Java GUI Testing - JFCUnit Introduce

Java GUI Testing - JFCUnit Introduce

Background:

JFCUnit is an extension to the popular testing frameworkJUnit. This document assumes you are familiar with the usage of JUnit. If not, visit the main JUnit website where there are a number of links to some excellent resources on the subject.

 

 

        Environment setup & JFCUnit installing…

Download below jars: JUnit.jar 3.7 or greater, JFCUnit.jar, jakarta-regexp-1.5.jar 

Install JRE1.4 or greater & Eclipse IDE

 

        A Sample Java GUI & JFCUnit Test

1.        Deploy downloaded jars into your project class path, see following image

 

 

2.        create java GUI sample codes

package com.fish.ui;

import java.awt.BorderLayout;

import java.awt.FlowLayout;

import javax.swing.JButton;

import javax.swing.JDialog;

import javax.swing.JLabel;

import javax.swing.JPanel;

import javax.swing.JTextField;

 

publicclass NewTestViewImplextends JDialogimplements TestView {

 

   /**

    *

    */

   privatestaticfinallongserialVersionUID = 1L;

 

   private JTextFieldnameField;

   private JButtonsubmitButton;

   private JButtoncancelButton;

   private JLabelnameLabel;

   privatebooleanproceed =false;

 

   public NewTestViewImpl(Object object) {

      // super(object);

      initComponents();

      layoutComponent();

   }

 

   privatevoid initComponents() {

      this.nameField = new JTextField(15);

      this.submitButton = new JButton("OK");

      this.cancelButton = new JButton("Cancel");

      this.nameLabel = new JLabel("Test Name:");

   }

 

   privatevoid layoutComponent() {

      JPanel topPane = new JPanel();

      topPane.add(nameLabel);

      topPane.add(nameField);

      JPanel buttonPane = new JPanel();

      buttonPane.setLayout(new FlowLayout());

      buttonPane.add(submitButton);

      buttonPane.add(cancelButton);

      getContentPane().add(topPane, BorderLayout.NORTH);

      getContentPane().add(buttonPane, BorderLayout.LINE_END);

      pack();

   }

   

 

   public String getTestName() {

      returnnameField.getText();

   }

   

   publicvoid setTestName(String testName) {

      this.nameField.setText(testName);

   }

 

   publicvoid display() {

      this.setVisible(true);

   }

 

   publicboolean proceed() {

      returnproceed;

   }

 

   publicboolean cancelled() {

      return !proceed;

   }

 

   publicstaticvoid main(String[] args) {

      new NewTestViewImpl(null).setVisible(true);

   }

 

   publicvoid setupJFCNames() {

      nameField.setName("testNameField");

      submitButton.setName("SubmitButton");

      cancelButton.setName("CancelButton");    

   }

 

   publicvoid addListener(Listener listener) {

      submitButton.addActionListener(listener);

      cancelButton.addActionListener(listener);

   }

 

 

   publicvoid closeView() {

   

   }

 

 

   publicvoid openView() {

 

   }

}

 

3.        JFCUnit test codes

package com.fish.ui.test;

 

import javax.swing.JButton;

import javax.swing.JComponent;

import javax.swing.JTextField;

 

import com.fish.ui.NewTestViewImpl;

 

import junit.extensions.jfcunit.JFCTestCase;

import junit.extensions.jfcunit.JFCTestHelper;

import junit.extensions.jfcunit.TestHelper;

import junit.extensions.jfcunit.finder.NamedComponentFinder;

import junit.framework.Test;

import junit.framework.TestSuite;

 

publicclass NewTestViewImplTestextends JFCTestCase {

   private NewTestViewImplnewTestViewImpl =null;

   private TestHelperhelper =null;

 

   public NewTestViewImplTest(String name) {

       super(name);

   }

 

   protectedvoid setUp()throws Exception {

      super.setUp();

      helper =new JFCTestHelper();

      newTestViewImpl =new NewTestViewImpl(null);

      newTestViewImpl.setupJFCNames();

      newTestViewImpl.setVisible(true);

      System.out.println("setup test case");

   }

 

   protectedvoid tearDown()throws Exception {

      newTestViewImpl =null;

      TestHelper.cleanUp(this);

      super.tearDown();

      System.out.println("setup test case");

 

   }

   publicvoid testUI() {

      System.out.println("start testing ok button......");

      NamedComponentFinder finder = new NamedComponentFinder(

             JComponent.class,"SubmitButton");

      JButton submitButton = (JButton) finder.find(newTemplateViewImpl, 0);

      assertNotNull("Could not find the submit button", submitButton);

 

      finder = new NamedComponentFinder(

             JComponent.class,"CancelButton");

      JButton CancelButton = (JButton) finder.find(newTemplateViewImpl, 0);

      assertNotNull("Could not find the cancel button", CancelButton);

      

      finder = new NamedComponentFinder(

             JComponent.class,"testNameField");

      JTextField testNameField = (JTextField) finder.find(newTestViewImpl, 0);

      assertNotNull("Could not find the cancel button", templateNameField);

      

      newTestViewImpl.setTestName("mTestName");

      assertEquals(testNameField.getText(), "mTestName");

//    System.out.println(text);

      testNameField.setText("");

      assertEquals("Test field is not null","",newTestViewImpl.getTestName());   

      

   }

   publicstatic Test suite() {

      returnnew TestSuite(NewTestViewImplTest.class);

   }

 

   publicstaticvoid main(String args[]) {

      junit.textui.TestRunner.run(suite());

   }

 

}

4.        Run JFCUnit test case using eclipse plug-in Junit Runner to load testcase and run.
