[Webtest] Webtest does not pick values from excel

[Aparna Shankar]

Hi,

I have a webtest that I am trying to iteratively run for the data in the
excel file. Strangely I am not able to get the values from the excel
anywhere inside the webtest tag.

<dataDriven tableContainer="simple.xls">
<webtest name="Login ${Username} ${Password}">
 <echo message="Hello  ${Username} ${Password}"/>
...

</webtest>
</dataDriven>

I can print the value of the username and password in the webtest name .
 But the echo does not print the value, instead prints "Hello  ${Username}
${Password}"

Has anybody seen this happening?
Any help is appreciated.

Thanks
