Selenium IDE always returns "true" on XPath evaluation

Question

I am working on a test in the Selenium IDE, which (among other things) looks at login.microsoftonline.com to check if a particular username is listed in the accounts that have authenticated before (from a particular browser, on a particular PC).

I am trying to evaluate for the desired username with:

return document.evaluate("//*[@data-test-id='correctusername@domain.com']", document) !== null

But it doesn't matter what I put in as the string, the variable is always set to "true".

The element I am looking at is:

<div class="row">
    <div id="tilesHolder" class="form-group" role="list" aria-labelledby="tileError loginHeader"
        data-bind="attr: { 'data-test-asynctilesloaded': !isTileRequestPending() }" data-test-asynctilesloaded="true">
        <!-- ko foreach: { data: sessions, as: 'session' } -->
        <div class="tile-container" data-bind="component: { name: 'tile-field',
                params: {
                    serverData: svr,
                    session: session,
                    hasFocus: $index() === 0,
                    ariaDescribedBy: $index() === 0 ? 'tileError loginHeader' : null,
                    isLogoutRequest: $parent.isLogoutRequest,
                    tileIndex: $index() },
                event: {
                    tileClick: $parent.tile_onClick,
                    forgetComplete: $parent.tile_onForgetComplete } },
                css: { 'binaryChoice list': svr.fSupportWindowsStyles }"><!--  -->

We can see "data-test-id="wronguser@domain.com"" in a, which is a user who has logged-in, but not the one I care about.

How do I test for the correct username, while allowing for an if/else statement to be run on the results?

Answer 1

I think the issue is in the comparing to NULL.

Document.evaluate() returns an integer that corresponds to the type of result XPathResult to return. The following values are possible:

ANY_TYPE (0) Whatever type naturally results from the given expression.

NUMBER_TYPE (1) A result set containing a single number. Useful, for example, in an xpath expression using the count() function.

STRING_TYPE (2) A result set containing a single string.

BOOLEAN_TYPE (3) A result set containing a single boolean value. Useful, for example, an xpath expression using the not() function.

UNORDERED_NODE_ITERATOR_TYPE (4) A result set containing all the nodes matching the expression. The nodes in the result set are not necessarily in the same order they appear in the document.
