StartupRecorder.openRecorder fails with NPE [message #1766104] Thu, 15 June 2017 13:49 Go to next message
Eclipse UserFriend
I am trying to record my application so I can test it.
I am using
Version: Neon.3 Release (4.6.3) Build id: 20170314-1500
jdk1.8.0_101

I added 
org.eclipse.swtbot.generator.ui.StartupRecorder.openRecorder("small Sample");


and it fails with

Exception in thread "main" java.lang.NullPointerException
at org.eclipse.swtbot.generator.ui.GeneratorExtensionPointManager.loadGenerators(GeneratorExtensionPointManager.java:32)
at org.eclipse.swtbot.generator.ui.StartupRecorder$StartRecorderRunnable.run(StartupRecorder.java:57)
at org.eclipse.swt.widgets.Synchronizer.syncExec(Synchronizer.java:233)
at org.eclipse.swt.widgets.Display.syncExec(Display.java:4821)
at org.eclipse.swtbot.generator.ui.StartupRecorder.openRecorder(StartupRecorder.java:122)
at com.small.Sample.main(Sample.java:66)

I have a very small example (error messages are from example) that replicates this. I am sure I am doing something simple incorrectly.

my .classpath is

Hi Keith,

I can reproduce your problem.

The error occurs because the platform's RegistryProviderFactory has not been initialized.

Even though you are including some of the necessary platform plug-ins, the platform itself is not being initialized. Is your application an Eclipse application?

If it is not, then I believe you cannot use the SWTBot Generator to test your application as the generator requires the Eclipse platform.

If you are running from Eclipse, make sure that your Run Configuration's Main tab uses Program to Run: org.eclipse.platform.ide (product) or org.eclipse.ui.ide.workbench (application) or if your application is an RCP, its application id.

If you are running with Maven, make sure your pom.xml has the necessary elements, this might help: https://wiki.eclipse.org/SWTBot/Automate_test_execution#On_a_plugin_project_project_with_Maven_and_Tycho

I am confused. I can't get either of those to work as a Java (or Eclipse) Application (so maybe that's wrong).
I thought the whole point of 
org.eclipse.swtbot.generator.ui.StartupRecorder.openRecorder("small Sample");

was to have a button or menu item that you could press in a normal Java application that would start the recorder.

I have a Java Application that I am trying to record.
I am trying (and failing) to follow the instructions on https://wiki.eclipse.org/SWTBot/Generator

Hi Keith,

The parameter to pass in StartupRecorder.openRecorder(String) is the dialog ID of the SWTBot Recorder dialog to open, e.g. one of:

"org.eclipse.swtbot.generator.dialog.basic" (default)
"org.eclipse.swtbot.generator.dialog.jdt"

Or pass null or empty string to open the default (that can also be set in "org.eclipse.swtbot.generator.dialog" system property).

I'll update the wiki.
