Introduction
In any software development, processing and storing data in different states shows the business rules an application is generally built on. The database is the most crucial part of any software development. It needs to be well-built to serve the necessary data processing requirements and storage needs of the application. In order to test the feasibility and functionality of the application, database testing is a crucial step. If you look to learn more about it, Database Testing Training in Gurgaon can be the best platform. It is important to learn this testing process in brief to efficiently carry out the testing process.
What is Database Testing?
Database testing generally includes constructing SQL queries to validate various database operations, and defining structures and attributes essential for the database application.
This process starts by validating the schema and further testing CRUD operations and transactions to ensure that the database is correctly set up. These tests can be completely automated, fully manual operation, or just a hybrid approach. In the case of a fully manual test, you can get into the database management system to validate assumptions. Or just check the application UI to check that it returns the appropriate data after an operation.
Database testers generally work with application developers to efficiently test the scenarios of the operating database.
Why is database testing important?
In a situation where there is any error in an application, it can further lead to heavy monetary losses that may cause the collapse of the complete business. In order to save your reputation and the integrity of your organization you need to look after efficient formats for database testing.
Some known reasons for testing databases are:
To secure you from all kinds of attacks like SQL injection attacks
Make sure there are no network issues or power outages affecting the integrity of data or leading to data loss or corrupted data
To remove any kind of errors from the database or to maintain the overall quality of data
For ensuring the correct storing of data in the right format
To integrate relationships between entities, present within the database
What should You test?
Once you understand all parameters of database testing, you can then apply what you know beforehand to ensure that all test cases are well covered.
CRUD
The initial set of test cases is for the sections of Create, Read, Update, and Delete (CRUD) operations. It ensures that data is correctly stored and retrieved in the correct manner to assure data integrity. A tester can even do this directly from the application interface.
Transactions
Transactions are basically sensitive database operations since they need various queries to perform essential recovery from failures. A standard database transaction further follows the ACID principles.
Atomic: Requires to complete all operations or may perform no operation at all
Consistent: A valid state of the database and all necessary constraints to follow
Isolation: Each transaction needs to perform in isolation from other transactions running at the same specific time.
Durability: Causes no data loss for any reason
Schema
The database schema acts as the version of the blueprint of the overall database structure, thus testers require to be well familiar with and understand it. Testers can further use SQL commands to ensure that it meets the application expectations. Testers even make use of some regular expressions to check table field names and confirm that it meets the expected data type.
Triggers
Triggers act as a handler in code. When any operation takes place, a trigger sets up to execute a piece of code in response to the operation that just took place. Triggers develop a cascade effect on some kinds of operations.
A tester can further run an SQL query to begin the original operation that may trigger the cascade. Additionally, the tester could even perform the operation from just the basic application’s interface. Further examining its overall effect on the complete database records.
Conclusion
Database testing ensures application reliability. Data sits at the core of all applications to ensure that users can trust your applications with the correct data. With Database Testing Online Training in India get trained in this domain to perform your work efficiently. Moreover, learning this testing will help you in elevating your testing knowledge. Hence, start learning and growing in your testing career.
