Database testing mainly tests the database structure, data tables and data calling relationships between the software systems according to the database design specifications.

Basic testing process:

Create query

In order to test the correctness and accuracy of the database. First of all, testers must be proficient in SQL and DML (database language) statements. Secondly, testers should understand the structure of the database. If these two conditions are met, you can test with confidence. It is a good testing method for applications developed by small and medium-sized technologies. In addition, if the program is relatively complex, the tester needs to ask the developer for help. But I suggest that you start testing from the basic level, so that you can have confidence and improve your SQL skills.

Query Data Table

Testers can verify the operation results of the application GUI by viewing the data table. However, this method is quite tedious and cumbersome for databases with large amounts of data. Validating multiple data tables is also quite difficult.

Query from Developer

This is the easiest way to test the database, perform any CRUD operation from the GUI and execute the respective SQL query, get the validation and its results from the developer. This approach seems to be the best way to test the database. If the developer finds that the statement is wrong or does not meet the user's requirements, the wrong statement can be modified as soon as possible.
