I am working on Selenium with Java and using Listeners.
I created the class, imported the TestNG, and then added method as;
Public class Listener implements ITestListener{
}
I got an error at "ITestListner" and then imported "ITestListner(org.testng). After this it was expected that I will get an error for "Listener" but I didn't get any error.
I tried creating with abstract class but still didn't get the error.
package com.testng;
import org.testng.ITestListener;
public class Listeners implements ITestListener{
}
The expectation is when I move the cursor over "Listeners" I should get "Add unimplemented methods" option.
Right click(on the Listeners class ) -> go to source-> click on overide/implement methods -> select the check boxes for the ITest listener (make sure all check box inside it should be checked )->click on oK. That's it !!!
As i got to know from the below link - TestNG 7.0.0 uses JDK8 and with it default methods within interfaces. What this means is that every listener would now have a default implementation (which doesn't do anything ) for all methods defined within the interface.
So now you won't see those indications from the IDE. The biggest benefit of default methods in interfaces is that let's say you are implementing an interface that has 10 methods defined in it, you can just implement whatever you need and the rest of the behavior comes via the default methods in the interface.
Reference-
https://github.com/cbeust/testng/issues/1964
Right click on the class --> select source --> choose override/implement methods --> then pick the methods you'd like to implement.
Try downgrading the TestNg version to 6.14.3.
It worked for me.
The Best solution is go to the source tab besides the File-Edit options and click the Overide/implement methods and you are set
All methods in ITestListener interface changed to default from 7 version onwards. You can call them with class object where you implemented interface.

One of the features I like of Eclipse is that when creating Java classes, a wizard is available to specify different properties for the class. Like its package, class to extend from...etc (see below in the screen cap).
Does IntelliJ provide something similar? I created a class but the process wasn't smooth. I had to...mark /java directory as Source Root...create new package...create a new class...and now, I want to extend from a different class other than Object... I would like to avoid doing this step by step, if possible.
I am using IntelliJ Community Edition, version 15.
No, there is no such wizard. Marking the directory as a source root is a one-time action, and is normally taken care of when you create the project. To specify the package, you can enter the package and class name directly in the "New Java class" dialog. If you want to extend a different class, the code completion will help you enter the "extends" or "implements" keyword and specify the base class name.
You can make package at the same time as you create java class.
When you do right click -> new -> java class : at the place of the name you can mark
my.new.package.ClassName and IntelliJ will create the package : my.new.package for you.
For more explication you can visit this page.
In IJ you don't need to write all of this stuff manually. Just right click on the method an choose Go to Test or press Ctrl-Shift-T. This functionality is described on the help page IntelliJ IDEA 15.0 Help /Creating Tests.
In the Create Test dialog:
Select the testing library to be used.
If the selected library is missing in your module, click the Fix button. As a result, the corresponding library will be automatically added to the module libraries.
Define the name and location of the test class to be generated.
In the Class name field, specify the name of the stub test class to be generated.
In the Superclass field, IntelliJ IDEA suggests the appropriate super class for JUnit3. For JUnit 4 and TestNG, this field is blank.
In the Destination package field, define where the generated test class should be placed.
Specify whether you want the setUp()/tearDown() methods (for JUnit), or the #Before/#After annotations to be generated.
In the table that shows the list of all the methods of the source class, select the ones you want to generate test methods for.
Click OK.
In addition to other answers if you hit Alt-Enter on any interface or abstract class name one of the intention options will be to create an implementation.
When I tell to Eclipse to generate methods (Add unimplemented methods popup) from inherited interface/abstract class, can I configure it to make these methods final by default ?
I'm aware of the Save actions hook in Eclipse but there's no preconfigured action to specify something like: "Add final modifier to method signature" or am I missing something ?
Also, when I create a class, is there a way to check the checkbox final by default ? I know it's not hard to do it by hand but it could be useful for me in case I forgot to check it. I'm aware of this similar question but in 2011 there was no answer (maybe now there's one !).
PS: you can assume I'm using the latest version of Eclipse (Mars - 4.5.0).
Since I assume you don't like the answer given in the link you specified, which is to create your own custom 'new class wizard' for Eclipse, the answer is: No
I am looking for some kind of refactoring feature in Eclipse to generate methods in implementation classes from an interface class. Let's say I have JavaClassImpl1 and JavaClassImpl2, which implement JavaClassInterface. What I'd like to do is when I add a method to JavaClassInterface, the refactoring option is to generate empty methods in all implementation classes, in this case, in JavaClassImpl1 and JavaClassImpl2.
If you haven't implemented all of the required methods in eclipse, it will show a bunch of compile-time errors in your class (the class will have a red underline).
If you hover over the class name, a pop-up will appear with available quick fixes, one of which will be Add unimplemented methods. If you select that eclipse will generate a stub for each unimplemented method.
Another way to access the same function is to rightclick in your class and select Source -> Override/Implement Methods... which will pop up a wizard which allows you to select which methods you would like eclipse to stub out for you.
Update
If the change you make to your interface is done via one of the eclipse refactor tools, then eclipse will generally update references to the thing that was changed. For instance, if you do a Refactor -> Introduce Parameter Object... on a method in your interface, then eclipse will automatically update implementing methods.
If you're adding code manually, eclipse doesn't even know about the change until the next time you compile, and you'll have to explicitly ask eclipse to refactor the code.
Eclipse:
When displaying a list of methods (ctrl-space), is there a way to have methods found in that class have names in bold? Netbeans has or at least had a feature that would bold the names of methods found within that class while inherited methods remained normal text.
This made it very easy to know what methods are from within the class you are editing.
Is there a way to do this in the latest version of Eclipse?
Thanks.
It seems eclipse does not support it.
What I do in such cases (workaround):
Open the affected class (Navigate -> Open Type...)
Press CTRL-O, this will show the methods implemented in this class.
Press CTRL-O again, this will also show the inherited methods.
As you know, eclipse provides with a nice way to implement unimplemented methods if a child class does not have them implemented. Is there any way to apply this to all child classes?
My problem is that I have to do this for each child class when there are 50 of them. I would appreciate any help.
select the top level package in your package explorer. Go to the 'Problems' view. There should be the list of errors of "The type Foo must implement the inherited abstract method Parent.foo()" (for given class/method names). Right click on the error, select "Quick Fix". You can select the "Add unimplemented methods" option and click the "Select All Button" to select all the child classes.
EDIT: This works even for multiple methods per parent class.
Problem can be solved using "source/cleanup" feature, after applying few changes in eclipse as:
Make your own project specific profile for Java Code Style/Clean Up:
Select the Project/BuildPath/Configure Build Path> Click on Java Code Style/Clean Up > Check Enable Project Specific Settings/Edit> Check Add unimplemented methods and give Profile name.
2. Select Project/Source/Clean Up, it will show project name and the profile name we created. Click on finish.
Now method will be added to all child classes:
Once profile is created, this works even for multiple methods added in the interface or abstract class. Just follow step 2.
For Android Studio guys below is the workaround for it,
Add this method in your interface or abstract class,
#Override
public void methodInInterfaceOrAbstract()
{
// this must me in interface or abstract class which will be implemented by child classes
}
Then right click the java file, select the option "Refactor" then select the option "Push members down". Select the method which you want to push down to all child classes and click refactor.
Your new method added in interface or abstract class will be moved to all child classes.
Now you need to add the declaration of the method in interface or abstract class again as the method was moved to all child classes.
