Inconsistent code coverage shown for LogicalPreparedStatement40

      Description

      I tried running org.apache.derbyTesting.functionTests.tests.jdbc4.PreparedStatementTest with a connectionCPDecorator in a JDBC4 environment. So this should actually run the test with LogicalPreparedStatement40 statements.

      But in code coverage report methods such as setNClob show no coverage in LogicalPreparedStatement40 class. But in PreparedStatement40 class all these methods are shown as covered. Actually those method calls should go to PreparedStatement40 through LogicalPreparedStatement40. But it is not shown in emma code coverage report.

        That's very odd...

        I applied your patch and added
        System.out.println("I AM CALLED!");
        at the beginning of LogicalPreparedStatement40.setNString() before I ran the emma-single target. I saw that "I AM CALLED!" got printed to the console, but the EMMA coverage report claimed that setNString() hadn't been called.

        So it would look like an EMMA bug. However, I ran the same experiment with JaCoCo (ran the jacoco-junit-single target instead of emma-single) and got the exact same results: "I AM CALLED!" was printed, but the coverage report said the code wasn't exercised.

        It must be something our tests do that confuses the code coverage tools, but I don't know what it could be.

        Indeed that is very strange.

        Actually I saw similar kind of behaviour in LogicalCallableStatement and LogicalCallableStatement40 also, where no coverage is shown for some methods although the methods seem to be called by the tests.

        Are these classes dynamically loaded? Is it possible that dynamically loaded classes aren't measured correctly by the code coverage tools?

        You could try increasing the Emma logging level: http://emma.sourceforge.net/faq.html#q.verbose
        to see if there is a warning from the Emma libraries that perhaps we are overlooking?

        org.apache.derbyTesting.junit.JDBCDataSource does some class loader magic in its getDataSourceObject() method, which is where the ConnectionPoolDataSource instance is created by the test framework. Not sure if that could cause any confusion. (I'm not even sure why the class loader magic is needed. Perhaps it's there to support the upgrade tests, where we need to load a different version of the data source class than the one found on the system class path?)

        I tried running 'ant -verbose' to see if I could better understand how the emma-single
        target works. I've pasted the output of the instrumented JUnit invocation below.

        It's interesting, to me, that we appear to have both sets of Derby classes in the
        classpath: the instrumented derbyrun.jar comes first, and then my normal sane jars
        come afterward (although derbyTesting.jar comes before the instrumented derbyrun.jar)

        Is this how it is supposed to look? Or should I only have the instrumented derbyrun.jar
        in my path?

        If Bryan's experiment was run with the CLASSPATH environment variable set, the results might be explained by the following comment in the junit-init target:


        The preferences:
        1) User-specified derby.junit.classpath
        2) Jars (insane preferred over sane)
        3) classes-directory

        Note also that the user's CLASSPATH environment variable is appended
        to the JUnit classpath, but in most cases Derby classes here will be
        shadowed by one of the above entries. It is recommended to not have
        any Derby classes in the CLASSPATH environment variable.

        As long as the instrumented derbyrun.jar appears before the other jars, I don't think it should cause any problems, though.

        Indeed, I had CLASSPATH set. Good catch!

        Nufail, here's a few other suggestions that might be worth trying:

        1) Can you identify any pattern in which LogicalPreparedStatement40 methods are
        correctly instrumented, and which are not? Try putting a 'System.out.println' at the
        front of every single method in LogicalPreparedStatement40, so that you can manually
        determine which methods are being executed by PreparedStatementTest, and which are
        not, and then compare your findings with the Emma report to see which methods it's missing.

        2) Once you've done that, try the same thing with JaCoCo. Do both tools miss the same
        set of methods? Or is one tool missing a different set than the other?

        3) We could try asking on either the Emma or JaCoCo lists for suggestions on how to
        diagnose a problem such as this. Perhaps those tools have additional internal debugging
        we can enable, to gather more information about the instrumentation and reporting phases
        to see if we can figure out where the methods are being dropped.

        I tried out the suggestions.

        1) Methods which are not correctly instrumented are those which are implemented in PreparedStatement40. What LogicalPreparedStatement40 does is forward all calls to the underlying physical prepared statement. So those which are implemented in PreparedStatement40 are causing this problem while those in PreparedStatement and Statement classes work fine. Also all those methods in PreparedStatement40 throw exceptions as they are not supported.

        2) Emma and JaCoCo reports are the same. They miss same set of methods.

        3) Siddharth has started a thread on JaCoCo mailing list at https://sourceforge.net/projects/eclemma/forums/forum/614869/topic/5425816

        As one more way to confirm that the problem is directly related to methods which exit by
        throwing exceptions, why don't you try this:

        1) Change one of those PreparedStatement40 methods so that instead of throwing an
        exception, it just prints a message to the screen and returns normally. Also put a print
        message in the LogicalPreparedStatement40 method that calls it
        2) Run the PreparedstatementTest. It should fail, because it expects the method to throw
        an exception. But it should show that both print statements are printed to the screen.
        3) Check the code coverage report. Now it should show that the method is fully covered,
        in BOTH PreparedStatement40 and LogicalPreparedStatement40

        Yes, it does work. The code coverage report shows the method as covered in both PreparedStatement40 and LogicalPreparedStatement40 when an exception is not thrown. So it looks like the problem is related to throwing exceptions. But even when an exception was thrown, method was shown as covered in PreparedStatement40.

        Given what we've learned about the code coverage tools, do we think that this patch
        in fact increases the overall code coverage of our test suites? Or do we now think that
        we were already testing LogicalPreparedStatement40 adequately, and it is just that

        Bryan, I think the wiki pages can be updated with this info. I will look into it.

        Also, I added a connectionCPDecorator to the following tests and they also showed an improvement in code coverage. And it might help to make sure that different statement implementations do not behave differently.
