Hi!

I'm trying to get started with SWTBot and followed this guide: http://swtbot.com/user-guide/, but I was using Eclipse IDE as the application to test.

I chose to select "Help" -> "About Eclipse" menu item:

@RunWith(SWTBotJunit4ClassRunner.class)
public class SampleTest {
	private SWTWorkbenchBot bot;
	  @Test
	  public void selectSomeMenus() throws Exception {
		  SWTBotMenu m1 = bot.menu("Help");
		  SWTBotMenu m2 = m1.menu("About Eclipse");
		  m2.click();
		  Thread.sleep(5000);
	  }
	  @Before
	  public void setup() {
	    bot = new SWTWorkbenchBot();
	  }
}


but got back WidgetNotFoundException.

I was about to give up but tried with other menu items (eg. "Help -> Welcome") and to my surprise most of them worked.

Unfortunately, one that I'm interested of ("Project -> Clean...") does not work.

Why are "Help -> About Eclipse" or "Project -> Clean..." special? How can I select them?

I have 32bit Eclipse Helios on 64bit Win7. SWTBot is 2.0.2

Hi

Are you sureyour application window is on the top-level of your Window System and hasthe focus? It is mandatory for SWTBot tests to run,

I tried again and checked that window is in focus. I still get always same result -- some menu items are always "clickable" and some give always error. Seems that error never comes from accessing the topmost menu.

SWTBotMenu m1 = bot.menu("Help");
SWTBotMenu m2 = m1.menu("About Eclipse"); /// this line gives error

Aivar,

Did you check the syntax of the menu item's label you are trying to activate. In my Helios IDE for instance, in the "Help" workbench menu, there isn't any "About Eclipse" menu item but there is one "About Eclipse SDK". Sorry if this seems like a lame answer, but I have faced this kind of label syntax errors quite a few times.

Regarding the 'Project -> Clean' scenario submitted by Joanna, I was quite surprised to face the very same issue. I investigated a little bit and finally decided to refactor Stefan Seelmanns' ContextMenuHelper contribution (usually pops-up in lots of context menu related issues in this forum) into a WorkbenchMenuHelper class (note that I had very little to-do to adapt his code to the workbench menu-bar items scenario).

It seems to work fine for me.

  /**
   * Clicks the context menu matching the text.
   * 
   * @param text
   *          the text on the context menu.
   * @throws WidgetNotFoundException
   *           if the widget is not found.
   */
  public static void clickContextMenu(
      final SWTBotShell shell, final String... texts) {
    // fetch
    final MenuItem menuItem = getContextMenu(shell, texts);

    // click
    click(menuItem);

    // hide
    UIThreadRunnable.syncExec(new VoidResult() {
      public void run() {
        hide(menuItem.getParent());
      }
    });
  }

  private static MenuItem getContextMenu(
      final SWTBotShell shell, final String... texts) {
    final MenuItem menuItem = getContextMenuImpl(shell, texts);
    if (menuItem == null) {
      throw new WidgetNotFoundException("Could not find menu: " + computeMenuTrace(texts));
    }
    return menuItem;
  }

  private static MenuItem getContextMenuImpl(
      final SWTBotShell shell, final String... texts) {
    traceMenu(texts);

    // show
    final MenuItem menuItem = UIThreadRunnable
        .syncExec(new WidgetResult<MenuItem>() {
          public MenuItem run() {
            MenuItem menuItem = null;
            Menu menu = shell.widget.getMenuBar();
            for (String text : texts) {
              @SuppressWarnings("unchecked")
              Matcher<?> matcher = allOf(instanceOf(MenuItem.class),
                  withMnemonic(text));
              menuItem = show(menu, matcher);
              if (menuItem != null) {
                menu = menuItem.getMenu();
              } else {
                hide(menu);
                break;
              }
            }

            return menuItem;
          }
        });
    return menuItem;
  }

Try this
bot.menu("Help").menu("&About Eclipse").click();

It worked for my eclipse helios and it is because mnemonic "A" in that menu item. Hope this will help.

Hi, Mladen:
Thanks,i tried bot.menu("Help").menu("&About Eclipse").click(); for Help->About Eclipse, it works fine.
Hi, Benjamin:
I tried your suggestion for Project->Clean... scenario, but it seems not work well for me, i am not sure whether there is something wrong when i use it like:
SWTBotShell shell = bot.shell("Clean");
String[] paths={"Project","Clean..."};
clickContextMenu(shell,paths);
Benjamin, could you show me how you use it?

Joanna,

The below code seems to work fine for me:
    SWTBot bot = ...;
    SWTBotShell shell = bot .shells()[0].activate();
    SWTBotMenu menu = new SWTBotMenu(WorkbenchMenuHelper.getContextMenu(shell,
        "Project", "Clean..."));
    menu.click();
    swtBot.shell("Clean").activate();
    swtBot.button().click();
  }


Cheers,

Hi, Benjamin
Thank you so much for your kindly help, it works well with your way, and for my previous code, it can work after referring to your method like this:
SWTBotShell shell = bot .shells()[0].activate();
ContextMenuHelper.clickContextMenu(shell,"Project", "Clean...");
bot.shell("Clean").activate();
bot.button().click();

SWTBotShell shell = bot .shells()[0].activate(); this means activate current shell?

Hi Joanna,
SWTBotShell shell = bot .shells()[0].activate();

This code actually make sure that the eclipse workbench shell is activated. It may not be the current shell: for instance if you have multiple dialog/wizard panels open you can have something like that:

  • bot .shells()[0]: the eclipse workbench shell
  • bot .shells()[1]: your wizard shell
  • bot .shells()[2]: your error message dialog

Note that some of the shells returned by
bot .shells();
may not actually be visible, thus the returned array may have more elements than you expect.
