I am currently trying to repair some old tests (which I did not
even write myself) based on AbstractWicketTest and WicketTester.
At the moment all tests derived from AbstractWicketTest or using
TestNGWicketTester fail with some exception inside Wicket.
Since I am rather unfamiliar with the wicket test infrastructure,
I'd like to ask here, if the stuff below rings any bell with
anyone of you? This second class of exceptions I get seems to
be related to the fact that in our application all CSS and
Javascript includes are handled by a ConcatBundeResource. At
least that's the one where the test code crashes with an NPE.
Again, the test is real simple, it consists of rendering a page
and checking for exceptions etc., this is the code:
| public void setUp() {
| this.tester = new TestNGWicketTester( new MyApplication() );
| }
| public void testRender() {
| this.tester.startPage( ResetPasswordPage.class );
| this.tester.assertRenderedPage( ResetPasswordPage.class );
| }
And the exception I am getting is the following:
[testng] Caused by: java.lang.NullPointerException: null

The 'offending' code in ConcatResourceBunde looks like this:
| private byte[] readAllResources(List<IResourceStream> resources)
throws IOException,
| ResourceStreamNotFoundException
| {
| ByteArrayOutputStream output = new ByteArrayOutputStream();
| for (IResourceStream curStream : resources)
// This is line 169, where the NPE occurs!
| IOUtils.copy(curStream.getInputStream(), output);
|
| byte[] bytes = output.toByteArray();
|
| if (getCompressor() != null)
| {
| String nonCompressed = new String(bytes, "UTF-8");
| bytes =
getCompressor().compress(nonCompressed).getBytes("UTF-8");
| }
|
| return bytes;
| }
Cheers,
M'bert
