Delicious JellyTools for NetBeans functional testing

Yesterday I had the pleasure of writing some functional tests (for an in house IDE) using JellyTools, NetBeans’ extension to the Jemmy testing framework. The testing APIs offered by Jelly and Jemmy are very intuitive and you can get your GUI test up and running in minutes.

Jemmy provides various types of Swing/AWT  ‘operators‘ that can be used to manipulate GUI components. Examples for Jemmy operators include JTreeOperator, JPopupMenuOperator, JCheckBoxOperator etc.

Jelly extends these and provide NetBeans platform specific convenience operators such as TopComponentOperator, OutputTabOperator, ProjectsTabOperator etc.

In my case, my functional test needed to test my (custom) IDEs build project functionality.

public void testIDEBuild() {
   //utility method to open a project, code not shown here
   //open the IDEs output window
   new OutputWindowViewAction().perform(); 
   //get a handle to the Projects tab in NetBeans
   ProjectsTabOperator projects = new ProjectsTabOperator();
   //get a handle to the project tab's explorer tree
   JTreeOperator tree = new JTreeOperator(projects);
   //find the node that contains the RMB action 'Build'
   TreePath path = tree.findPath(PROJ_NAME+"| My Applications"); 
   //get a popmenu operator
   JPopupMenuOperator menu = new JPopupMenuOperator(tree.callPopupOnPath(path));   
   //call the 'Build' action
   //get the output tab containing 'proj-build' ANT output
   OutputTabOperator outputTabOp = new OutputTabOperator("proj-build"); 
   //give 2 mins for building
   outputTabOp.getTimeouts().setTimeout("ComponentOperator.WaitStateTimeout", 120000);
   //check for "BUILD SUCCESSFUL" if not the test fails
    outputTabOp.waitText("BUILD SUCCESSFUL");
