Generating custom pyunit report

Question

I am trying to generate a custom pyunit test suite execution report, but hitting with a 'no attributue' error.

import json
import unittest
import sys

class MyTestResult(unittest._TextTestResult):
    def addSuccess(self, test):
        TestResult.addSuccess(self, test)
    def addError(self, test, err):
        TestResult.addError(self, test, err)
    def addFailure(self, test, err):
        TestResult.addFailure(self, test, err)

class MyTestRunner(unittest.TextTestRunner):
    def _makeResult(self, verbosity):
        return MyTestResult(self.stream, self.descriptions, verbosity)

class TestServer(unittest.TestCase):
    def testFunction1(self):
        res = True
        self.assertTrue(res, "test case failed")
    def testFunction2(self):
        res = 5
        self.assertEqual(res, 5)
    def testFunction3(self):
        res = True
        self.assertEqual(res, True, 'test case failed')
    def testFunction4(self):
        res = False
        self.assertEqual(res, True, 'test case failed')

# Create an instance of each test case.
testCase1 = TestServer('testFunction1')
testCase2 = TestServer('testFunction2')
testCase3 = TestServer('testFunction3')
testCase4 = TestServer('testFunction4')

# Add test cases to the test suite.
testSuite = unittest.TestSuite()
testSuite.addTest(testCase1)
testSuite.addTest(testCase2)
testSuite.addTest(testCase3)
testSuite.addTest(testCase4)

# Execute the test suite.
testRunner = unittest.MyTestRunner(verbosity=2)
testRunner.run(testSuite)

The error I am getting is below. I also need some help to customize my final test report so that I can add some additional information than the one pyunit generates. What should I implement inside 'MyTestResult' class more?

bash-3.2$ python myreport.py
Traceback (most recent call last):
  File "myreport.py", line 45, in <module>
    testRunner = unittest.MyTestRunner(verbosity=2)
AttributeError: 'module' object has no attribute 'MyTestRunner'

Additionally, I am looking for some suggestion to modify the test report, which is coming as below by default.

bash-3.2$ python myreport.py
testFunction1 (__main__.TestServer) ... ERROR
testFunction2 (__main__.TestServer) ... ok
testFunction3 (__main__.TestServer) ... ok
testFunction4 (__main__.TestServer) ... FAIL

The line should be replaced with:

testRunner = MyTestRunner(verbosity=2)
# To refer your test runner.

There are another issues. Here are updated MyTestResult and MyTestRunner:

class MyTestResult(unittest._TextTestResult):
    def addSuccess(self, test):
        super(MyTestResult, self).addSuccess(test)
    def addError(self, test, err):
        super(MyTestResult, self).addError(test, err)
    def addFailure(self, test, err):
        super(MyTestResult, self).addFailure(test, err)
        # To call parent's method use `super`

        # OR qualify with parent class
        # unittest._TextTestResult.addFailure(self, test, err)


class MyTestRunner(unittest.TextTestRunner):
    def _makeResult(self):
        # _makeResult is not called with verbosity, use `self.verbosity`
        return MyTestResult(self.stream, self.descriptions, self.verbosity)

Using the code as is, I get the following error: File "myreport.py", line 49, in <module> testRunner.run(testSuite) File "/users/anjangam/pyvenv/venv/lib/python2.7/site-packages/unittest.py", line 330, in call test(result) File "/users/anjangam/pyvenv/venv/lib/python2.7/site-packages/unittest.py", line 209, in call result.addError(self,self.__exc_info()) File "myreport.py", line 10, in addError super(MyTestResult, self).addError(test, err) TypeError: must be type, not classobj

Using this line 'unittest._TextTestResult.addFailure(self, test, err)' solves the problem.

@AnilJ, super(MyTestResult, self).add...(test, ...) also should work. I tested both.

For some reason, it throws above error message I pasted.

Any suggestion on how to modify (or replace) the default test report that pyunit tool generates?
