Why Is It Important To Test Database
Posted By : Reena Chungade | 31-Dec-2017
A database is the backbone of every software application and for complex applications, a stronger and secured database is the need of the hour. And for the applications which have higher repetitions of transactions, the cannot be handled by traditional databases.
We all being a user of software applications we know that all of us create, retrieve, modify and delete.
Create operation will be performed when any new transaction is being saved.
Retrieve Operation is performed when the user Views or Searches for any element.
Update operation is performed when the user Edits or Modifies
And Delete operation is performed if the user removes any record.
Also, it does not matter to the user which operation is being performed in the backend the user would anyways be doing either of the above-mentioned actions.
As a QA one can ensure database testing is done thoroughly. The following points to be kept in mind.
1. To test Data Mapping:
One should check how the database is mapped, it should be designed as per the documents or code. The basic idea is that the mapping between frontend and backend DB fields should be matched correspondingly.
For all the actions that the user performs the DB record should get updated with the click of save button.
2. To test ACID Properties of Transactions:
Atomicity, Consistency, Isolation, and Durability is what database system is expected to maintain, in order to make sure that accuracy, completeness and data integrity.
3. To test Data Integrity:
It is the maintenance of the assurance and consistency of the data in the entire lifecycle.
4. To make sure that the business logic is implemented accurately:
In today's time, DB is not just used to record data but to implement business logic correctly as well. Databases provide one with features like Relational Constraints, Referential Integrity, Triggers also Stored Procedures.
As a QA one must make sure that the implemented business logic works correctly.
