How does testing help when adding new features to a Flask app?

Tests make sure new features don’t break existing code, so you can add safely and confidently.

Why should you write tests for your Flask app?

A To catch bugs early and ensure the app works correctly

B To make the app run faster

C To avoid writing documentation

D To make the app look better

Testing helps find bugs early and confirms the app behaves as expected.

What is a unit test in Flask?

A A test that checks the whole app at once

B A test that checks small parts like functions or routes

C A test that runs only on the server

D A test that checks the app’s design

Unit tests focus on small parts to verify each works correctly alone.

Which is a benefit of automated testing?

A It replaces the need for writing code

B It requires manual clicking every time

C It runs tests quickly and repeatedly without extra work

D It makes the app use less memory

Automated tests save time by running tests quickly and repeatedly without manual effort.

How does testing help when you add new features?

A It ensures new features don’t break existing code

B It slows down development

C It removes old features automatically

D It makes the app use more CPU

Tests check that new features don’t cause problems in existing parts of the app.

What happens if you skip testing your Flask app?

A Your app will always work perfectly

B Your app will need less code

C Your app will run faster

D You might miss bugs that users will find

Without testing, bugs can go unnoticed until users find them, causing problems.
