Running Tests

Hi all,

I'm working on improving the Cache Manager. I have a working trunk copy. I can
run the ij tool and create/access databases. I want to run some tests to verify
my new implementation. I saw that there were some unit tests for the cache
service but I can't seem to get it running properly. The error says that a
certain Class is not found UnitTestMain (I think). The wierdest thing is that I
can run the RunTest class so I'm pretty sure that UnitTestMain should be found.

In addition, when I make the derbyTesting package, I get several errors when
compiling JDBC related files.

Can someone point me to documentation on how to get the tests running? I don't
need to run all of them. Just testing the cache service is enough for now.

Thanks,

Gokul

You should also check that you have built all the test-classes:
What is the output of:
ls $DERBY_HOME/classes/org/apache/derbyTesting/unitTests/harness/

If there is no UnitTestMain.class in that directory, try to compile the 
tests with:
ant all

.. and since you have had compile problems, try to compile it from scratch:

ant clobber all buildjars

It seems correct, however it seems to not all classes have been compiled.

Hi Myrna,

I can confirm that you found the problem, and that your suggestion works.

CLASSPATH=$DERBY_HOME/classes:$DERBY_HOME/tools/java/junit.jar:$DERBY_HOME/tools/java/jakarta-oro-2.0.8.jar 
java -Dframework=DerbyNetClient 
org.apache.derbyTesting.functionTests.harness.RunTest unit/cacheService.unit

I was just trying to figure this out myself, because I didn't see the 
reported failure as I run my tests with a script (which sets environment 
variables).

Thanks for giving us the solution :)

I meant, add the following to the environment variable $CLASSPATH.
(not just an environment variable) :
"$DERBY_HOME/classes:$DERBY_HOME/tools/java/junit.jar:
$DERBY_HOME/tools/java/jakarta-oro-2.0.8.jar"

Hi Gokul,

The test harness spawns off further java processes which may not
inherit the classpath if you use -cp. Please see what you get when you
add the classes dir, junit.jar and jakarta jar to an environment
variable, then run the test.

Hi Kristian,

Sorry for the late reply. I noticed that my code had some problems that wouldn't
allow me to run unit tests. Hopefully, all bugs are fixed now.

You were correct. JUnit was the problem and now the compile time errors are
gone. I think I may be running the test incorrectly. I have posted the command
that I use:

java 
-cp $DERBY_HOME/classes/:
$DERBY_HOME/tools/java/junit.jar:
$DERBY_HOME/tools/java/jakarta-oro-2.0.8.jar 
-Dframework=DerbyNetClient 
org.apache.derbyTesting.functionTests.harness.RunTest unit/cacheService.unit

With this, I get the following error:
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/derbyTesting/unitTests/harness/UnitTestMain

Can you confirm/correct the way I'm running the test?

Thanks,

Gokul

Hello Gokul,

The errors you are getting seem related to JUnit.
What version of JUnit have you put in your $DERBY_HOME/tools/java? Derby 
is using 3.8.1. Don't know how far you get if you are using 4.1 instead.
Also, the file BaseJDBCTestCase should be in 
testing/org/apache/derbyTesting/functionTests/util. I guess 
ScrollResultSetTest is extending this class.

According to the JUnit (v. 3.8.1) JavaDoc, the methods that cause 
compilation errors are valid members of the Assert class. Verify that 
the junit.jar file is valid/working.
You should be able to build the classes in java/testing by doing 'ant 
testing' from $DERBY_HOME, and if you are using jars you must also 
remember to build the testing jar.

I can also confirm that I was able to compile Derby and run the test 
unit/cacheService.unit with revision 418240.

I get the similar errors in the testing files only for files in the directory,
org/apache/derbyTesting/functionTests/tests/jdbcapi/. The files mentioned in my
earlier post, BaseJDBCTestCase and ScrollResultSetTest are in this directory.

Same errors.

Thanks for your help.

Do you get the errors if you do "ant all"?

What happens if you try to run class files in your classpath instead of 
jars?  (i.e, CLASSPATH=$DERBY_HOME/classes)

Hi Andrew,

Thanks for your help.

I'm using this document as a guide.

I'm running ant inside java/testing/. I get 2 sets of compile time errors:

1. 1st set related to BaseJDBCTestCase with method assertTrue()
2. 2nd set related to BaseJDBCTestCase.java/ScrollResultSetTest.java with
methods assertEquals(), assertTrue(), and assertFalse()

These errors seem related. Also, I get the same errors if I build from
${derby.home} by running "ant testing". Please see below for the error printouts.

To run the tests, I wrote a script which runs sysinfo first and then the
cacheService unit test. It doesn't run any tests. I get the error message:
 Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/derbyTesting/unitTests/harness/UnitTestMain

For more details and error messages, please see below.

Gokul

The testing readme is in java/testing/README.htm.

If you post the errors you are receiving at compile time and run time,
I can help you track the problem down further.
