Hi,
I have just started using jWebUnit yet I am already convinced that it's
a great tool since it's really easy to use and does exactly what I want.
Having said that, unfortunately I have a little problem. Some of my
tests have to run concurrently, yet this causes exceptions. The odd
thing is, it's not always happening, yet quite often.
Basically I have a number of threads that use a webTester to login to a
web application and then click on some links. Nothing fancy. The problem
seems to appear when accessing the TestingEngine:
java.lang.NullPointerException
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Class.java:164)
at
net.sourceforge.jwebunit.TestingEngineRegistry.getTestingEngineClass(TestingEngineRegistry.java:55)
at
net.sourceforge.jwebunit.WebTester.initializeDialog(WebTester.java:74)
at net.sourceforge.jwebunit.WebTester.getDialog(WebTester.java:59)
at net.sourceforge.jwebunit.WebTester.beginAt(WebTester.java:152)
at
com.test.ConcurrentAccessTest$DemoUserThread.runTest(ConcurrentAccessTest.java:54)
at
net.sourceforge.groboutils.junit.v1.TestRunnable.run(TestRunnable.java:154)
at java.lang.Thread.run(Thread.java:595)
Here a snip of my testing code (around line 54):
45: public DemoUserThread(String[] user){
46: this.user = user;
47: this.active = true;
48: this.webTester = new WebTester();
49:
this.webTester.setTestingEngineKey(TestingEngineRegistry.TESTING_ENGINE_HTMLUNIT);
50:
this.webTester.getTestContext().setBaseUrl(TestingConstants.BASE_URL);
51: }
52:
53: public void runTest(){
54: this.webTester.beginAt("/login.jsp");
55: // fill in info
56: this.webTester.setTextField("loginForm:accountInput",
this.user[0]);
Any idea why this is happening?
Regards,
Tom
