[Edbrowse-dev] test #0

[Kevin Carhart <kevin@carhart.net>]

Thanks Karl.  I'm putting it on list because I hope everyone will have 
some remarks.  Adam, you brough up the acidtests in the first place but I 
haven't talked to you about it much lately.

This is going to be lovely and hospitable JS in some ways, 
in the same vein as observing that the author called a variable 
kungfuDeathGrip - goofy, capricious, but at least we know that this is 
javascript written by human beings, intended to be read, with comments, 
linefeeds, and carved up into small pieces!

So here's the code for test zero.

Note: the assertEquals function is referenced but I didn't copy it in 
also.  So that could be a problem for understanding the test, but you 
can probably tell from context what assertEquals does.  It's a utility 
called at the end of a test, to assert that two things should be equal 
and pass or fail based on whether they are.


function () {
       // test 0: whether removing an element that is the last child 
correctly recomputes styles for the new last child
       // also tests support for getComputedStyle, :last-child, pre-wrap, 
removing a <script> element
       // removing script:
       var scripts = document.getElementsByTagName('script');
       document.body.removeChild(scripts[scripts.length-1]);
       // removing last child:
       var last = document.getElementById('remove-last-child-test');
       var penultimate = last.previousSibling; // this should be the 
whitespace node
       penultimate = penultimate.previousSibling; // this should now be the 
actual penultimate element
       last.parentNode.removeChild(last);
       assertEquals(document.defaultView.getComputedStyle(penultimate, 
'').whiteSpace, 'pre-wrap', "found unexpected computed style");
       return 7;
     },
