I am seeing different (possibly related) anomalies when I attempt to use various web browsers to run the Jubula example SimpleAdderHTML tests and would appreciate any information on how to resolve them. The issues occur when I start and stop a Chrome AUT or an Internet Explorer AUT from the Jubula ITE. My colleague is observing the same behaviors with Chrome and IE and similar issues with a Firefox AUT. I have not been able to find any mention of these issues in the Jubula forum.
Has anyone experienced anything similar to the behavior described below? Are there any actions I can take to correct the issues?
The issues are:
1. Starting the AUT from Jubula - Each browser (Chrome, IE, Firefox) exhibits different problems on startup.
2. Stopping the AUT from Jubula - Although all browsers can be shut down from Jubula, a NullPointerException is recorded in the Jubula log.
I am using Jubula 8.2.0.021 in a Windows 7 environment with Java 8, IE version 11, and Chrome version 48. My colleague's environment is the same configuration. I created a Jubula project, imported the Samples_8.2 and bound_modules_samples_8.2 projects, and made no changes to the project other than to create separate AUT configurations for Chrome and IE. I use the Jubula Embedded AUT Agent.
I am able to start the Chrome browser instance from the Jubula ITE and successfully run the example tests, however, I am not able to start the IE browser without errors. I have attached images that show screen images of both Chrome and IE.
Starting AUTs
Chrome
The Chrome AUT starts and I can run the SimpleAdderHTML tests, however the following entry appears in the rc_html.log when the Chrome AUT starts:
2016-02-12 16:21:08.717 [SocketListener0-1] WARN org.openqa.selenium.net.Urls - It looks like your baseUrl (http://www.eclipse.org/jubula/example/auts/adder/SimpleAdder.html) is pointing to a file, not a directory (it doesn't end with a /). We're going to have to strip off the last part of the pathname.
The Chrome browser's address field displays the following URL when Chrome starts:
http://www.eclipse.org/selenium-server/core/RemoteRunner.html?sessionId=38b22e17a8cc493b9061b009abf6240a&multiWindow=false&baseUrl=http%3A%2F%2Fwww.eclipse.org%2Fjubula%2Fexample%2Fauts%2Fadder%2FSimpleAdder.html&debugMode=false
Chrome has an additional issue at startup that I suspect has something to do with Jubula's interaction with Selenium. Chrome reports a problem with a command-line flag ("--disable-web-security"), but handles the issue well by simply displaying a warning message. (See the attached "Chrome AUT Startup" image file.)
Is there a way to configure Jubula/Selenium and remove that command-line flag?
One additional fact that is likely related to the disable-web-security Chrome command-line flag is that some web sites do not render in the Chrome browser. For example, the SimpleAdderHTML and www.amazon.com web pages both display properly. However, if I set the AUT configuration's AUT URL to be www.google.com or www.airtable.com, the browser fails to display the web site and reports an ERR_INSECURE_RESPONSE error. (See the attached "Chrome Insecure Response Error for Google Web Site" image file.) The SimpleAdderHTML web page uses HTML 4.01 Tranisitional, whereas the other three web sites use HTML 5, but I don't think that this difference has any bearing on the problem.
Internet Explorer
When the IE AUT starts, Jubula logs the same warning in the rc_html.log, however IE does not handle the issue well at all. The log entry for IE is:
2016-02-12 16:32:09.480 [SocketListener0-1] WARN org.openqa.selenium.net.Urls - It looks like your baseUrl (http://www.eclipse.org/jubula/example/auts/adder/SimpleAdder.html) is pointing to a file, not a directory (it doesn't end with a /). We're going to have to strip off the last part of the pathname.
When the IE AUT starts, the browser window tries to display content in a single frame and fails. In Jubula's Running AUTs view, the running IE AUT configuration appears, but the HTML tests fail immediately when I try to run them. (See the attached "Internet Explorer AUT Startup" image file.)
Firefox
When the Firefox AUT starts, it displays an HTTP 404 File Not Found error. I don't have any more details for this issue, but can provide them if needed, although I suspect that Firefox is just exhibiting different behavior for the same issue as describe above for Chrome and IE.
Stopping AUTs
Chrome
This may be unrelated to the above issues, but when I select the running Chrome AUT in the Jubula Running AUTs tab and click on the Stop AUT button, the Chrome browser instance appears to shut down properly and the Jubula GUI does not report an errors, but the following entry appears in the rc_html.log:

Internet Explorer
When I perform the same Stop AUT to shutdown the IE browser, the browser shuts down with no apparent errors, like the Chrome browser, but the following entries appear in the rc_html.log:
2016-02-12 16:34:23.136 [SocketListener0-2] WARN o.o.s.s.b.HTABrowserLauncher - Embedded iexplore seems to have ended on its own (did we kill the real browser???)
