What problems can happen if a FastAPI project has no clear structure as it grows?

Code becomes hard to find and fix, bugs increase, and new developers struggle to understand the project.

How does a good project structure support testing in FastAPI?

It makes it easier to write and run tests for each part separately, ensuring the app works well as it grows.

Why should you separate routers, models, and services in a FastAPI project?

A To keep code organized and easier to maintain

B To make the project load faster

C To reduce the number of files

D To avoid using databases

Separating code by function helps keep the project clean and easier to update.

What is a risk of having no clear project structure in a large FastAPI app?

A The app will run slower

B Code becomes confusing and hard to fix

C You cannot add new features

D The app will not start

Without structure, code is hard to understand and bugs increase.

How does a good project structure help new developers joining a FastAPI project?

A They only work on the database

B They do not need to read any code

C They can skip testing

D They can find code quickly and understand the app

Clear structure guides new developers to the right files and logic.

Which folder would you expect to find API endpoint definitions in a well-structured FastAPI project?

A routers

B models

C services

D tests

Routers usually hold the API routes and endpoint logic.

Why is testing easier with a good project structure in FastAPI?

A Because you only test the whole app at once

B Because tests run automatically without code

C Because code parts are separated and can be tested individually

D Because testing is not needed

Separation allows focused tests on each part, improving reliability.

Explain why organizing a FastAPI project into folders like routers, models, and services is important when the project grows.

Think about how separating tasks helps in a team project.
