Description Philippe Mouawad 2019-05-21 13:00:30 UTC 
If you have this response:

<response>
 <code>1</code>
 <error>Print Error</error>
 <error>Network Error</error>
</response>

With:

- XPath: count(//*[code=1])=1
- True if nothing matches checked


The expected result would be to have the Assertion fails as the XPath result is true.

 
The result you get is that there is no difference wether you check or not True if nothing matches checked and assertion succeeds.

There are in fact 2 issues:

- True if nothing matches checked is confusing, and should be named "Invert assertion" as that's what one is expecting
- Since the boolean function returns a node (True /False), True if nothing matches checked will always succeed
