Override variables' value within the config file

[Seddryck]

From times to times, it's convenient to be able to enforce the value of a variable. It should be possible to do it in the config file to avoid to have to change the test-suite. You could be able to add the following lines:

<nbi ...>
   <variables>
      <add name="myDate" value="2013-12-01" type="DateTime"/>
      <add name="myNum" value="187" type="Numeric"/>
   </variables>
</nbi>

Even if the variable myDate is dynamically defined in the test-suite the value provided in the config will override the calculated value.
