Hi!
I am tring to apply SWTBot as our GUI automation test tool, it's very easy to get started, but i encounter a problem. I just import a project, and want to select right-click menu and do something. i used following code to select right-click menu:

SWTBotView view = bot.viewByTitle("Package Explorer");
List controls = new ChildrenControlFinder(view.getWidget()).findControls(WidgetOfType.widgetOfType(Tree.class));
if (controls.isEmpty())
fail("Tree in Package Explorer View was not found.");
SWTBotTree tree = new SWTBotTree((Tree) controls.get(0));

SWTBotTreeItem item = tree.getTreeItem("AndroidPdfViewer");
if(item == null){
throw new WidgetNotFoundException("Could not find menu: test");
}
item.setFocus();

but Package Explorer cannot be found with error

org.eclipse.swtbot.swt.finder.exceptions.WidgetNotFoundException: Could not find widget.

But if i add create a new project test, try the test above then it's okay, i have no idea about what's going on. Do i use it in a wrong way? or i need update something?

Hi Joanna,

Are you sure that the Package Explorer view is indeed displayed when calling 'SWTBotView view = bot.viewByTitle("Package Explorer");'?
If not you'll have to either switch to the appropriate (Java?) perspective or explicitly show the Package Explorer view through SWTBot API.
When you creating a new project, eclipse may automatically switch to the Java perspective (depending on your preferences perhaps), which would explain the symptoms you describe.

Hi,Benjamin~
Thanks for your reply, i tried again and found like you mentioned, if import project only, package explorer didn't activate, but project explorer activated, so after changing SWTBotView view = bot.viewByTitle("Package Explorer") to SWTBotView view = bot.viewByTitle("Project Explorer"), it works well. I found during my test, lots of errors are caused due to wrong title usage. I didn't have eclipse and SWTBot experience before, is there any better way to avoid the title related errors, or any documents reference?

Hi Joanna,

I usually try to access the labels directly from the eclipse plug-ins that define them (either in a messages.properties file or plugin.properties file). Note that some labels are also available through final static String constants (example: org.eclipse.ui.internal.ide.IDEWorkbenchMessages.OpenWorkspaceAction_other in org.eclipse.ui.ide plugin).

For instance:
* "Package Explorer" is defined by the property key "packagesViewName" in the org.eclipse.jdt.ui plugin.properties file.
* "Project Explorer" is defined by the property key "Common_Resource_Navigator" in the org.eclipse.ui.navigator.resources plugin.properties file.

However some of those keys are very hard to find: you may spend quite a lot of time browsing the eclipse plug-ins before finally finding the one(s) you are looking for.

Proper handling of those properties also helps globalizing your SWTBot test cases (i.e run them on different locales).

Cheers,
