Database Testing

Data security is critical to any business’s success, making database testing a very important part of the software development and deployment lifecycle. Proper testing may make databases more robust, secure and scalable. Data Integrity is at the core of database testing and a team of qualified test engineers can help you establish the most relevant and holistic database testing strategy, to enable your data to be more accessible and reliable.

Our comprehensive multi-platform database testing expertise allows us to deliver value-based, cost-effective services that ensures the integrity, reliability, usability and scalability of your data. Our test engineers have extensive experience and expertise across various technologies and domains. They pay attention to detail and to all the important aspects of data such as data mapping, data integrity, and data security.

Advantages Of Database Testing:

  • Database testing ensures that your software works as intended, without any abnormalities.
  • It empowers you to discover defects during the initial stages of development.
  • It simulates real-world business case scenarios.

Our Database Testing Service Process

RT has a well-defined QA process that helps in validating and improving the quality of the tested software. Our certified test engineers have extensive experience working on IT projects of different levels of complexity. While in most cases, manual testing is an integral part of custom software development, RT also offers manual testing services as a separate offering.

Core activities covered in our Database Testing

Data Mapping

In software applications, there is a continuous interaction of data between the user interface and the database. Because of this frequent interaction of the UI with the database, there are certain aspects of data that needs to be taken care of such as:

  • Validate the mapping of the UI form fields with the corresponding columns in the database on a regular basis and verify with the business requirements documents.
  • Check for the successful completion of every user action. For eg when a user performs a specific CRUD operation (Create, Retrieve, Update, Delete), the corresponding action gets triggered in the database.

Acid Properties Validation

As a thumb rule, for every transaction, a database must obey four properties – Atomicity, Consistency, Isolation, and Durability, which are also included in our services.

  • Atomicity: This can be interpreted as a binary property, which means a transaction will either fail or pass, which means that if any part of the transaction fails, then the entire process will be marked as failed.
  • Consistency: This implies that every transaction will result in a valid state of the database.
  • Isolation: This implies that when multiple transactions get executed concurrently, results and the state of the database should be similar.
  • Durability: The transaction should be such that once it gets executed, any external factors should not be able to change the state of the database.

Data Integrity

For successful CRUD Operations, it is important to ensure that the last updated recent values of any shared data are reflected on all the user interfaces (forms, screens etc). And the values should be the same type.

‘CRUD’ operations are initiated by the database tool and are executed by the end-user on the software application.

  • C: Create – operation is triggered when the user ‘Saves’ any new data through a transaction in an application.
  • R: Retrieve – This operation is triggered when the user views data for any saved transaction.
  • U: Update – This operation is triggered when the user chooses to modify an existing record.
  • D: Delete – This operation is triggered when the user chooses to remove a particular record from the system.

For database testing to be effective, all the database test cases need to be designed in a way that they verify and validate the data to ensure its consistency.

Business Rule Compliance

For complex databases, components such as triggers, relational constraints, views, stored procedures, etc. need to be verified and validated as per the business requirements.

Database Testing Guidelines

The guidelines mentioned below are a starting point to prepare good test cases for database testing.

  • Establish clear functional requirements.
  • Establish all the joins used between tables
  • Establish cursors and triggers used
  • Establish stored procedures used
  • Establish all the Input/Output parameters used.
  • Create test cases with multiple scenarios of input data and cover all functional paths.

Database Testing Checklist.

Once the test cases are documented, you can turn to the following checklist to ensure you covered all aspects.

  • The tests case incorporates all the database tables to cover every requirement.
  • If your software/database is using any status flags, then ensure that your tests verify each of them.
  • Ensure that your test cases have the triggers/stored procedures with multiple scenarios of input/output.
  • Test cases should validate columns with default values.

FAQ Database Testing Process

What is required for database testing services?

A good test engineer will have a thorough knowledge of the database components to execute good database testing services including functions, stored procedures, indexes, views, keys, and excellent hands-on SQL skills.

Why are database testing services important?

Database testing services ensure the verification of all input data and the consistency and integrity of the data stored in the tables. It trims data loss, saves aborted transaction data, and prevents unauthorized access to information.

Is it possible to automate database testing services?

Yes, database testing can be automated to ensure the performance and functionality of the database. It can prevent crashes, broken insertions or deletions, and failovers. Database test automation strategy plays a key role in establishing database automation test cases.
