Widget not found exception [message #481753] Mon, 24 August 2009 08:39 Go to next message
Eclipse UserFriend
Hi !
I use SWTBot to test my Eclipse Plug-in.

Currently i am trying to create some preconditions
for each test case(there should be a project with
a test file in the workspace. after the project and
file creation, i intent to open the file in the text
editor and print some text in it).

My test:

@RunWith(SWTBotJunit4ClassRunner.class)
public class MyFirstTest {

private static SWTWorkbenchBot bot;

@BeforeClass
public static void beforeClass() throws Exception {
bot = new SWTWorkbenchBot();
bot.viewByTitle("Welcome").close();
SWTBotPerspective perspective =
bot.perspectiveByLabel("ConfigModeler");
perspective.activate();

// Create a project
bot.menu("File").menu("New").menu("Project...").click();
bot.shell("New Project").activate();
bot.tree().expandNode("General").select("Project");
bot.button("Next >").click();
bot.textWithLabel("Project name:").setText("test
project");
bot.button("Finish").click();

// Create a file
bot.menu("File").menu("New").menu("Other...").click();
bot.shell("New").activate();
bot.tree().
expandNode("Config Modeler").
select("Source file");
bot.button("Next >").click();
bot.textWithLabel("Container:").setText("test project");
bot.button("Finish").click();

SWTBotEditor botEditor =
bot.editorByTitle("new_product.cml");
SWTBotEclipseEditor textEditor =
botEditor.toTextEditor();
for(int i=0; i<10; i++) {
textEditor.typeText("test");
}
}

@Test
public void test...() throws Exception {
....
}
}

When i start the test, i get the following exception:

org.eclipse.swtbot.swt.finder.exceptions.WidgetNotFoundExcep tion: Could

the problem was removed with the activation of the eclipse main window

SWTBotShell shell = bot.activeShell();

// Create a project
bot.menu("File").menu("New").menu("Project...").click();
bot.shell("New Project").activate();
bot.tree().expandNode("General").select("Project");
bot.button("Next >").click();
bot.textWithLabel("Project name:").setText("test
project");
bot.button("Finish").click();
shell.activate();

Yes, I've run into that one.

Here's another gotcha ...

bot.menu("Project").menu("Build Automatically").click();

had to be changed to

bot.menu("Project",1).menu("Build Automatically").click();

in my test case, even though the "Project" menu is in the main menu bar.

Seems like there should be some obvious heirarchy to the menu search. I
didn't figure out which "Project" it was finding, but apparently it found
something else first.
