I want to learn how to test Java Swing user-interfaces and would like to try Jemmy v2. When trying to follow the instructions on http://jemmy.java.net/tutorial.html I ran into trouble. I created a new project currently consisting of only the following class, which I want to start the application I want to test and create a reference to this application. Unfortunately it seems I'm doing something fundamentally wrong, as an "java.lang.ClassCastException" exception is thrown as soon as the application i want to test is activated.
import org.netbeans.jemmy.*;
import org.netbeans.jemmy.explorer.*;
import org.netbeans.jemmy.operators.*;
public class Main implements Scenario
{
public int runIt(Object param)
{
try {
//start application
new ClassReference("org.netbeans.jemmy.explorer.GUIBrowser").startApplication();
//wait frame
new JFrameOperator("Tic-Tac-Toe 3.0");
} catch(Exception e) {
e.printStackTrace();
return(1);
}
return(0);
}
public static void main(String[] argv)
{
String[] params = {"sut2.TicTacToe"};
org.netbeans.jemmy.Test.main(params);
}
}
The exception I get:
Shortcut test events
Using org.netbeans.jemmy.drivers.DefaultDriverInstaller driver installer
Executed test sut2.TicTacToe
Exception in thread "main" java.lang.ClassCastException: sut2.TicTacToe cannot be cast to org.netbeans.jemmy.Scenario
at org.netbeans.jemmy.Test.testForName(Test.java:265)
at org.netbeans.jemmy.Test.<init>(Test.java:113)
at org.netbeans.jemmy.Test.run(Test.java:176)
at org.netbeans.jemmy.Test.run(Test.java:202)
at org.netbeans.jemmy.Test.main(Test.java:250)
at Main.main(Main.java:25)
sut2.TicTacToe is a class that implements ActionListener, but does not extend JFrame (I tried another even simpler java program that did, but got the same result). Inside this class a JFrame object is created and panels with GUI components are added.
Could you please tell/show me what I'm doing wrong and how I should properly setup Jemmy v2?
It looks that you pass the wrong params
to org.netbeans.jemmy.Test.main
. It expects implementation of Scenario
. Assuming that Main
is in default package, try the following:
public static void main(String[] argv) {
String[] params = { "Main" };
org.netbeans.jemmy.Test.main(params);
}
You can specify the package of Main
as needed.
