Support of variables for measure attribute

[lukzas]

I have two scenarios where it would be handy to have variable support:

1. I'd like to user variable inside the expression

<expression name="TotalPriceWithVAT">UnitPrice*Quantity*@MultiplyFactor</variable>

2. When using <instance-settling>

<system-under-test>
      <structure>
        <measure caption="@Caption" perspective="@Perspective"/>
      </structure>
</system-under-test>

3. Is instance variable scope limited to <system-under-test>? It seems I can't use a variable as below

<assert>
        <equal-to>
          <query>
            <parameter name="@table">@Table</parameter>
              SELECT * FROM @table
          </query>
        </equal-to>
</assert>

Maybe it is already possible and I don't know how to configure, in case it's not let me know your thoughts. I guess the latter might be a rough one 😉

I’ll need to double-check but it should not be a big issue to support variables in NCalc expressions. Will try to add it for next release.

About using variables in an assertion, it is already globally supported. But something that could be potentially not supported is to use a variable for a specific element or attribute. Could you post your test and highlight which element or attribute has an issue. I know that the comparison of result-sets have a good support for variables but not assertions on structures.

For the third case, I’d try to switch to equal-to\result-set\query in place of equal-to\\query. Using the canonical form could help.

<test name="Measure Exist">
    <instance-settling>
      <local-variable name="PerspectiveName" type="text">
          <item>Claims</item>
          <item>Assessors</item>
      </local-variable>
    </instance-settling>
    <system-under-test>
      <structure>
        <!-- variable is not evaluated in this context -->
        <measure caption="Additional Report" perspective="@PerspectiveName"/> 
      </structure>
    </system-under-test>
    <assert>
      <exists />
    </assert>
</test>

I opened #567 and #568 to differentiate the issues/feature-requests reported.
