Using docstring for Testing Good Python includes docstrings inside every module, class, function, and method. Many tools can create useful, informative documentation from the docstrings. How can we turn examples into proper test cases? Let's explore this question. • Put examples into docstrings and run the doctest module as a program • Write examples for the Stateless and stateful functions Testing Functions that Raise Exceptions This video will show you how to turn exception processing and the resulting traceback messages into proper test cases. • Create a global __test__ variable in the module • Include the invocation with a doctest directive comment, IGNORE_EXCEPTION_DETAIL • Include an actual traceback message and test the entire module's features Handling Common doctest Issues Doctest examples require an exact match with the text. How can we write doctest examples that handle hash randomization or floating-point implementation details appropriately? This video will enable you to answer this question. • Write Doctest examples to map or set values • Write Doctest examples for floating point values Creating Separate Test Modules and Packages This video will show you how you could create more sophisticated tests. • Define a setUp() method in this class to handle the Given aspect of the test • Define a runTest() method to handle the When aspect of the test • Add assertions to implement the Then aspect of the test Combining the unittest and doctest Tests This video shows how we can combine all of the various tests into one tidy package. • Import the module which is being tested • Implement the load_tests protocol • Use the doctest.DocTestSuite class to create a suite Testing Things that Involve Dates and Time Many applications rely on datetime.datetime.now() to create a timestamp. When we use this with a unit test, the results are essentially impossible to predict. How can we work with datetime stamps? Let's look into this. • Include the code to be tested and create the skeleton for testing • Use the setup() and runTest() methods Testing Things That Involve Randomness Many times we create random values or put values into random order. In many statistical tests, repeated random shuffling or random subset calculations are done. Let's see how we can unit test algorithms that involve randomness. • Define an outline of the overall test class and a mock version of the random.choice() function • Define the When and Then aspects of the test Mocking External Resources How can we create more sophisticated mock objects that have internal state and make their own internal state changes? Let's dive into these questions. • Use the create_response() helper method that builds response-like objects • Define a load_tests() function to combine the unittest suite with test examples found docstrings of sec11_v08_load • Provide the overall main program to run the complete suite Testing. 9 lectures 59:19 The Course Overview This video provides an overview of the entire course.
