Database Testing Interview Questions and Answers

Q: What is normally checked for during a database test?

A: Database testing needs to include a field size evaluation, assessment of the constraints, indexes, and stored procedures.

Q: Which processes does database testing involve?

A: Data validity testing, data integrity testing, performance testing, and testing of procedures, triggers, and functions. Data integrity testing should be done in SQL queries.

Q: How do you check to see if a trigger is fired or not during testing?

A: This can be verified by querying the common audit log.

Q: Is a “fast” database retrieval rate a testable requirement?

A: No, all testing metrics need to be ambiguous. Any test should plainly state the performance or transaction requirements.

Q: How do you test whether a database is updated when information is entered in the front-end?

A: It depends on the application interface. If the application provides viewing functionality for the entered data, then you can verify that from the front-end only. This is typically how black box engineers verify the functionality.

Q: How do you test for stored procedures?

A: First, that tester should go through each requirement to see what purpose a particular stored procedure is written for. Then check whether all the required indexes, joins, updates and deletions are correct when compared with tables mentioned in the stored procedure. It’s also important to ensure that the stored procedure follows a standard format. Then the tester can check the procedure calling name, parameters, and expected responded for different sets.

Q: Describe the different stages of database testing.

A: There are five key stages:

  • Verify field-level data in the database with respect to front-end transactions
  • Verify the constraint
  • Verify the performance of the procedures
  • Verify the triggers (execution of triggers)
  • Verify the transaction
