Why database testing ensures data integrity in Testing Fundamentals - Quick Recap

Recall & Review

beginner

What is data integrity in the context of database testing?

Data integrity means the accuracy, consistency, and reliability of data stored in a database over its entire lifecycle.

How does database testing help maintain data integrity?

Database testing checks that data is correctly stored, updated, and retrieved without corruption or loss, ensuring the data remains accurate and consistent.

Name one common type of database test that supports data integrity.

Constraint testing, which verifies rules like primary keys, foreign keys, and unique constraints to prevent invalid data entry.

Why is it important to test database transactions for data integrity?

Testing transactions ensures that all parts of a data operation complete successfully or none do, preventing partial updates that could corrupt data.

beginner

What real-life example can explain data integrity in databases?

Like a bank account balance that must always be correct after deposits or withdrawals, database testing ensures data stays accurate after changes.

What does database testing primarily ensure?

A Faster database queries

B Data accuracy and consistency

C More storage space

D Better user interface

Database testing focuses on ensuring data is accurate and consistent, which is data integrity.

Which of the following is a key part of maintaining data integrity?

A Testing database constraints

B Ignoring constraints

C Deleting data randomly

D Skipping transaction tests

Testing constraints like primary keys helps prevent invalid data, supporting data integrity.

Why are transactions tested in database testing?

A To ensure partial updates happen

B To speed up data entry

C To reduce database size

D To make sure all parts succeed or fail together

Transactions must be atomic; testing ensures they fully complete or rollback to keep data consistent.

Which is NOT a goal of database testing for data integrity?

A Preventing data corruption

B Ensuring data consistency

C Improving user interface colors

D Validating data accuracy

User interface colors are unrelated to database testing and data integrity.

What real-life example helps understand data integrity?

A A bank account balance after transactions

B A random number generator

C A broken clock

D A weather forecast

A bank account balance must always be accurate after deposits or withdrawals, similar to data integrity.
