Why testing matters in Node.js - Quick Recap

Recall & Review

beginner

What is the main purpose of testing in software development?

Testing helps find and fix errors early, ensuring the software works as expected and is reliable.

beginner

How does testing improve software quality?

By catching bugs before release, testing makes software more stable, secure, and user-friendly.

intermediate

Why is automated testing preferred over manual testing in many cases?

Automated tests run faster, can be repeated easily, and reduce human error compared to manual testing.

beginner

What risk does skipping testing introduce to a project?

Skipping testing can lead to undetected bugs, causing crashes, security issues, and unhappy users.

intermediate

How does testing save time and money in the long run?

Fixing bugs early is cheaper and faster than fixing them after release, reducing costly downtime and support.

What is a key benefit of running tests automatically in Node.js projects?

A Tests require manual clicking each time

B Tests run quickly and can be repeated anytime

C Tests only check the user interface

D Tests make the code run slower

Automated tests run fast and can be repeated often without extra effort.

Why should developers write tests before releasing software?

A To avoid writing documentation

B To make the code longer

C To find bugs early and improve reliability

D To slow down the project

Testing early helps catch bugs before users find them.

What happens if software is released without proper testing?

A It may have hidden bugs causing problems

B It will always work perfectly

C It will run faster

D It will not need updates

Without testing, bugs can remain hidden and cause issues later.

Which of these is NOT a reason why testing matters?

A Improves software quality

B Saves time and money

C Helps find bugs early

D Makes software harder to maintain

Testing actually makes software easier to maintain by catching issues early.

How does testing help users?

A By making software more reliable and secure

B By making software more confusing

C By hiding errors from developers

D By slowing down the software

Testing ensures users get a stable and safe experience.

Explain why testing is important in software development.

Think about how testing affects both developers and users.

Describe the risks of skipping testing before releasing software.
