hasAnyText should trim white space?

[simonihmig]

hasAnyText returns true even if textContentcontains only white space (spaces and/or line breaks). Is this expected?

For something like this:

<p data-test-message>
{{#if this.showMessage}}
  {{this.message}}
{{/if}}
</p>

assert.dom('[data-test-message]').hasAnyText() would always return true!

hmm... I guess in that case the whitespace collapsing would collapse it down to a single whitespace, but the content would still be ' ', not ''. so I guess maybe that is indeed correct? 😅

the whitespace collapsing would collapse it down to a single whitespace

Why that?

[simonihmig]

And however it is implemented, the question is how it is designed? Shouldn't a whitespace-only string be considered "empty", at least in the context of hasAnyText? See my real world example above...

it's using https://github.com/simplabs/qunit-dom/blob/master/lib/helpers/collapse-whitespace.ts, though I don't remember exactly where I've found the rules for that algorithm 😅

it is meant to somewhat resemble https://developer.mozilla.org/en-US/docs/Web/API/Document_Object_Model/Whitespace
