Deployment Made me Realize why TTD is a thing....

Not a technical post, rather a section from my journal. A Snippet from my technical journal 08/03/2026 18:31 Am in the process of deploying the 2nd iteration of my project and am now understanding why test driven development is a thing, per my limited experience. When your project reaches deployment stage or rather you rush to it, you add a whole new set of issues to the process. So if you program is buggy in the first, it becomes (way not harder or complex, per say), but rather cumbersome and tiring. You are battling on 2 fronts now, the deployment and the program itself. Kept it raw for reasons. Also, I have a few questions. I will start writing test cases for my new projects and upcoming iterations, so how do decide what test cases to write and when to stop? I have FOMO and Imposter Syndrome, so is render the right choice for deployment? Goal is to a paid internship. Do you have a system or flow in place for Django projects to be deployed eventually specifically? Systems do help me
