SWTBot testing controls which extend org.eclipse.ui.forms.MasterDetailsBlock [message #910769]

I'm trying to automate the swtbot ui testing for an eclipse plugin, with maven.

The particular eclipse plugin has a custom control which is extended from org.eclipse.ui.forms.MasterDetailsBlock.

This custom control contains a org.eclipse.swt.widgets.Tree.

I'm using org.eclipse.swtbot.eclipse.finder;bundle-version="2.0.5" and org.eclipse.swtbot.swt.finder;bundle-version="2.0.5".

SWTBot couldn't find any tree when I attempt to search as follows,

SWTBotTree tree = bot.tree(); for (SWTBotTreeItem treeItem : tree.getAllItems()) {}

I tried with (which is working for org.eclipse.ui.forms.widgets.FormText),
MasterDetailsBlock masterDetailsBlock=bot.widget(widgetOfType(MasterDetailsBlock.class));

But following syntax error was shown by the eclipse (3.7.2).

'Multiple markers at this line - Bound mismatch: The generic method widgetOfType(Class) of type WidgetMatcherFactory is not applicable for the arguments (Class). The inferred type MasterDetailsBlock is not a valid substitute for the bounded parameter - Bound mismatch: The generic method widget(Matcher) of type SWTBotFactory is not applicable for the arguments (Matcher). The inferred type MasterDetailsBlock is not a valid substitute for the bounded parameter '

Please suggest me any workaround or solution to this issue.

Does SWTBot support to test org.eclipse.ui.forms.MasterDetailsBlock components? In the negative case how to contribute that facility?

Thanks in advance.

The method "widgetOfType" signature is:
<T extends org.eclipse.swt.widgets.Widget> org.hamcrest.Matcher<T>
inUIThread(org.hamcrest.Matcher<?> matcher)
As you can see, it expects the argument T to extend
"org.eclipse.swt.widgets.Widget". A MasterDetailsBlock is not a Widget,
it's more a kind of Factory or Controller. You can't access it with
SWTBot APIs.

> In the negative case how to contribute that facility?

It does not make sense to support this in SWTBot since a
MasterDetailsBlock is not a UI component, it's a logical one.
Instead, you can seek into the details part using regular SWTBot APIs,
just as if there were no MasterDetails in your editor.

Thanks for the reply Mickael..!!

Of course, I'm a beginner and am trying test/access a component via SWTBot. The responsible class, which extends MastersDetailsBlock uses org.eclipse.ui.forms.widgets.FormToolkit to create a section-> composite-> tree.

(only relevant lines of code are given below)

Section section = toolkit.createSection(parent, Section.DESCRIPTION | Section.TITLE_BAR);

Composite client = toolkit.createComposite(section, SWT.WRAP);

tree = toolkit.createTree(client, SWT.NULL);

EclipseSpy View could locate the tree as follows.
Location:
//Shell/-1//Composite/4//Composite/0//Composite/6//Composite/0//Composite/0//CTabFolder/0//ScrolledForm/1//Form/0//LayoutComposite/1//MasterDetailsBlock$MDSashForm/0//Section/0//LayoutComposite/2//Tree/0

I could access to the section and composite but not the tree.
I have tried as follows.

SWTBotTree tree = bot.tree();
for (SWTBotTreeItem treeItem : tree.getAllItems()) {}

and alternatively

final Tree tree1 = bot.widget(widgetOfType(Tree.class));
asyncExec(new VoidResult() {
public void run() {
for (TreeItem treeItem : tree1.getItems()) {
if(treeItem.getText().contains("myDataService.dbs")) {
tree1.select(treeItem);

}
}
}

Neither of them couldn't find any trees.

I also tried the composite.getChildern()and tried to get the class name of each of them. Tree class wasn't there.

Is it a concern with the creation of the tree (as mentioned at the beginning)??
How to trace the tree component?
Why couldn't swtbot find the tree while the eclipse_spy could?
Is there any other available control tracking tools?

Thanks in adavance.

hi,
Sorry for previous post which off the head.
I could simply access the tree as follows and able to select the TreeItem. But couldn't work with
its context menu.

bot.cTabItem("xxxx").activate();
SWTBotEditor swtBotEditor = bot.activeEditor();
SWTBotTreeItem node = swtBotEditor.bot().tree()
.getTreeItem("yyyy)");
node.setFocus();

node.select().contextMenu("zzzzz").click(); //error

An error occurs and relevant section is as follows.

java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
at java.util.ArrayList.RangeCheck(ArrayList.java:547)
at java.util.ArrayList.get(ArrayList.java:322)
at org.eclipse.swtbot.swt.finder.widgets.AbstractSWTBot.contextMenu(AbstractSWTBot.java:460)
at org.eclipse.swtbot.swt.finder.widgets.SWTBotTreeItem.contextMenu(SWTBotTreeItem.java:553)
......

Anyway, I could do the same simulation inside Package Explorer and close projects.

I found the responsible code segment is "menuFinder.findMenus(matcher).get(0)".

Does it mean it couldn't find any menuItems?
Please help?

I don't think so.

Is the view or part or the shell that contains the Tree active when
looking for bot? If not, you should retrieve it with SWTBot API, and use
setFocus() or activate() on it to ensure bot will look in the right
piece of UI.

Glad it works better now

Are you using Eclipse 4? It appears that SWTBot has some issues with
menus in Eclipse 4. See:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=388306
https://bugs.eclipse.org/bugs/show_bug.cgi?id=384621

Maybe your issue is related to one of this issue. If you have time to
investigate and try contributed patches, you're very welcome.
Please add you use-case/thoughts/feedback/patches to the relevant
issues, and create new issues if necessary.

hi,
thanks for the reply.
I referred this forum [1] and used 'ContextMenuHelper'to solve my context-menu issue.

Can you please suggest me some good (deep) references regarding swtbot threads?

Thanks in advance.
