dutest 0.1.1

An object-oriented API to test doctests using unittest runners.

Module providing classes which extend doctest module so as to achieve better integration with unittest.

It is different from the Pyhton 2.4 doctest unittest API because:

• A new unitest.TestLoader descendant now allows to load instances of TestCases for doctests using unittest-style, supports building complex test suites in a more natural way, and eases the use of specialized instances of TestCase built out of doctest examples.

• Other loaders allow users to extract TestCase instances out of TestCase descendants and doctests (and any other format) in a single step.

• In this case unittest.TestResult instances report whether individual examples have been successfully executed, or otherwise have failed or raised an unexpected exception. Formerly TestResult objects contained the whole report outputted by doctest module.

• Test analysis require no further parsing to retrieve detailed information about failures.

• A whole new unittest API for doctest adds object orientation and eliminates functions with big signatures.

• It is not necessary to use DocTestRunner output streams in order to collect test results.

• A new hierarchy of doctest TestCases is now possible so for example, setUp and tearDown may be redefined across a hierarchy of TestCases instead of providing this methods as parameters to a function (breaking OOP philosophy and logic); or maybe even failures and errors can be represented in a custom way.

• Allows to perform regression testing over tests written using doctest.

• Fixes a minor bug related with specifying different verbosity levels from the command line to unittest.TestProgram (alias main).

• Loads by default test cases for doctests plus those formerly loaded by unittest.TestLoader

It is similar to the Pyhton 2.4 doctest unittest API because:

• Provides integration with TestProgram and unittest test runners.

• Allows to parameterize doctest behavior via doctest options
