Automated tests

JxBrowser API provides a lot of features that can be used for writing automated tests and simulating user activity on a web page.

Overview

Using JxBrowser API you can:

Load URL, HTML from string, local file including PDF documents.
Access JavaScript Console to read all log messages.
Access JavaScript on the loaded web page and execute any JavaScript code.
Access DOM of the loaded web page. Read and modify DOM HTML elements.
Access and modify cookies.
Access and modify HTTP request/response headers on the fly.
Using remote debugging port (--remote-debugging-port=9222) you can attach to JxBrowser from Google Chrome to debug JavaScript on the currently loaded web page.
Handle JavaScript dialogs such as alert, confirmation, prompt.
Configure Proxy settings per Engine instance and more.

Example

The following example demonstrates how to programmatically log in to Facebook using specific credentials:

import static com.teamdev.jxbrowser.engine.RenderingMode.HARDWARE_ACCELERATED;

import com.teamdev.jxbrowser.browser.Browser;
import com.teamdev.jxbrowser.dom.Document;
import com.teamdev.jxbrowser.dom.Element;
import com.teamdev.jxbrowser.dom.FormControlElement;
import com.teamdev.jxbrowser.dom.Node;
import com.teamdev.jxbrowser.engine.Engine;
import com.teamdev.jxbrowser.frame.Frame;
import com.teamdev.jxbrowser.view.swing.BrowserView;
import java.util.Optional;
import javax.swing.JFrame;
import javax.swing.SwingUtilities;

public final class FacebookLogin {

    public static void main(String[] args) {
        var engine = Engine.newInstance(HARDWARE_ACCELERATED);
        var browser = engine.newBrowser();

        SwingUtilities.invokeLater(() -> {
            var view = BrowserView.newInstance(browser);

            var frame = new JFrame();
            frame.add(view);
            frame.setSize(800, 600);
            frame.setVisible(true);

            // Load Facebook login page and wait until it is loaded completely
            browser.navigation().loadUrlAndWait(
                    "https://www.facebook.com/login.php");

            // Find and enter email
            findElementById(browser, "email").ifPresent(emailElement ->
                    ((FormControlElement) emailElement).value("user@gmail.com"));
            // Find and enter password
            findElementById(browser, "pass").ifPresent(passElement ->
                    ((FormControlElement) passElement).value("123"));
            // Find and click the Login button
            findElementById(browser, "loginbutton").ifPresent(Node::click);
        });
    }

    private static Optional<Element> findElementById(Browser browser, String id) {
        var mainFrame = browser.mainFrame()
                .orElseThrow(IllegalStateException::new);
        var document = mainFrame.document()
                .orElseThrow(IllegalStateException::new);
        var documentElement = document.documentElement()
                .orElseThrow(IllegalStateException::new);
        return documentElement.findElementById(id);
    }
}

UI test automation

JxBrowser is compatible with different UI software testing tools that let you build a test suite for your entire application UI.

QF-Test

If you prefer a GUI solution including Record & Replay functionality, we recommend using the professional UI software testing tool QF-Test (by QFS). With QF-Test’s intuitive user interface you can build a test suite for your entire application UI including any embedded JxBrowser instances.

QF-Test Automated Tool

QF-Test handles all the communication with the JxBrowser API for you, leaving you to concentrate on meeting your testing requirements.
