Yes it's an idea, some of the settings can be transferred from the
constructor to the setUp method, but that is not the case with the one i
talked about.
A parameter is given to the constructor and the constructor sets a field
with this parameter, and the setUp method cannot accept parameters.
The parameter is given to the constructor when the testSuite is built,
and then only the instance of the TestCase knows the parameter. Anyway,
I can't find a solution to guess this parameter in a fonction without
argument (but continuing to search).

To fix this you can do all the setting that you make in the
constructor in the setUp method.
Nicolas,
2005/8/2, Romain Thouvenin <[EMAIL PROTECTED]>:
I'm now sure this is linked to double instance of test cases : when i
printed a debug message in the MyTestCase(String theName) constructor,
it appeared in the server console whereas it did not use it to build
testSuites.
Cactus does not make an exact copy of the test case, and thus a bad copy
which results in an NullPointerException.
Except from correcting Cactus, I'm completely unable to find a solution
to my problem... *gasp*

I'm creating a tool to launch tests based on cactus.
It uses my own test cases which extend ServletTestCase, and these
testCases have a field used in test methods.
But when i launch the test and try to access this field in the setUp
method, i get a NullPointerException.
I've checked with prints and with a debugger, the field is correctly
initialized.
I've read that cactus make two instances of test cases. Could it be
linked to my problem ?
How are initialized class varaibles when a second instance of the test
case is made ?
To build the TestSuite, i use my own constructor with a code like this :
# suite.addTest(new MyTestCase("testName", MyClass param));
and a field of MyTestCase is directly set with param.
I use cactus 1.7, junit 3.8.1 and orion server 2.0.5
Here is the stack trace

ClientTest.java:77 and around :
#protected void setUp () throws Exception {
# StartSessionServlet sss = new StartSessionServlet();
# sss.init(super.config);
# if(super.getInstance() == null) {
# System.out.println("instance est null"); //This message
is printed in the server console
# }
# try {
# UserInfoBean uib = CollaborateurRep.getInstance().connect(
# super.getInstance().getColLogin(),
super.getInstance().getColPass()); //line 77
# super.getInstance().setUiBean(uib);
I would be glad to give further informations. I did not provide more
java code since it's quite intricate and it would need more
informations, but I'm sure super.instance should be not null (it is
initialized in constructor and then just accessed with getInstance)
Anyway, could I have more accurate information about the way Cactus
instanciate the test case a second time ?
Thanks for your help.
