Summary

Testing, debugging, and profiling are high-level tasks we can use to analyze applications to look for improvements in correctness and performance, but they can be quite confusing to beginner developers. PyCharm offers straightforward and intuitive interfaces for these processes, making them more accessible and streamlined.

Unit testing is the process of making sure the individual components of a large system work as intended. PyCharm has convenient commands to generate test skeletons/boilerplate code that usually takes time for developers to write manually. While testing a program, it is important to consider expected faults, as well as the obvious tests for intended functionality.

In a debugging session, developers attempt to narrow down and identify the causes of bugs and errors that are detected during testing. With a graphical interface, combined with various options to track the values of variables throughout a program, PyCharm allows us to debug our programs dynamically...
