How to check if a string variable is empty?

[Mark Phillips]

Hi All
I have a string parameter defined as follows:

<Parameter Name="AllowedQueues" Type="String" Parent="Call Reporting" Editor="String" Title="Journal calls handled by these queues" />

I am trying to test for it being empty in an scenario's SkipIf:

<Request SkipIf="[[AllowedQueues].Equals(&quot;&quot;)]==True"

I have also tried:

<Request SkipIf="[AllowedQueues]==&quot;&quot;

And other variations, none of which cause the scenario to be skipped when [AllowedQueues] doesn't contain any data.

However,

<Request SkipIf="[[AllowedQueues].Equals(&quot;ABC&quot;)]==True"

and

<Request SkipIf="[AllowedQueues]==&quot;ABC&quot;

works fine when [AllowedQueues] contains the string ABC.

Any ideas?
Thanks
Mark

I would use 0 as "none" and use the ==0 SkipIf value.

Just guessing here, but maybe the parameter is null instead of an empty string, and that's why the comparison against an empty string is false. Can you try adding an empty string as default value for the parameter?
<Parameter Name="AllowedQueues" Type="String" Parent="Call Reporting" Editor="String" Title="Journal calls handled by these queues" Default="" />
