Is it possible to find all visited links in the browser?

Is it possible to find all visited links in the browser?

This is the snippet from this code:
<a href='www.apple.com'>apple</a>
<a href='www.google.com'>Google</a>
__
a{
display: block;
background-color: rgba(200,200,180,0.4);
margin-bottom: 18px;
line-height: 160%;
}
a:visited{
background-color: red;
}
It applies :visited css to second hyperlink and if I change first
hyperlink from www.apple.com to http://www.apple.com it applies :visited
css to that also (strange?).
Why I am doing this is because one of the QA person says that one of the
hyperlink in my page always shows as visited while he didn't visited the
link. Even if we reset safari it still shows as visited. Unless we restart
the mac it always says visited.
Is it possible to show him the list of hyperlinks he visited. ( It is not
in browser history as well )
