PayPal roundtrip sandbox testing - paypal

Question

I am looking for a way for the PayPal sandbox for a round trip test:
create a payment and redirect the user to PayPal so he can log in and approve
user follow the redirect and log in and approve the payment
verify payment on shop side
The steps 1. and 3. are not the problem. But how can I approve the payment automatically in the sand box. IMHO this is a scenario which every developer should need for automatic regression testing but I could not find any solution.
I use Java JUnit for regression tests.
I have tried with WebClient, but PayPal nags about cookies and JavaScript. So I got no success with that.

Answer 1

With the following code I could log in into PayPal developer page. Maybe for someone else this is useful.
package paypaltest;
import java.io.IOException;
public class htmlUnitTest extends TestCase {
#Test
public void test() {
final WebClient wc = new WebClient(BrowserVersion.FIREFOX_10);
wc.getCookieManager().setCookiesEnabled(true);
wc.setJavaScriptEnabled(false);
wc.setWebConnection(new TestHttpWebConnection(wc));
try {
final HtmlPage page = wc.getPage("https://developer.paypal.com/");
System.out.println(page.asXml());
final List<HtmlAnchor> anchors = page.getAnchors();
HtmlAnchor loginAnchor = null;
for (final HtmlAnchor htmlAnchor : anchors) {
if (htmlAnchor.getHrefAttribute().startsWith("https://www.paypal.com/webapps/auth/protocol/openidconnect/v1/authorize?client_id")) {
loginAnchor = htmlAnchor;
break;
}
}
if (loginAnchor != null) {
System.out.println("### login anchor");
System.out.println(loginAnchor.asXml());
System.out.println("### login to: " + loginAnchor.getHrefAttribute());
final HtmlPage loginPage = wc.getPage(loginAnchor.getHrefAttribute());
System.out.println("### login page");
System.out.println(loginPage.asXml());
final HtmlForm loginForm = loginPage.getForms().get(0);
final HtmlInput email = loginForm.getInputByName("email");
final HtmlInput password = loginForm.getInputByName("password");
final HtmlInput login = loginForm.getInputByValue("Log In");
email.setValueAttribute("my#email.com");
password.setValueAttribute("password");
final HtmlPage loggedInPage = login.click();
System.out.println("### logged in page");
System.out.println(loggedInPage.asXml());
}
final HtmlPage pageLoggedIn = wc.getPage("https://developer.paypal.com/");
System.out.println("### page logged in ");
System.out.println(pageLoggedIn.asXml());
