There is an apparent typo in setUpPage function that makes failing tests look as if they passed:

function setUpPage() {
   setUpPageStatus = 'running';
...
       if (docsLoaded == <xsl:value-of select="count($loads)"/>) {
          setUpPage = 'complete'; <-- HERE
       }
    } catch(ex) {
        catchInitializationError(builder, ex);
        setUpPage = 'complete'; <-- HERE
    }

In the two cases above, setUpPage should be replaced with setUpPageStatus.
