Mauve coding on Windows

Mauve coding on Windows

[Martin Olsson]

Hi,

I would like to write some test cases for the GNU classpath project. I 
fetched Mauve from CVS (using eclipse "create project from cvs") but I 
ran into a whole bunch of errors:

http://mnemo.minimum.se/error.txt

I think these errors are related to me running Windows 2000 and windows 
does not allow a file called "Color" and a dir called "color".

Someone on IRC said that there is atleast one other guy that uses 
Windows for Mauve development (Jeroen?). If anyone can provide 
information how I can setup a proper Mauve-compatible dev environment on 
Windows please drop me a line.

---

I also have another question, how do I know what test cases are missing 
and needs to be implemented?

As your purpose is to just write some new tests and not to test GNU 
Classpath, the simplest and easiest way would be without much thinking 
to delete all tests.

Store the unmodified copy of the source. Then remove 
'BinaryCompatibility', 'gnu', 'java', 'javax', 'locales' and 'org' from 
gnu/testlet. Try to build. Errors will be reported in 
gnu/testlet/config.java, because the generated file names contain the 
'\' character (separator under Windows!). Open that file and replace the 
'\' by '\\' in all strings. Try to build again. Should succeed. Now, 
look at the contents  the previously deleted gnu/testlet/java, 
gnu/testlet/javax and so on, to see how the tests look like and that 
rules the folder system follows. All tests implement the Testlet 
interface and has the line like "// Tags: JDK1.4" on the top. The Mauve 
framework is rather clear, you will understand. Try to move back, 
compile and run several tests that would look simple for you.

If still fails, check:

1. If Eclipse has copied all source files into the project folder in 
workspace.
2. If your Ant is properly installed and added to the project build path.

I think you misunderstood; I actually intend to write tests for GNU 
classpath.

Re: Mauve coding on Windows

No, I understand. You want to contribute to GNU Classpath project by 
writing new Mauve tests. But just for this you do not need to run all 
EXISTING Mauve tests. The existing tests are used to ensure that the new 
changes in GNU Classpath library itself do not introduce regressions, 
that nothing is spoiled while improving another part. You can write and 
run your tests on Sun's jre even without trying to build Classpath 
itself. After you commit them to CVS, others will run them on Classpath 
and use the results of your tests..

Of course, it is worthwhile to learn how to to run a complete Mauve test 
set, and how to build Classpath, and join the main project developing 
and so on. All this would be great from your side, but it takes time and 
may not be easy under Windows. The new Mauve tests are very important 
for us; our coverage is still not sufficient. There are still several 
important packages where no single class is covered. You told me you 
want to join us by writing new Mauve tests, I explained how to set up 
the developing platform in the fastest possible way.

Regards.
Audrius.

It won't be easy to run all the tests on Windows initially, but I think 
if we can solve the problem of checking out the CVS into Eclipse on 
Windows, it won't be long before someone writes a utility to make it 
simple to compile and run all (or a selected subset of) the tests.  And 
if the end result is more developers working on Mauve, then I think it 
is worth the effort.

Re: Mauve coding on Windows: The majority of tests runs under Windows.

[Meskauskas Audrius]

I have tried to put the Mauve tests back after setting up it with 
Eclipse under Windows. The most of the tests work, despite some need jdk 
1.5 to compile and a couple hangs after printing the message about the 
uncaught exception. Strange, I do not get any of Martin's error messages.

I would really much rater be able to runs all the tests too and they 
would also be good for reference when I need to check how some problem 
was solved earlier. And in the long run I'm hoping that my contribution 
to Mauve will enable me to learn more about the classpath project so 
that I will be able to contribute to the actual classpath code later.

When and if someone fixes the naming problems you got atleast one more 
developer going into the project; me.

If my Eclipse error log is complete it's a matter of renaming at a very 
minimum say 25 files (or the corresponding dirs ofc). But it would be 
much nicer to have a consistant naming for the entire directory 
structure. I would definately vote for renaming the classes that test 
class Xxxx to XxxxClass instead of Xxxx_ because I think the first name 
is more descriptive and would confuse mauve newcomers less.

Good, let's do it.

I'd say, go with XxxClass to rename the classes, rather than 
packages/directories. Can you send in a patch?

As for consistency, I guess one could spend a lot of time arguing for 
the most consistent naming of all the test cases, but ... let's just 
leave it as it as long as no pressing reason comes up, and do the 
minimally invasive thing. When someone wants to check out mauve on a DOS 
FAT file system, we can worry about the 8+3 naming limitations then, for 
example.

I ran into the same problem a while back when I was stuck with a Windows 
machine for a week.  Perhaps we could resolve it by renaming the Color 
directory (containing tests for the Color class) to 'ColorClass' or 
'Color_'?  And the same for any other name clashes (e.g. Font and font).

For the majority of the tests, the test class name matches the name of 
the method it is testing.  So scanning the source tree is one way to see 
which methods have (at least some) tests.

There is also a utility in CVS for generating some HTML pages for the 
results of a Mauve run:

gnu.testlet.runner.Mauve

These pages are organised by package/class, so that is another way to 
see the existing coverage.

Well, this should be pretty easy to fix by renaming a few files.  This
would be a good patch for Mauve.

I created Eclipse project from existing Mauve sources using "New -> Java 
project from existing Ant build file". Then the build is initiated as 
"Run as -> Ant build" in the context menu on build.xml in the Package 
Explorer view.

Mauve is already set up in Eclipse as a plain old java project, where
the internal eclipse builder is used.  I think this is preferable as
it yields a nicer development environment...

Also in my setup, the mauve project depends on having a Classpath
project in the same workspace, the idea being that mauve will be built
against the just-built Classpath.  I also have it depending on a jamvm
project, to make it really easy to run mauve against classpath from
inside Eclipse.  I haven't checked this part in yet.

Yes, of course, but the primary idea was to have all this running under 
Windows. You
are probably talking about the Linux environment.
