Running the Debugger
The Python debugger can be utilized in several different ways The pdb module is the Python debugger. You can access it by importing it directly either in a script or in the Python console With the debugger module imported, you then have access to many different functions for debugging. This is especially useful if you import the module from Python's interactive interpreter, so let's look at an example of doing that now. Download the supplemental code from the website for Chapter 10. From that...

The following example shows how to start a service, stop a service, restart a service, or get service status through Python def service_info action,...
Testing Eib
There are several moving parts with this application, so there are several potential areas for testing The tests in this application are fairly simple and trivial. You could expand on the test suite by testing a real application, and see what issues or problems arise. This framework could even be used with the Python unittest module, which is covered in Chapter 10. Examine the XML files that are being created, to verify that the format of the files is consistent and expected. Create a suite...
The winnet Module Access Windows Networking Features

Modifying the Program Nsm
There are several ways this project could be enhanced, including the following Currently, the application saves test data by date, such that multiple runs on one day overwrite each other. You could change this behavior by having the files use a date-time stamp. You could have an option to look at test history, which takes the name of a test as input and then goes through each test run and produces a report of each result, based on the date. You could create command-line arguments so that, for...
