The following is my piece of code that tries to invoke the extract method refactoring. Please let me know if you find anything wrong with the way I'm having SWTBot invoke this refactoring. The whole test class is available at our repository.

@Test
public void shouldExtractMethod() throws Exception {
	SWTBotEclipseEditor editor= bot.editorByTitle(TEST_NAME + ".java").toTextEditor();
	editor.setFocus();
	// editor.selectLine(5);
	editor.selectRange(5, 2, 37 - 9);
	System.out.println(editor.getSelection());
	System.out.println(editor.cursorPosition());
	SWTBotMenu extractMethodMenuItem= bot.menu("Refactor").menu("Extract Method...");
	//FIXME: The following assertion fails.
	assertTrue(extractMethodMenuItem.isEnabled());
	extractMethodMenuItem.click();
	// editor.pressShortcut(Keystrokes.SHIFT, Keystrokes.ALT,
	// KeyStroke.getInstance("M"));
	bot.shell("Extract Method").activate();
	bot.textWithLabel("Method name:").setText("m");
	bot.button("OK").click();
	bot.sleep(200000);
}

Hi,

I also posted something similar (some options on property pages are disabled) here: http://www.eclipse.org/forums/index.php?t=msg&th=175593

Hi,

are you sure that your menu shouldn't be disabled?
You can check the activeWhen option on the menu/handler.
On the screenshot is the menu really disabled?

Yes, I'm sure the menu item shouldn't be disabled, because when I follow the script manually, the menu item is enabled.

I've uploaded the screenshot taken by SWTBot at http://i51.tinypic.com/annb75.jpg

SWTBot doesn't open the menus. So, we cannot tell from the screenshot if the "extract method" refactoring is enabled. But, the failure of the following assertion shows that this menu item is actually disabled.

assertTrue(extractMethodMenuItem.isEnabled());

Just wanted to mention that our SWTBot test has moved to a new location. So, if you need to take a look at the whole source code to debug it, please refer to the new location.

We haven't heard back from anyone about ways to troubleshoot our problem. So, we decided to update you about our progress.

We've been able to fire other refactorings like Extract Constant and Inline constant using SWTBot.

We believe that the problem with invoking the Extract Method refactoring through SWTBot is that it's the only (AFAIK) refactoring that has an enabled/disabled state from the Refactor menu. It tries to check if something is actually selected in the text editor before it enables itself from the menu. Somehow the way SWTBot selects the text in the editor does not communicate it back properly to the Extract Method action item. We believe that this is the problem.

Hello Mohsen,

SWTBotEclipseEditor.selectRange() and selectLine() methods are asynchronous
so you should have a wait condition immediately after the select which checks
for the cursor position before doing anything else (like clicking a context
menu) - the cursor should be positioned at the beginning of the selection.
An example code from one of our tests:

programEditor.selectLine(3);
waitForCursorPosition(programEditor, 3, 0);
programEditor.pressShortcut(Keystrokes.DELETE);

Thanks!

Hi Petar

Thanks for the response. We have tried it (and maybe I'm doing
something wrong below) but that still does not allow the Extract Method
refactoring to be invoked. As Mohsen mentioned, this is the only
refactoring that we have encountered so far that cannot be selected
using the way we have below.

Here is the relevant code snippet:

@Override
protected void prepareRefactoring() {
final SWTBotEclipseEditor editor= bot.editorByTitle(TEST_FILE_NAME +
".java").toTextEditor();

// Extract Method Refactoring
editor.setFocus();

final int cursorLinePosition= 5;
final int cursorColumnBeginPosition= 8;
int cursorColumnEndPosition= 36;
editor.selectRange(cursorLinePosition, cursorColumnBeginPosition,
cursorColumnEndPosition - cursorColumnBeginPosition);

DefaultCondition condition= new DefaultCondition() {

@Override
public boolean test() throws Exception {
return editor.cursorPosition().line == cursorLinePosition;
}

@Override
public String getFailureMessage() {
return "Cannot update cursor position in editor";
}

};

bot.waitUntil(condition, 5000, 100);
System.out.println("Cursor position:" + editor.cursorPosition());

SWTBotMenu refactorMenu= bot.menu("Refactor");
assertTrue(refactorMenu.isEnabled());

SWTBotMenu extractMethodMenuItem= refactorMenu.menu("Extract Method...");
assertTrue(extractMethodMenuItem.isEnabled());

extractMethodMenuItem.click();
}

The System.out.println("Cursor position:" + editor.cursorPosition());
shows that the cursor is at the right position but the
assertTrue(extractMethodMenuItem.isEnabled()) statement still fails.

Am I using the waitUntil(...) method wrongly?

Thank you.
