What is Testing? – Testing in Python

Testing is a very import concept in Programming not just in Python. Although, we start off writing simple script files with few lines of code. You start getting thousands and millions lines of code, hundreds of Python files worked on by many people from different divisions in a company and most likely all of them starting at different time at company.

All the code changes happing over time at different time as people work on the project as the complexity of the code and the size of the code increases. It becomes harder and harder for someone to fix a bug that may arise.

Use of Debugging in Companies

Let’s say you come into a project that has been around for year and you modify something that may modify another part of the app that you deem and think of. You start creating all these bugs with new features that you introduced into the app. The longer that the code stays in a project the more likely it is to be touched by the different developers.

So, you see the problem here and for companies this is a huge problem because you are most likely growing your product and adding more and more lines of code. That means there’s just going to keep making this giant monster that becomes harder and harder to tame and debug. It costs company a lot of money. Luckily for us we have something called testing.

If you have hundred files of Python or modules then each of those modules will have its own test file that you can run test with. The test file is never going to be run in the production. It’s a file that we run to make sure that before we release your main file to production, test file check everything working properly. So, test is only for development.
