Hi Ketan

I tried to execute a swtbot test using "headless" option on an exported Eclipse application. But, it fails to start the test application with "Application error" message. Following are the logs:

but, it fails to start the application. Am I missing some required plugin or we have to make some changes in the test application itself?

Looking at the stacktrace indicates that the application corresponding
to -testApplication is not found. I've fixed the error messages to
provide more information on what went wrong instead of a stacktrace like
the one you just saw.

Please see http://wiki.eclipse.org/SWTBot/Troubleshooting if you're
unable to run eclipse with the following args

-application com.your.application.id -consoleLog -debug -os win32 -ws
win32 -arch x86

If you're unable to start the app with the above command line, means
that your application might be missing some dependencies, or that swtbot
may have broken some of your apps dependencies causing it to not startup...

Hi Ketan

Thanks for the reply.

As suggested by you, it tried to run the eclipse with the following arguments:

-application com.lm.uc.app.application -consoleLog -debug -os win32 -ws win32 -arch x86

and it was able to launch the application!

and also, the osgi console is able to find my test application:

osgi> apps
org.eclipse.equinox.p2.artifact.repository.mirrorApplication [launchable]
org.eclipse.help.base.helpApplication [launchable]
org.eclipse.equinox.p2.metadata.repository.mirrorApplication [launchable]
org.eclipse.help.base.indexTool [launchable]
org.eclipse.swtbot.eclipse.junit4.headless.swtbottestapplica tion [not launchable]
com.lm.uc.app.application [launchable]
org.eclipse.help.base.infocenterApplication [launchable]
org.eclipse.equinox.app.error [not launchable]
org.eclipse.ant.core.antRunner [launchable]
org.eclipse.swtbot.eclipse.core.swtbottestapplication [not launchable]

but, still it does not lauch my test application.

Hi Ketan

I put some debug lines in the getApplication method in UITestApplication.java to find out the exact reason for not launching the test application. It fails on the condition "runnable instanceof IApplication" and returns null. Following is the modified getApplication method:

private Object getApplication(String[] args) throws CoreException {
// Find the name of the application as specified by the PDE JUnit launcher.
// If no application is specified, the 3.0 default workbench application
// is returned.
String applicationToRun = getApplicationToRun(args);
IExtension extension = Platform.getExtensionRegistry().getExtension(Platform.PI_RUN TIME, Platform.PT_APPLICATIONS,
applicationToRun);

Assert.isNotNull(extension, "Could not find IExtension for application: " + applicationToRun);

// If the extension does not have the correct grammar, return null.
// Otherwise, return the application object.
IConfigurationElement[] elements = extension.getConfigurationElements();
System.out.println("configuration length:" + elements.length);
if (elements.length > 0) {
System.out.println("name of the configuration: " + elements[0].getName());
IConfigurationElement[] runs = elements[0].getChildren("run"); //$NON-NLS-1$
System.out.println("runs length:" + runs.length);
if (runs.length > 0) {
System.out.println("name of the run: " + runs[0].getName());
System.out.println("class name: " + runs[0].getAttribute("class"));
Object runnable = runs[0].createExecutableExtension("class"); //$NON-NLS-1$
System.out.println("Object Class Name:" + runnable.getClass());
if (runnable instanceof IApplication){
System.out.println("returning runnable...");
return runnable;
} else {
System.out.println ("runnable is not an instance of IApplication");
//return runnable;
}
}
}
System.out.println("returning null...");
return null;
}

and it gives the following output:

configuration length:1
name of the configuration: application
runs length:1
name of the run: run
class name: com.lm.uc.app.Application
Object Class Name:class com.lm.uc.app.Application
runnable is not an instance of IApplication
returning null...

Awesome, I think you nailed it :)

The application class uses the legacy IPlatformRunnable interface
(http://goo.gl/inAq) instead of the new IApplication
(http://goo.gl/qXx3) interface.

SWTBot does not support the legacy interface in the interest of keeping
the codebase simple and easy to manage.

See the legacy UITestApplication implementation(http://goo.gl/An90) for
details on how to handle legacy application. I'd suggest creating a
custom 'org.yourcompany.swtbot.eclipse.junit4.headless' fragment with
the legacy UITestApplication instead of swtbot's UITestApplication.
Replace the runTests method in it with the one from swtbot's launcher
for your tests to work correctly.

Alternatively:

Change the UITestApplication so that all instanceof and casting
operations in the start() and getApplication() also handle
IPlatformRunnable in addition to(or instead of) IApplication.

Thanks for the reply. I have changed the UITestApplication to take care of the IPlatformRunnable interface. I am now able to launch the test application successfully.
