Dear WebTest community, We're trying to upgrade to the latest version of Canoo WebTest, which appears to still be 1812, and we already had issues with it that we were working on. But tests that were passing fine using WebTest 1812 are now failing since the upgrade of Dojo. I asked my teammate Mike to write up the problem, since I can't explain it properly myself. I can add, though, that disabling JS in the WebTest is not a good option with this newest version of Dojo, because most of our buttons have JS, and they won't work without it, so we can't work around this issue with disabling JS.
If there is no way to get around this in Canoo WebTest, I guess our only option is to move to another test framework, which will take us a long time, as we have 8 years' worth (and many thousands of test cases) of WebTest scripts which, up to now, have provided us a lot of value in regression test coverage. I've been worried about WebTest since it hasn't been updated much the past year or two. Is it dying out? thanks, Lisa ------ Forwarded Message *From: *Mike Thomas <[email protected]> *Date: *Mon, 9 Apr 2012 14:54:38 -0600 *To: *Lisa Crispin <[email protected]> *Subject: *Issues with Dojo Canoo and using a CDN Our application depends on the Dojo toolkit for a number of features. WebTest has never supported Dojo properly, but to date we've been able to limp along by using workarounds to avoid major issues (for example, we sometimes turn off JavaScript on certain tests to avoid Dojo/Canoo issues (that is, if it doesn't cause other issues to do so). We are attempting to convert our application so that it loads the Dojo Toolkit from a CDN rather than from local sources. We switched from: <script type="text/javascript" src="/include/javascript/dojotoolkit/dojo/dojo.js"></script> to <script src=" https://ajax.googleapis.com/ajax/libs/dojo/1.7.2/dojo/dojo.js"; djConfig="parseOnLoad: true"></script> This makes management and upgrades much simpler for us. However, it also causes every WebTest test in our system to fail with a JavaScript error since we include Dojo on every page, whether we use it or not (it's a framework thing): JavaScript error loading page http://localhost:8080/home/index.jsp?&fid=2: Wrapped com.gargoylesoftware.htmlunit.ScriptException: Wrapped com.gargoylesoftware.htmlunit.ScriptException: TypeError: Cannot read property "firstChild" from undefined ( https://ajax.googleapis.com/ajax/libs/dojo/1.7.2/dojo//parser.js#8) Our pages work properly in browsers. Our current version is 1762. We realize that is an older version, so we're trying to upgrade. However, the upgrade (1812) fails differently. Aside from some unrelated issues, tests were running fine with the latest WebTest release, but when test are run agains the CDN-enabled version of our system we get a different failure. This seems only to happen on pages that actually USE Dojo, as opposed to version 1762 where any test of a page that imported Dojo would fail. javascript error Wrapped com.gargoylesoftware.htmlunit.ScriptException: Wrapped com.gargoylesoftware.htmlunit.ScriptException: Wrapped com.gargoylesoftware.htmlunit.ScriptException: Wrapped com.gargoylesoftware.htmlunit.ScriptException: Wrapped com.gargoylesoftware.htmlunit.ScriptException: Wrapped com.gargoylesoftware.htmlunit.ScriptException: Wrapped com.gargoylesoftware.htmlunit.ScriptException: TypeError: Cannot read property "value" from null ( https://ajax.googleapis.com/ajax/libs/dojo/1.7.2/dojo//parser.js#8) line 0 javascript source function (evt) { evt = evt || _3b7.event; if (_3ba || (evt.type == "readystatechange" && !_3b8[doc.readyState])) { return; } _3ba = 1; if (_3b9) { doc.readyState = "complete"; } while (_3bb.length) { (_3bb.shift())(); } } failing line javascript call stack Wrapped com.gargoylesoftware.htmlunit.ScriptException: Wrapped com.gargoylesoftware.htmlunit.ScriptException: Wrapped com.gargoylesoftware.htmlunit.ScriptException: Wrapped com.gargoylesoftware.htmlunit.ScriptException: Wrapped com.gargoylesoftware.htmlunit.ScriptException: Wrapped com.gargoylesoftware.htmlunit.ScriptException: Wrapped com.gargoylesoftware.htmlunit.ScriptException: TypeError: Cannot read property "value" from null ( https://ajax.googleapis.com/ajax/libs/dojo/1.7.2/dojo//parser.js#8) In the past, when we're run into oddbal Dojo errors in WebTest, we've disabled JavaScript. However, this is becoming more and more impractical since many pages do at least a bit of simple Javascript to get things done. So, if we don't upgrade, we can't convert to a CDN because the Dojo import fails to work. If we do upgrade we can't convert to a CDN because we get random errors in dojo.js if a page uses Dojo. ------------------------------------------------- *Mike Thomas *Lead Architect, Engineering ePlan Services, Inc [email protected] 303-567-8936 ------------------------------------------------- ------ End of Forwarded Message -- Lisa Crispin Co-author with Janet Gregory, _Agile Testing: A Practical Guide for Testers and Agile Teams_ (Addison-Wesley 2009) Contributor to _Beautiful Testing_ (O'Reilly 2009) http://lisacrispin.com @lisacrispin on Twitter http://entaggle.com/lisacrispin
