Hi all.

I would like to change the way test reports are generated, in a Zope
environment.

I'm playing with TextTestReport, TextTestRunner. Since things are
getting to complicated, I'm afraid I'm following a non-pythonic way.

Specifically, I would like to have an output like:

package.subpackage.test_module.TestCase 0.1

where 0.1 is the time spent into doing the test.

In a previous attempt, I made the tests print the number of the test
executed, so that I would have the following output:

1 package.subpackage.test_module.TestCase

however, to do this, I had to put things in the following way:


class PAFlowTestRunner(TextTestRunner):
def _makeResult(self):
return PAFlowTextResult(self.stream, self.descriptions, self.verbosity)

class PAFlowTextResult(_TextTestResult):

def startTest(self, test):
self.stream.write("%s " % self.testsRun)
_TextTestResult.startTest(self, test)


now, of course, this is ugly, because I'm using _TextTestResult, which
I'm not supposed to know, and I'm changing behaviour by subclassing,
which is not exactly what I would like to do.

What is the pythonic way to accomplish this?

Have you looked at nosetests? Nose is a test-discovery & running-framework
based upon unittest-module (but you can also "only" test simple functions,
very handy)

And it has a very powerful plugin-mechanism, that allows you to implement
cleanly what you want.

For each test, you get a start/end-method called in your plugin that you can
use to gather the information you need, e.g. start/stop-times.

For example, I've created an enhanced reporting plugin that lists all tests
run (not only those failed or error'ed), and adding time-measuring per-test
is on my list of todos.

Nope; next time I will make a google search before posting

I gave it a look; it is nice and it seems powerful; I just wonder if I
need to put my hands on all my tests to do what I want to do... but
I'm sure this can be sorted in the documentation.

Looks like there is a new tool I need to learn... ah, nice times when
all you needed was an hammer and a screwdriver...


Thanks for the suggestion, Diez, I'll read it.
