What is Database Testing?
Database Testing is a type of software testing that checks the schema, tables, triggers, etc. of the Database under test. It also checks data integrity and consistency. It may involve creating complex queries to load/stress test the Database and check its responsiveness.
Why Database Testing is Important?
Database Testing is Important in software testing because it ensures data values and information received and stored into database are valid or not. Database testing helps to save data loss, saves aborted transaction data and no unauthorized access to the information. Database is important for any software application hence testers must have good knowledge of SQL for database testing.
The GUI is usually given the most emphasis by the test and development team members since the Graphical User Interface happens to be the most visible part of the application. However, what is also important is to validate the information that is the heart of the application, aka DATABASE.
Let us consider a Banking application wherein a user makes transactions. Now from Database Testing or DB Testing viewpoint following, things are important:
- The application stores the transaction information in the application database and displays them correctly to the user.
- No information is lost in the process.
- No partially performed or aborted operation information is saved by the application.
- No unauthorized individual is allowed to access the user’s information.
To ensure all these above objectives, we need to use data validation or data testing.
