'Page Should Contain Button' & 'Click Button' can not find HTML button

[Tset-Noitamotua]

HTML button:

<button class="foo" type="bar" data-ember-action="123">
     <i class="icon-arrow-right"></i>
    Logout
</button>

Accessing this button from RF with the following code does not work:

***keywords***
Log Off And Close Browser
    Page Should Contain Button    Logout
    Click Button                  Logout
    Login Page Should Be Open
    Close Browser

I´m quite sure that the keyword worked properly before the devs added <i class="icon-arrow-right"></i> to the button.

Here´s the output of Robot log file: Page Should Contain Button | Logout

DEBUG POST http://sut_ip/hub/session/123/elements {"using": "xpath", "sessionId": "123", "value": "//input[(@id='Logout' or @name='Logout' or @value='Logout' or @src='Logout' or @src='https://sut_url/Logout')]"}

BTW: Here I wonder why the keyword 'Page Should Contain Button' looks up in <input> tag?

DEBUG POST http://sut_ip/hub/session/123/elements {"using": "xpath", "sessionId": "123", "value": "//button[(@id='Logout' or @name='Logout' or @value='Logout' or normalize-space(descendant-or-self::text())='Logout')]"}

Click Button | Logout

I cross checked it in pure Selenium. This were my findings:

Is it possible that normalize-space() somehow breaks the keyword(s)?

You have found at least two possible issues.

1. The Page Should Contain Button and Click Button don't use internally same xpath selector to find the button. This explains many complaints in the user group mailing list.
2. normalize-space() should not break anything and I use it a lot in my own testing. But I have not used exactly that syntax, so we need to verify why that syntax did not work.

Thanks from detailed analysis.

As a workaround you can use the Page Should Contain Element and Click Element keywords.

This element does not have a locator to identify it.

If you want to use this keywords this button needs to have an id or name to works. Example: locator by id: ...button id="Logout" class="foo" type="bar" data-ember-action="123"...

locator by name: ...button name="Logout" class="foo" type="bar" data-ember-action="123"...
