataAccessMethod="Sequential"/>
</dataSources>
</microsoft.visualstudio.testtools>
</configuration>
