How Database Testing Can Enhance The Quality Of Deliverables?

Introduction

Database Testing — Is It Really That Important?

Advantages Of Database Testing

  • It facilitates the complete prevention of test coverage.
  • It allows you to discover issues or bugs easily and effectively in the initial phase of development.
  • Thorough database testing ensures that your product performs effortlessly.
  • It uses powerful management tools.
  • Concurrency read and write are available so you can use transactions.
  • Easy to use; you can use SQL language to perform actions like query and insert/update/delete.

What Components Need Testing?

  • A transaction can begin using BEGIN TRANSACTION #NO and ended using END TRANSACTION #NO.
  • We can test Data consistency with the help of ROLLBACK, while SELECT can retrieve the data.
  • For example, when a user creates an account for a website, some benefits are provided to the user. On the database front, a trigger associates the newly acquired benefits for the new user’s account.
  • One way to verify the triggers is by executing the independent queries of the trigger and verify the outcome by executing the trigger as a whole.
  • Triggers can also be tested directly from the UI by, performing an action and querying the database and matching the expected outcome with the actual data which is existing in the database.
  • Execute all the stored procedures and then test all the database entries, after every execution, and make sure that you do it sequentially.
  • The sequential execution will help in breaking down a complex transaction into small crunches and also help in validating every small step.
  • We can trigger the stored procedure by performing different user actions and then verifying the outcome.

Database Testing Must Include The Following Processes

  1. Data Validity Testing: For this, testers must have intermediate knowledge of SQL queries.
  2. Data Integrity Testing: For this, testers must understand and be able to apply referential integrity and constraints.
  3. Performance Testing In Relation To The Database: For this, testers should have proper knowledge of the structure of the table and its design.
  4. Procedure Testing Functions Testing And Triggers Testing: For this, testers should have basic knowledge of the program and logic flow.
  1. Data Mapping: Table mapping, column mapping, and Data type mapping, Lookup Data Mapping
  2. Four Properties Validation: The main 4 properties are known as ACID properties where it represents ‘Atomicity’, ‘Consistency’, ‘Isolation’, and ‘Durability’.
  3. Data Integrity: Data item appears only once, and the updated value is immediately available to all users.
  4. Backup & Recovery: Automatically create the backup of data and restore data-id required.
  5. Data Redundancy: Data item appears only once, and the updated value is immediately available to all users.
