[Jython-users] Possibly FAQ re Junit

From: Dave D. <d.j...@hu...> - 2002-03-22 10:14:26

Dear All,
I have searched the archives and posted on the Junit list.
No definitive answer, so trying again. ;)
I have been using unittest with Jython but would like to use JUnit
for teaching/illustrative purposes. The maillings suggest that use
of JUnit and automatic suite generation is problematical due to reflection.
I have tried using docstrings and jythonc but without much success.
Does there exist a port of the JUnit distribution demo ( Money ) in
jython that successfully works with GUI runner that I can use as a
leg-up ?
	Many thanks
	David

[Jython-users] IPC

From: Stephen N. <ste...@co...> - 2002-03-22 15:29:26

I have a system made up of two parts.  One in Jython and the other in
CPython.  The reason for this is that I could not find a Gnutella
library in CPython, but I could in Java.  Also I have been having
difficulties with BerkeleyDB Java bindings, so I decided to use 
CPython's bsddb.

Anyway, I would like the jython and python processes to communicate with
each other.  I was think of IPC using scokets, but I'm not sure if this
is the best option.

I'd be grateful for any advice on this as I have not done this sort of
thing before.  Alternatively if anyone knows of a good python gnutella
library (like Jtella), that would be an alternative solution.

Thanks Again.

Stephen

I have a CPython system (Zope) talking to a Jython system via xml-rpc.
 
xmlrpcserver.py can be found at:

http://www.pythonware.com/products/xmlrpc/index.htm

it works fine in jython.  Note, xml-rpc will only give you simple data

pasing, numbers, strings, lists, "structs" etc.

You have several options, ranging in rough order of difficulty:

- Python-specific RPC technology (PYRO http://pyro.sourceforge.net/ or 
DOPY http://www.users.cloud9.net/~proteus/dopy/)
    I actually haven't used either, as I've needed cross language 
interoperability, but I probably would use one of them if I were doing 
all-Python RPC

- Python-based CORBA solution (Fnorb or omniorb and possibly Java's 
CORBA interfaces)

- XML-based RPC technology (xmlrpc/soap) (haven't done much with these)

- custom sockets (probably using pickles, maybe SimpleTCPServer or 
BaseHTTPServer)

- some other communication mechanism you dream up - write to a file, 
database, etc.

In spite of what RPC vendors would have you think, none of this is very 
difficult, and unless you
have significant stability or performance requirements, all should be 
quite suitable.  I imagine that
if PYRO or DOPY works for you, they will be significantly easier than 
any of the others, but all
the others are pretty similar in difficulty.

IMO, YMMV, etc.

[Jython-users] pydoc for jython?

From: Eric B. <EBi...@sa...> - 2002-03-27 00:44:42

I want to generate HTML documentation for my Jython modules ala `pydoc -w`
for CPython. Pydoc doesn't work for me because "import java" fails under
CPython. The best docstring HTML generator I've yet found for Jython is
HappyDoc (http://happydoc.sourceforge.net/). What other alternatives are out
there?

One more I forgot to mention, which may be suitable for your application:

If you are going to have one of your processes spawn the other, you can 
just use os.popen* (in CPython) or Java's Runtime.exec (in Jython until 
I or someone else implements popen* functions) to spawn the child 
process. The parent then reads from/writes to the returned file handles, 
and the child reads/writes stdin/stdout.

Hello Dave,

not sure if this is what you are looking for:
We extended JUnit in a way that we can use the normal ui (gui or text)
to run our tests, but the tests themselves are written in Jython. One
advantage of this is (in addition to all other advantages of Jython
versus Java) that we can unit test both Java and Jython classes in the
same framework.

There was a small change necessary to the getTest() method in the
junit.<any>ui.TestRunner classes:
If a Jython unit test should be found, use a custom test finder to
locate the .py file containing the test.
The Jython test class extends junit.framework.TestCase (and therefore
implements junit.framework.Test).
The trick is to use embedded Jython to be able to return a
junit.framework.Test object to the TestRunner.

This way we can use the whole junit framework to run Jython unit tests
behaving like normal java unit tests.

Hopefully this gave you an idea.

Best wishes,
Oti.

Hi Dave: I manage an open source project called TestMaker (formerly Load)
that builds intelligent test agents to assure Web Services (HTTP, HTTPS,
SOAP, .NET, etc.) for functionality, scalability and performance. TestMaker
embeds Jython as a scripting language to drive a library of test objects.
You may find it to be a good compliment to Junit.

About your question on learning materials, take a look at:
http://www.pushtotest.com/ptt/thekit.html

This is a knowledge kit I put together for BEA that shows how to set-up a
SOAP-based Web service and test it using TestMaker. The kit comes with an
article and all the source code. You're welcome to use it as courseware.

-Frank
