What are some methods for increasing the speed of debugging in Python + Django + PyCharm on a Windows operating system

Enhancing Django Debugging with PyCharm.

Every time I try to debug something, the process runs terribly slow.

The start-up time for Django is excessively long.

Let me clarify - I am a big fan of PyCharm for its comprehensive debugging features...and Python in general is much simpler and faster to debug compared to other languages like C. Despite optimizing my PostgreSQL database for testing (Optimise PostgreSQL for fast testing), using an SSD drive and i7 quad-core CPU, and configuring my antivirus not to interfere with system directories, it remains sluggish.

Any suggestions on how to expedite the debugging process?

I am particularly interested in reducing the start-up time, as most of my debugging involves single unit tests.

Answer №1

To run Python code normally but with debugging capabilities, you can insert the following line in your script:

... code before ...
import pdb; pdb.set_trace()
... code after ...

This will halt the execution of the code at that specific point, allowing you to inspect variables and step through the code using commands like 'c' (continue), 'q' (quit), or 'n' (next). You can also view the current position in the code by typing 'l'.

While this method may speed up the overall execution time of your code, debugging may become a more challenging task.

Answer №2

A solution to a problem I encountered in the past was discovering that Django and PyCharm provide an option to run individual tests instead of the entire test suite whenever I want to debug my code.

To achieve this, all you need to do is update your Debug configuration in PyCharm. Simply adjust the target to point to a specific module, class, or method deep within your test files.

To successfully accomplish this, make sure that your directories are considered modules (e.g., ensure the presence of a __init__.py file). You can now specify targets using the following format:

django_app.tests_module.test_case.test_method

The exact target "path" will vary depending on how your project is organized.

Remember to switch back to running all tests once you have completed your implementation, before pushing your code ;)
