Hi,

I have a tree view, I have some actions which are added to the
ToolbarManager as follows,

IToolBarManager mgr = getViewSite().getActionBars().getToolBarManager();
mgr.add(exitAction);
When I am testing this method using JUnit, getViewSite() is coming as a
null and getting NullPointerException,

How can I get the getViewSite() not null;

Pls help me...

Thanks,
Swetha

1) make sure you are running a JUnit plug-in test instead of a normal
JUnit test

2) make sure you open a workbench window and either find the view or
show it if it is not already visible.

executing all the test cases..

Please post the snippet that is your JUnit test method. The important
code ... how are you find the workbench window? How are you finding
your open view?

Hi,

This is the test method..

public class CustomerViewTest extends TestCase
{
CustomerView custView;

@Before
public void setUp() throws Exception
{
custView = new CustomerView();

PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().
showView("com.sequenom.everest.ui.CustomerView");
}

@After
public void tearDown() throws Exception
{

}
// Testing
@Test
public void testCreateTreeWidget()
{
custView.createWidget(PlatformUI.getWorkbench()
.getActiveWorkbenchWindow().getShell());
Assert.assertNotNull(custView.tree);
MouseEvent g;
custView.tree.getTree();
}

}

When I am testing the createWidget() method in CustomerView class , the
NullPointerExcepton is coming at the line,

getSite().setSelectionProvider(tree);

getSite() is coming as null;

Thanks,
Swetha

This is the part that won't work.

In your test, use IWorkbenchPage#findView("your.view.id") to get custView

Show us the snippet of code ... i.e. your setup and test ... the code
you wrote works fine when I run it :-)

Hi,

The following is the method I am testing,

public void createWidget(Composite parent)
{
tree = new TreeViewer(parent, SWT.BORDER);
GlobalVariablesClass.modifier = new TreeCellModifier(tree);
tree.setCellModifier(GlobalVariablesClass.modifier);

tree.setColumnProperties(new String[] { "ProjectWidget" });

tree.setCellEditors(new CellEditor[] { new TextCellEditor(tree
.getTree()) });

getSite().setSelectionProvider(tree);

// Adding Actions to context menu,Menubar and Toolbar

}

And the corresponding test method in JUnit is,

public class CustomerViewTest extends TestCase
{
CustomerView custView;

@Before
public void setUp() throws Exception
{
super.setUp();
custView = new CustomerView();

PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().findView( "com.sequenom.everest.ui.CustomerView");

}

@After
public void tearDown() throws Exception
{
super.tearDown();

}

@Test
public void testGetTreeWidget()
{
custView.createWidget(PlatformUI.getWorkbench()
.getActiveWorkbenchWindow().getShell());

Assert.assertNotNull(custView.tree);
}

}

}

The line getSite().setSelectionProvider(tree) , getSite() is coming as
null and causing NullPointerException

Thanks,
Swetha

I told you this wouldn't work.

What I mean is something like:
public void testGetTreeWidget() {
custView =
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().showView( "com.sequenom.everest.ui.CustomerView");
Assert.assertNotNull(custView.tree);
}
