+1 It should be part of the commit acceptance process. Otherwise OpenJPA will loose out to other ORM tools that will be perceived as less buggy. What is used for coverage monitoring, clover? We should also use checkstyle to give some insight into the code as well
Phill -----Original Message----- From: Patrick Linskey [mailto:[EMAIL PROTECTED] Sent: April 9, 2007 12:51 PM To: open-jpa-dev@incubator.apache.org Subject: Unit testing Hi, I'm a bit concerned about the lack of unit tests being put into OpenJPA as new features are added. I understand that often, creating unit tests are anticlimactic compared to implementing the feature itself, but at least basic happy-path testing of new features is pretty essential if we want to avoid these types of problems. Code inspection is good but, Abe's good eyes aside, not as reliable as having a unit test that will start failing when a feature is broken. I try to write my test cases first, in a somewhat-modified TDD approach. I do this because a) I need some sort of harness to demonstrate the failure in order to isolate and resolve it, and b) I know that personally, I'm much more likely to write a test while the problem is still interesting than after it's resolved. In other words, I never (well, rarely) have a command-line harness that I throw together to demonstrate a problem. I try to always use a test case instead. This strategy means that the only test-related overhead is the effort involved to figure out how to programmatically test for failure. Also, I understand that some things are hard to test. Testing SQL or JDBC interactions is often percieved to be one of these things. In the Kodo codebase, we ended up creating various means to get around this; the SQLListenerTestCase is one such example. It turns out that by extending SQLListenerTestCase, it becomes trivial to check how much SQL was written and what the SQL looks like. Does anyone else have any thoughts about how to ensure that we develop test cases as needed? -Patrick -- Patrick Linskey BEA Systems, Inc. _______________________________________________________________________ Notice: This email message, together with any attachments, may contain information of BEA Systems, Inc., its subsidiaries and affiliated entities, that may be confidential, proprietary, copyrighted and/or legally privileged, and is intended solely for the use of the individual or entity named in this message.
