Database or backend testing is important because if it is not done properly, it may cause some serious complications like deadlock, data corruption, data loss, etc.
How to do Backend Testing
Database testing mainly includes validating
Schema Database tables Columns Keys and Indexes Stored procedures Triggers Database server validations Validating data duplication
In back-end testing, you are not required to use the GUI; you can directly pass the request through some browser with the parameters required for the function and get a response in some default format. Example, XML or JSON. You also need to connect to the database directly and verify the data using SQL queries. Through log files, debugging can be done. There are various phases in back-end testing. The first step is to acquire design specifications for a database server. The next step is to test the specification design, followed by implementing the tests in this design with SQL code.
Types of database testing
The types of database testing include
Structural Testing Functional Testing Non-Functional Testing

Advantages for back-end testing
Back-end testing is not like a Black Box Testing Full control of Test coverage and depth In the early development stage, many bugs can be effectively found
In order to do the back-end testing, the tester is expected to have a strong background in the database server and knowledge of structured query language. Further Reading – https://www.guru99.com/data-testing.html
