python unittest count tests

Question

Is it possible with unittest to have an option tou count the number of total test number of skipped tests and number of run. And after the run the number of test failed (I know that it can be seen in the output). I would like to dump it in a json if I wan take it programatically that would be great

Thx a lot

After many trials and errors, I finally got this working...

Based on scoffey's answer.

Hope it helps.

import unittest

class MyTest(unittest.TestCase):

    currentResult = None # holds last result object passed to run method

    @classmethod
    def setResult(cls, amount, errors, failures, skipped):
        cls.amount, cls.errors, cls.failures, cls.skipped = \
            amount, errors, failures, skipped

    def tearDown(self):
        amount = self.currentResult.testsRun
        errors = self.currentResult.errors
        failures = self.currentResult.failures
        skipped = self.currentResult.skipped
        self.setResult(amount, errors, failures, skipped)

    @classmethod
    def tearDownClass(cls):
        print("\ntests run: " + str(cls.amount))
        print("errors: " + str(len(cls.errors)))
        print("failures: " + str(len(cls.failures)))
        print("success: " + str(cls.amount - len(cls.errors) - len(cls.failures)))
        print("skipped: " + str(len(cls.skipped)))

    def run(self, result=None):
        self.currentResult = result # remember result for use in tearDown
        unittest.TestCase.run(self, result) # call superclass run method

    def testA(self):
        self.assertTrue(True) # succeeds

    def testB(self):
        self.assertTrue(False) # fails

    def testC(self):
        self.assertTrue(1 + None is None) # raises TypeError

    @unittest.skip("skip it") # skipped
    def testD(self):
        self.assertTrue("whatever")

if __name__ == '__main__':
    unittest.main() 

run script with

python test.py > result.txt

result.txt:

tests run: 3
errors: 1
failures: 1
success: 1
skipped: 1

I'm not sure this is the best way, but it's working. Unittest module is easy to use but hard to master, now I feel I know little about it.
