Database Testing: What, Why and How to Test Database

All About Database Testing

Why should you opt for Database Testing?

  1. Database testing helps avoid hidden fault in an application. Identifying these faults is integral to testing as this ensures any possibilities of data loss, incomplete or incorrectly stored data before running it into your systems
  2. The GUI is the most critical part of an application. Proper database testing ensures that the database that’s incorporated within the app and appears on the GUI is validated for smooth user experience
  3. Proper database testing can help reduce the number of backend calls one may receive in case of queries from the end-user
  4. It also ensures that no harmful or incorrect data is saved at the backend of your application

Essential Questions you must ask before starting a Database Testing Routine for your Software

  1. Is the data set organized logically?
  2. Is the database performing well?
  3. Are the objects related to your database like views, triggers, stored procedures, functions etc. working correctly?
  4. Are you facing issues in storing the correct form of data in your data system?
  5. Is your data secured from unauthorized success?
  1. Is your data complete?
  2. Is your data factually correct?
  3. Have you eliminated any unnecessary elements from your data?

Database Testing Categories

1. Metadata testing

2. Data Quality Testing

3. Reference Data Testing

4. Database Procedure Unit Testing

5. Database Regression Testing

6. Database Integration Testing

7. Database Performance Testing

  1. Mask and refresh test data in the test environments from the production environment
  2. Generate a larger volume of test data using data generation tools

Database Testing Process

1. Identify the Scope

2. Set up the Testing Environment

3. Create a Test Scenario

4. Execute Test

5. Analyze

6. Report defects and monitor

7. Test Script Reuse

8. Cross-checking with UI Test Report

Important Guidelines and Tips for Database Testing

  1. List your requirements well in advance from all possible resources and map your requirements before proceeding with your test. This will help avoid chaos and any possible last-minute confusions
  2. Create proper text scenarios for each requirement and organize your data sets
  3. Ensure all the testing entities that you may require in your application is represented in the database. Also, ensure that unnecessary data elements are removed from your dataset
  4. Try focusing on response time to check your database performance accurately
  5. If you wish to test the database objects like stored procedures, make sure you design the test data in interesting ways and predict the output of the stored procedure
  6. Try designing invalid test data sets to check database constraints and update them in your database
  7. To do security testing for your database, try designing tests that mimic unauthorized access. This would show if you can view, modify or delete the restricted database for future use
  8. Design valid test data set for all application entity to test proper data integrity. Ensure each data in the test data set has been inserted/ updated in the database
  9. Try keeping your queries as simple as possible to prevent defects in your SQL queries
  10. Try getting your queries reviewed by someone other than the author of your test code to review the queries

Misconceptions related to Database Testing:

  • The process is too lengthy to be executed at a go: it’s super simple and easy to execute
  • Database testing adds more bottles necks in the testing process: it clears down process makes a testing a lot smoother
  • Testing slows down your overall development process: it adds efficiency in your work and reduces the chances of redundancy
  • It adds cost to your IT testing budget: It’s anytime worth the investment
  • It requires an in-depth knowledge of SQL that can be exhaustive: even the most basic awareness about SQL is enough
