<p>Question:
<em>I was trying to write a simple script that does a google search.
I have been running into all sorts of problems. Does this work for you?
Here is my test:</em> <table cellpadding="1" cellspacing="1" border="1">
<tbody>
<tr>
<td rowspan="1" colspan="3">Test Type<br>
</td>
</tr>
<tr>
<td>open</td>
<td>http://www.google.com/</td>
<td> </td>
</tr>
<tr>
<td>type</td>
<td>q</td>
<td>testing tools</td>
</tr>
<tr>
<td>click</td>
<td>submitButton</td>
<td> </td>
</tr>
</tbody>
</table>.</p>
<p>Answer:
The quick answer is that because of cross-site scripting security built into
JavaScript engines in all browsers, you can't edit the content of a web page
from another domain. The foreign page will probably load correctly and be visible
in the test runner window, but Selenium won't be able to query or edit its contents.
In other words, you can't run selenium on "foo.com" and
run a test that edits values and clicks buttons against "bar.com". So, in
its current form, you can't "script" google.com because your script isn't
currently hosted on google.com. When Selenium and the application you are
testing is hosted on the same domain, however, you do not run into the
cross-site scripting security feature/limitation.</p>
<p>You read more about cross-site scripting here: <a class="reference" href="http://www.devarticles.com/c/a/JavaScript/JavaScript-Security/">http://www.devarticles.com/c/a/JavaScript/JavaScript-Security/</a></p>
<p>Also, if cross-site scripting security didn't exist, be careful about your
field and button references in your tests. The current version
of Selenium uses the "id" attribute of the object you are referring to in your
test. The search field and submit button at google.com have "name" attributes,
but not not "id" attributes. Therefore, Selenium wouldn't be able to find the objects.
Future versions of Selenium will be able to search for objects by more than
just the id attribute, though.</p>

<h2><a class="toc-backref" href="#id5" name="how-can-i-run-my-test-against-a-foreign-or-remote-server-and-get-around-cross-site-scripting-security">1.3 How can I run my test against a foreign or remote server and get around cross-site scripting security?</a></h2>
<p>There are a few ways around cross-site scripting to access a remote server.
You could use a combination of proxying and URL rewriting in Apache to
trick the browser into the thinking the application and the testing tool
are coming from the same domain.</p>
<p>Another option is to run Selenium as an "HTA" application, or "HTML
Application" in Internet Explorer. HTA applications run in the security
context of any trusted application on the client, so there is no cross-site
scripting limitation. (You can find out more here:
<a class="reference" href="http://msdn.microsoft.com/workshop/author/hta/overview/htaoverview.asp">http://msdn.microsoft.com/workshop/author/hta/overview/htaoverview.asp</a>) The
equivalent to this "security-free" client on the Mozilla side of the fence
would be to write a XUL wrapper/extension.</p>
<p>Also, please see the answer to the related question: "Why can't I script google.com".</p>

<h2><a class="toc-backref" href="#id6" name="how-do-you-create-test-tables">1.4 How do you create test tables?</a></h2>
<p>The developers on the Selenium project use Mozilla Composer to
create plain HTML text files for their tests.
By default, Mozilla Composer writes very clean HTML without any extra, unnecessary markup.</p>
<p>Future versions of Selenium may support RST (ReStructred Text), or wiki-table
syntax, natively. However, you are free to use another format now,
as long as you remember to generate the HTML files from your source files,
either during your build process or dynamically at run-time.</p>
