I am trying to follow Michelle's instructions and writing a test case for Sequence Assertions. I have the following question:
1. What package should i put my Test Case in?
The first question is whether the test cases are their own group or fall into another category. Since you obtain a Sequence via pm.getSequence, you might argue the tests belong in org.apache.jdo.tck.api.persistencemanager. But most of the assertions regard the behavior of the sequence itself, which argues for org.apache.jdo.tck.api.sequence as the package. But how many independent test cases are there? If only a few, it might be just one test case in which case the api.persistencemanager package TestSequence.java would suffice.
2. Which .jdo file should i add the <sequence> element to?
Probably it belongs in the standard .orm files (mapping=0) for datastore sequences, and in the .jdo file for factory sequences.
3. I have specified my own .conf file, below are the contents of that file:
-------aaa.conf------------------------------------------
jdo.tck.description = Run one test for debugging
jdo.tck.testdata =
jdo.tck.standarddata =
jdo.tck.mapping = 0
jdo.tck.classes = org.apache.jdo.tck.api.persistencemanager.Test # Change the name of the class once the Test Case runs successfully
--------------------------------------------------------------------
As you can see from above, i was trying to run the Test Case so i temporarily made a Test Case named "Test" and put it in package org.apache.jdo.tck.api.persistencemanager. Then i inserted the <sequence> element in
/test/applicationidentity/jdo/org/apache/jdo/tck/pc/company/package.jdo.
This probably belongs in the .orm file unless you are defining a factory sequence that you have implemented.
*** For factory sequences (not defined in the database) is the API sufficient to use the sequence in the three modes: nontransactional, contiguous, and noncontiguous? ***
<sequence name="TestSequence" datastore-sequence="TEST_SEQ" strategy="contiguous"/>
This needs to be contained in a package element, presumably package name="org.apache.jdo.tck.pc.company". But you have named a datastore sequence, TEST_SEQ, that has to exist in the database. You need to define it in the schema file.
*** Does Derby support sequences? ***
--------------Below is my test() method.---------------------
public void test() {
pm = getPM();
Transaction tx = pm.currentTransaction();
tx.begin();
Sequence seq = pm.getSequence("org.apache.jdo.tck.pc.company.TestSequence");
//
// fail(ASSERTION_FAILED,
// "Expected a sequence named org.apache.jdo.tck.pc.company.ProductSequence but got null instead");
//
tx.commit();
pm.close();
pm = null;
}
---------------------------------------------------------------
When i run the test i get the following error (I know i am testing for this error if sequence not found, i just want to make sure i am doing stuff properly):
[java] 1) test(org.apache.jdo.tck.api.persistencemanager.Test)javax.jdo.JDOUserException: The requested sequence "org.apache.jdo.tck.pc.company.ProductSequence" could not be found. Please mak
sure that it is specified in a valid Meta-Data file.
Maybe this is due to not putting the sequence inside a package element? Or because the TEST_SEQ database sequence is not defined?

Michelle: One issue here is that your instructions say that i should invoke maven -Djdo.tck.cfglist=aaa.conf installSchema first. If i do that with a mapping of jdo.tck.mapping=0, then it takes a long time to install the schema.
You only need to do that if you change the schema file. Once defined, you don't do it again until you add more schema.
Do we really need to installSchema everytime for the value 0. In my case, i am simply trying to test pm.getSequence("org.apache.jdo.tck.pc.company.TestSequence"), can i simply put a jdo.tck.mapping = 1 instead?
An early response would be appreciated
I've copied the expert group who might be able to help with some of your questions.
