Hello,
is it possible to create unit tests for RAP without opening browser? I tried to use RAPTestCase, but what I see is that it creates workbench and opens web browser.
Instead, what I need is to perform some simple user interface logic tests. For example, I have some simple composite, let's say:
public class MyComposite extends Composite {
private Text text;
private Button checkbox;
public MyComposite(Composite parent, int style) {
super(parent, style);
checkbox = new Button(this, SWT.CHECK);
checkbox.addSelectionListener(new SelectionAdapter() {
@Override
public void widgetSelected(SelectionEvent e) {
text.setEnabled(checkbox.isEnabled());
}
});
checkbox.setText("checkbox");
text = new Text(this, SWT.BORDER);
text.setBounds(41, 92, 76, 21);
}
public Button getCheckbox() {
return checkbox;
}
public Text getText() {
return text;
}
}
It's very simple example, that shows that text is enabled when checkbox is checked. In real world I would have more complicated composites, for example - a button that calls some services, and renders data in table, etc. I'd like to test that more complicated cases.
Anyway, I would like to create a test like this:
class MyTest extends RAPTestCase{
Display display ;
Shell shell;
@Override
protected void setUp() throws Exception {
display = Display.getCurrent();
shell = new Shell(display, SWT.NONE);
}
public void testMyComposite(){
MyComposite c = new MyComposite(shell, SWT.NONE);
c.getCheckbox().setSelection(true);
assertTrue(c.getText().isEnabled());
}
}
When I run it as a RAPTestCase it creates Workbench and opens browser. When I run it as a JUnit Plug-in Test case I get problems with getting Display and Shell objects.
When I create Display with new operator:
@Override
protected void setUp() throws Exception {
display = new Display();
shell = new Shell(display, SWT.NONE);
}
then I get:
java.lang.IllegalStateException: No context available outside of the request service lifecycle.
at org.eclipse.rwt.internal.service.ContextProvider.getContext(ContextProvider.java:105)
at org.eclipse.rwt.internal.service.ContextProvider.getRequest(ContextProvider.java:116)
When I create a shell with empty constructor without creating a display:
protected void setUp() throws Exception {
shell = new Shell();
}
then I get:
java.lang.NullPointerException
at org.eclipse.swt.widgets.Widget.isValidThread(Widget.java:918)
at org.eclipse.swt.widgets.Widget.checkWidget(Widget.java:901)
I even tried to use Fixture class from org.eclipse.rap.rwt.testfixture, but I get:
java.lang.IllegalAccessError: tried to access field org.eclipse.rwt.internal.application.ApplicationContext.skipResoureRegistration from class org.eclipse.rwt.internal.application.ApplicationContextHelper

Hi,
yes... it's possible the create plain JUnit tests without problem. You
have to call some Fixture methods in setUp and tearDown to initialize
the environment like:
public class MyTest extends TestCase {
private Display display;
private Shell shell;
@Override
protected void setUp() throws Exception {
Fixture.setUp();
Fixture.fakePhase( PhaseId.PROCESS_ACTION );
display = new Display();
shell = new Shell( display );
}
@Override
protected void tearDown() throws Exception {
Fixture.tearDown();
}
public void testMyComposite() {
....
}
HTH,
Ivan
